Tamrac Adventure 10 backpack

The Adventure 10 is a mixed hiking and photography backpack from Tamrac. This means that, contrary to the traditional photo backpacks, which only function is to carry and protect photographic equipment, this particular pack includes in its design an additional separated top compartment suitable for the transportation of items normally needed by nature excursionists, e.g. additional pieces of clothing, food, hiking equipment, etc.
This versatility makes it the right photography backpack for any hike that takes you farther from the parking lot, giving you a higher autonomy in anything that exceeds a morning or a afternoon walk.
I'm growing rather fond of my Tamrac Adventure 10 nowadays. Why? Well, in Summer time, here in Madeira, there isn't much we need in the hills except a couple of boots in our feet, a hat, a t-shirt or a polartec fleece and a pair of shorts. For food you carry a couple of power bars or snacks and for drinking you just need a filled up 1 liter water bottle. That's all. During that gentle season, my favorite photographic pack is the trusty Lowepro Inverse 200 AW belt pack. It has plenty of room for a Pro (D)SLR, together with a couple of lenses and a flash, and can also carry the needed food and drink.
In the Winter season, now starting, it's another story. The weather becomes unpredictable in Madeira's highest peaks and trails. The natural excessive humidity in the air, the sudden rain showers, the stronger winds and the low atmospheric temperatures, all conspire to change a peaceful walk in the hills into a living hypotermic hell in a very short notice. In those moments the difference between panic and self-control is proper equipment and preparation.
 
For the actual preparation you have to start working months before. You have to know your trade. And being an experienced hiker, as in all human activities and endeavors, requires commitment, dedication and time. Grouping the necessary equipment is easier. You don't need to be a PhD for that. You just need to follow a check-list taken from the web. Using it properly, however, requires you to reread the above paragraph.
Well, the first piece of equipment for us nature photographers of the Northern Hemisphere facing the arrival of Winter might as well be this dual-purpose backpack, that will allow us to carry, besides photo gear, all the other items to make our walks in the wilderness a bit more comfortable. A rain poncho or a Gore-Tex jacket, a all-weather cover for the backpack itself, additional dry clothes, a flash light, a mobile phone, a compass and charts or a portable GPS - don't forget a whistle and a signaling mirror - are all items that I stow religiously on the Tamrac's top compartment.
If I can find a negative detail on the Tamrac Adventure 10, this is, without doubt, its harness, back padding and straps system. These are quite simple and - it doesn't really matter how much you try to adjust them - you'll have a hard time trying to equilibrate the pack on your shoulders and back. Not nearly in the same league as the Lowepros. But for the luxury of an internal aluminium frame, you have to be prepared to pay twice the price. As in many things, you get what you pay for. Zippers are also far from perfect, being a little stiff and the opening of the top compartment could be better engineered. Besides that, this particular pack doesn't bring an all-weather cover. So, if you are planning hikes in rainy conditions, you better buy one on the E-Bay, from the many Chinese sellers out there. Four or five Euros should do the trick.
The 17' laptop compartment (visible here, near the back padding) is a must, and, due to that, this backpack quickly became my all-around carry-on air travel bag, allowing me to bring on the cabin all the valuable photographic and personal items that, otherwise, I'd have to send to the hold.
Two mesh pockets on either side allow for a small tripod transport or a water bottle. Along the pack's body and straps there are several points for connection of accessories of the M.A.S and S.A.S lines, also compatible with several accessories from other makers.
Bottom line: if you want a dual photo backpack that does the job, without damaging excessively your bank account, you will not make a mistake. The Adventure 10 is a reliable piece of equipment, with plenty of load capacity, without the bells and whistles that characterize more expensive options. However, if these bells and whistles are important for your needs, you should look nearby, on the higher specialized Lowepro competition.

