My currently camera bag is rapidly biting the dust. Apparently two years of photography is rough enough to destroy mil-spec PALS pouches designed for war zones.
When I go on location for a serious shoot, I'm normally toting nearly everything I own - quite a bit of "extra" gear. I'm a disciple of backups and Plan Bs, so when I load all the way up, I'm