My first AI lens

As many photography lovers, I would never give up film photography if it wasn't for the slow decline of the support system behind us.
Nearly ten years ago, when I shifted from a seafaring career to a more terrestrial one, I still could find a laboratory in Funchal able to process positive films. A couple of years later, with just a handful of last clients, they were forced to close the service and, consequently I, too, reluctantly, migrated to digital, with my first acquisition in the field: a Nikon D40X and its standard Nikkor 18-55mm AF-S zoom.
And I emphasize "reluctantly" because, back then, I knew I was opening a Pandora's Box full of superfluous things, many of them not truly indispensable for our photographic endeavours. Menus, auto-ISO's, VR's, autofocus I, II and III and so on, were designed to make our life easier in the field. To make picture taking simpler and intuitive.
On the contrary, and most of the times, these modernisms, as Ken Rockwell wisely pointed out, gives us more chances to loose a photo opportunity than to achieve one.
On those frustrating moments, I wish for simpler techniques and equipment. Anything that returns to us the simplicity of the photographic act.
Nikkor AI lenses mean just that: simplicity and effectiveness. Just an optical tube with both manual focus and diaphragm rings. It just doesn't get any simpler.
Understandably, and since all these lenses were designed in the film age, you have to be smart while buying a modern digital body fully compatible with their manual iris selector.
But even if you own the simplest of the Nikon digital bodies, these lenses remain perfectly usable. You just have to guess the exposure or do it by trial and error.
After all, it's the digital age. What do you have to loose? Card space?
And have I told you that they are really cheap, bought second-hand, on E-Bay, these days?
The notable Japan-made Nikon Nikkor 50mm f/1.4 AI, bought second-hand on E-Bay, from the competent Japanese seller AIHALAND-JP. 110 Euros of solid metal and glass, as Ken Rockwell wisely points out, "...built like a tank for a lifetime of great pictures.".
The quality on the details is simply amazing. Reminiscent of an era when handcrafting perfectionism was a standard industrial procedure. Note the detailed depth-of-field scale, painted with the same colours of the numbers on the diaphragm scale. Small red dot for Infra-Red focus correction also present.
The aft part of the lens, showing its bayonet mount and the diaphragm activating lever. 257 grams (naked) of solid construction with, in my modest opinion, just one drawback: a minimum focus distance of 0.45 mts. But, anyway, this was normal for a 50mm lens of that era. If you want to focus closer, you might prefer one of the fabulous - according to many reviews - Micro-Nikkors 55mm f/2.8. You'll loose speed, however.
Nikkor 50mm f/1.4 AI focused at minimum distance at f/2.0. No so bad bokeh, don't you agree? Shot with a Nikon D610.
In hyperfocal focus, from foreground to background, in the distant horizon. Shot at f/8 with a Nikon D610. Sharpness all over, so it seems. Notice the tree branches?

Cheap wide angle and close-up lens for the Nikon P7100

I'm getting more and more fond of the Nikon P7100 over time. It's a compact, granted. But it's a serious compact, with complete manual override of its automatic functions. And regardless of what many bloggers might say, I really enjoy the (although small!) optical viewfinder. Adding to so many functions and versatility, you have also the possibility to shoot RAW (NRW) files. Forgetting the small sized sensor and the obvious problems associated with that, this camera is pretty much portable and quite capable of professional results. It's as close as you can get to the Leica M and the "decisive moment" philosophy by a mere 300 bucks.
But it still is a compact. And despite a professional-grade body build, we are limited for all the eternity with a fixed 6-42.6mm f/2.8-5.6 (optically competent, 28-200mm-35mm equivalent, lens). Aware of this limitation, it wouldn't take long for the market to come up with a few solutions to extend its optical versatility.
A kit that is, probably quite popular, is the wide-angle/macro adapter. There are several of these on the market. Nikon, particularly, has its own (the Nikon WC-E75A lens used in conjunction with the UR-E22 adapter ring). But with a price tag of about 200 Euros I started immediately looking for cheaper alternatives. And if you search E-Bay, like I did, you'll probably will find several ones, beginning at 20 or 30 Euros. These kits are basically composed of three pieces: an adapter ring (or extension tube) and two lenses. Well, in a way it's actually a single wide lens that has the ability of being separated in two. To use the kit on its basic wide-angle function, you attach both lenses to the extension tube and all the kit to the camera body (after removing from the body the camera's attachment ring surrounding the lens).
If you want to use this useful accessory as a close-up device, you just separate the lens in two components and attach just its "Macro" lens to the extension tube. And voilá... you have two useful lenses in one.
The typical wide-angle and macro lens adapter kit that you can buy on the E-Bay, made by several independent makers, is normally composed of these items: an extension tube (used to connect the lenses to the camera body) and the optical kit, generally composed of two screw-down lenses. To use the kit as a wide-angle adapter both lenses have to be connected together. But if you unscrew the wide-angle front element, you can use the Macro one as a close-up accessory. Two lenses in one. Not bad for 30 Euros.
 
Just pay attention to one detail: not all the independent extension tubes on the market are a perfect copy of the original Nikon UR-E22. Meaning that the original Nikon accessory has two "dents" that interact with the camera body and blocks the zoom lens to extend more than its 28mm position (the shorter length), thus preventing serious damage to the lens if you zoom it with the accessory lens mounted on the body.
All these wide-angle kits that you can buy are to be used with the zoom in its minimum position. Naturally. However, if you are buying an independent one (as I did), just make sure that, after being installed on the camera body, the extension tube interacts with the camera's electronics and doesn't allow the zoom range to extend. It's easy to test that. Just install the extension tube on the camera (without the front lens) and try to zoom afterwards. If the lens doesn't respond, it means that you bought a "safer" kit. And therefore you are protected from a serious damage if, by mistake, you operate the zoom lever when using the kit lens.
You can, also, always go to the camera's menu and switch on the "wide-angle converter connected" mode. That way, you will be protected no matter what. Just don't forget to switch it off after removing the kit lens, or you'll go mad trying to understand "why doesn't the bloody camera zoom? It was working perfectly until a few hours ago!".
Without the wide-angle lens...
...and with it. Although the angular difference is not that great, it can, however, in particular circumstances, make a difference. And for thirty bucks... who's complaining?
My trusty Nikon Coolpix P7100 with the wide-angle/macro kit lens adapter bought on E-Bay by a mere 30 Euros.

SLR Magic Hyperprime 12mm T1.6

Yay!
Just received my new lens. I was looking for a cheap fast wide angle alternative to the Olympus M.Zuiko Digital ED 12mm f/2.0 for my m4/3's Panasonic GH2 for quite some time. Sadly, the market doesn't offer so much.
In fact, regardless of the Samyang 7.5mm f/3.5 UMC Fisheye MFT - which is also not fast enough - there is little on the market, except for the above said very expensive Olympus one. So the arrival to the market of this lens (equivalent to a 24mm field of view in 35mm photography) is certainly welcome. Sadly, the reviews about it don't abound, and most of the ones existing are basically generalistic approaches (like this one) to the lens themselves.
A few technical ones that speak about this lens performance are a bit inconclusive. Some say it's a good product, some complain about its softness.
Two great reviews (one from Steve Huff and the other from The Phoblographer) were my starting points to learn a little bit more about this much needed product for the m4/3's community.
Later on, I checked also this one (from the Kanauru Productions guys). It's a very detailed review, comparing the SLR Magic with the (expensive) Olympus alternative.
All of them are good starting points to learn a little bit about this little (really!) piece of glass. The rest of it, like everything in life (even with well-proven equipment), is a leap of faith. Particularly if you are buying, on the web, a Chinese product from a commercial house in England and you are living in Portugal. Well, sometimes we just have to make the Sign of the Cross, forget the International Warranties (if they exist!) and... clear the way. Click the "pay" button and, afterwards, make daily visits to the mailbox.
Well, so far so good. I have it with me already. And what surprised me the most was that it's really a tinny piece of equipment.
You can see the box size here, near a One Euro coin. The box measures about 9.5*6.8*6.5cms and the lens is even (naturally) smaller. So if you are expecting that 540 Euros will buy you a big piece of kit... forget it. It's a little bit more like this:
On the other hand, I guess this is the main reason why we all (under certain situations) love the m4/3's format: its size. Regardless of its small size this lens seems to be a greatly built product. It's heavy (about 330grs) and as far as my eyes can see it has a full metal construction. In fact the only plastic I've noticed on it so far is the rear (bayonet) cap. The front one (screws on the filter 58mm thread) is solid metal. I can only expect that they were not cheap on the optics. But, about that, I can only tell you later. When I start using it.
As you can see, and contrary to conventional photographic lenses, the ring order is reversed. Closer to the mount you have the focus ring and closer to the front element you can see the (smooth and clickless) aperture ring. Both rings, although well dampened, are a bit to the "stiff" side. But lets not forget that this lens was designed with cinematography (videography?) in sight. So, used under these circumstances, with the already common DSLR racks and follow-focus units, this detail is, probably, not so conspicuous.
The front element of the SLR Magic Hyperprime 12mm T1.6. The words "Cine" and "T1.6" are not there by mistake. The lens was built with cinematography in mind. Regardless of that eventual future use, I bought it because I needed a fast wide angle for night landscape photography and the alternatives were either very expensive or less luminous. The obvious drawback is that this is a complete manual lens. So, forget about Auto Focus and Auto Aperture. All manually done... and with a smile on your face, because nobody forced you to love this hobby. Keep on shooting.

Sirui T005 - The ultimate travel light tripod?

For us, outdoor photographers, a tripod is not a luxury. It's a necessity. However finding the good perfect one is, probably, impossible. Let's see what is, normally, for us the definition of a perfect tripod: it has to be, simultaneously, light, small, stable, durable and... cheap.
A piece of equipment that unites all these characteristics still has to be invented. So we diversify. Any person that is a little bit serious about photography will end up acquiring at least two tripods: one, normally heavier, when maximum stability is paramount, and a lighter unit when (as Galen Rowell wisely pointed) it's better to take a light tripod than no tripod at all. Normally the latter is the problematic one. Until now my lightest tripod was a Manfrotto 190XDB that I used with their lightest ball head (the ProBall 308 RC). However, although stable, this combo is still heavy for a person that likes packing light and in most mountain trails it's already on the limit of what we can, comfortably, transport on our hands. In mountain trails, on steep terrain, if we need both our hands to help the progression, the last thing we need is one of them occupied in handling a tripod.
In those circumstances (quite common in Madeira, actually), we might choose one of three possibilities: leave the darn thing behind, strap it to the rucksack or use a tripod strap and pass it over your shoulder. Since I don't wear a rucksack (on daily hikes I enjoy very much my Lowepro Inverse AW200) and in my modest opinion the use of tripod straps is a good way to compromise your equilibrium in more technical steps, I went shopping for a tripod light enough to strap to my waist pack without damaging it and at the same time sturdy enough to allow for some sharp pictures. Galen Rowell used to talk about two which he considered as good options: the Gitzos 001 and 026.
Sadly the prices of Gitzo material are anything but accessible, so I tried to find a cheaper alternative.
And, in this particular case, it appeared as the Sirui T005.
The tripod comes in aluminium (in a choice of three different anodized colours: black, blue and red) and in a carbon fiber version. I bought the version shown in the above picture and one thing I can tell you: it's really light.
 
It's Gitzo look-a-like construction is visible particularly on the rubberized twisting leg-locks and the quality construction is patent on the machined parts of all the structure. With the legs (five sections!) fully extended, opened in minimum angle and with the center column not extended (as shown in the picture) this light piece of kit has the head's base plate at 1.20mts from the ground. With the additional extension of the center column (it's a telescopic one) we gain an additional 17cms in height, positioning an attached camera at about 1.38mts from the ground. Not bad for an equipment that retracts up to 31cm when fully closed.
Two of the legs have leg warmers, however that rubberized material seems a little delicate for intensive use. Certainly not in the same league as the ones on my trusty Manfrotto 055 NAT3. I think they will wear out quite fast. Have to start looking for spares.
The standard ball-head that comes with the equipment (called C10 by the maker) is well machined and with a smooth movement, having both a ball lock knob and a panning base lock knob. However the max load allowed for this rig (4kgs, according to the constructor) seems to me a bit optimistic. This is an equipment clearly aimed to a consumer DSLR kind of camera with a light kit lens and not for the weight of a professional product, such as the Nikon D4. Or even for a D300 or D700 with a heavier Nikkor lens. So you can imagine my surprise when I read on the SIRUI site that this particular ball head has a max. weight load of 15kgs (or 33.1lb). Now... that's optimism.
One thing annoys me, however: you cannot lower the center column. It's fixed on the tripod's base plate. and you will always have those 21cms of metal between the tripod base plate and the head you choose to put on top of it. I think it was John Shaw who once said that a raised center column turns a tripod into a three legged monopod. I'll see in the future how it works under windy conditions. Granted, there's a retractable hook on the tripod's base plate. You can always suspend some weight on it for additional stability, but... come on Sirui... all you needed was to drill a hole and place on it one more twist locker, pretty much similar to the ones on the legs.
By the time I'm writing this, their website is already showing another version of this tripod. This time, without its center column. But it would be more interesting that the center column was there. And that we could use its extension at our own discretion.
After testing it in the field, I'll update this small review. Meanwhile, a small tripod is better than no tripod. And this small buddy seems to be quite alright for the task. Keep on shooting...

Domke Toad 20 waist pack - Review

There are three major ways of transporting our photographic stuff in the field. They are: shoulder packs, backpacks and waist packs. All of the shapes have its pluses and minuses and the "one kind fits all" philosophy is an approach that is quite useless in this area. 
Regardless of the system that we adopt, we have to understand one's decision as the best compromise between weight, load capacity, carrying comfort, ergonomics and durability. Of the three, we can immediately reject the shoulder pack (or shoulder bag). Although being the most user-friendly design of the bunch, its asymmetrical placement over the body for transportation makes it a nightmare for long distance walking. They have their use in photojournalism, in (several) sports photography, in the studio. Ergonomically speaking, shoulder bags are the best of all. By a large margin. Lots of space for stowage, they come in a variety of shapes and sizes in a variation of the concept single body/single compartment. However, as practical as they might be, just imagine yourself in a fifteen mile hike on the mountains with ten kilograms of material suspended from one of your shoulders. 
That leaves us with the last two options: backpacks and waist packs. I'm a big fan of waist packs. For one important reason: they keep your back dry. It might not be important to someone hiking in the desert or in the jungle (out there, you are already wet anyway!). But in the mountains of Madeira island,where you face low temperatures and high humidity in the air in every season other then Summer, being wet is not an option that you should take lightly. But this option forces you to a compromise in... space. With a backpack (particularly for those with double compartment)  you'll always have a small space for a rain jacket, for a snack, for an additional polar fleece. 
With a waist pack you can forget all of it. A water bottle, an energy bar and a few crackers, a Swiss army knife and torch and you are done in terms of survival items for the wild. Not forgetting to mention that, compared to the other two systems described above, you'll always take to the field less equipment due to the smaller size of these packs, what do you gain by using one of them? You gain freedom. 
How?
Easy. All the clothes needed you are already dressing them. You are dressing for the occasion. Not more, not less. Actually, if possible, a little bit for the less. Your rain jacket (your third layer), during the hike goes around your waist. You are walking and feeling hot. Your body is working as a radiator. Let it release all the heat and the sweat, so you always stay dry during walking time. The rain jacket is to be used when stopping, so that you are protected from the cold temperatures... and from rain showers. A pair of light fleece gloves goes to a pocket in the pants when not in use. And the same goes to a fleece hood.
On the waist pack itself you take a medium size DSLR body with 18-55mm lens attached, a 55-200mm and a flash. Add to the mix a handful of needed accessories and a couple of spare batteries and you are done. The tripod, if needed, is transported over your shoulders (military style) and if you opt, instead, for the monopod you get at the same time a hiking stick.
I've told you about freedom, didn't I?
There are several waist packs on the market. From several makers. LowePro, Mountainsmith, Tamrac and Domke are just a few. A few years ago I've decided to buy one of them and, somehow, influenced by the cost factor I've made a choice for the Domke Toad 20. At the time was one of the cheapest on the market and for the price paid I still consider it as a very good equipment in terms of cost/quality.
I bought it in Adorama (www.adorama.com) in July of 2008, by a mere 29.99 USD. And as you can see on the pictures below, there's a lot of bang for the buck.


The general aspect of the Domke Toad 20, on the picture above. A simple but effective design, punctuated by three colours: black, blue and yellow.

The zippers (all them a bit too tight) have yellow rope extensions on them, allowing for the operation with gloved hands. The same applies to the side pockets. The main belt, made with a smooth and silky mesh is easily adjustable and on each side of the main body two adjusting loops assure a snug fit to the body.

The main compartment, in bright yellow, makes all the equipment easily seen even in somehow murky conditions. Velcro dividers in the same color allows for a more personal division of the space inside. However, make no mistake, the space inside is exiguous. In the configuration shown above, the widest part of the compartment accepts a Nikon D40x (or any DSLR with similar size) with 18-55mm attached. The smaller space accepts a medium zoom in upright position or any other extra lens. Both side pockets can also be used to the stowage of accessories. The top cover, opening away from the body (well done Domke) has capacity for thin accessories, so all the small things can be placed there (filters, batteries, cables, cleaning items, etc).


The main compartment is accessible by the front zippered pocket, even if you have the top cover closed.  To fulfill that second option you just have to remove the longest yellow separator, which is connected to the "walls" of the main compartment by velcro stripes. Sadly, this main divider is not "velcroed" to the bottom of the main compartment. Therefore, some small accessories that you might stow on the small front pocket sometimes migrate (due to the walking movements) to the main compartment and you end up looking for them under the camera body or the extra lens. Not a big drama if we pay attention, but can eventually damage paintings, scratch plastics or lenses if we are not aware.

Under the bag we see these two slots that gives this waist pack an additional transport capacity. For that, you'll need two loops (that also come as standard accessories). Although it seems these slots were designed to carry a tripod, I don't feel they are resistant enough for that kind of weight. I use them to carry an additional piece of cloth. And that's about it.

Finally, the spares and accessories, from top to bottom: the all-weather cover, two spare velcro dividers for additional customization, two loops for additional transport capacity and a small mesh bag for carrying the all-weather cover.

Conclusion:
All in all a very nice waist pack. Certain details on it gave me the impression that some inputs from sports and active photographers were taken into account for the development of the product. The (few) minor cons cannot make me forget that this is a very good equipment. Probably, at the time, the best for the price. And, although I upgraded recently for a more recent item, I still look for it when I want to travel light or when I don't need to carry to much stuff. And that's freedom. Because we are only truly free when we give up.
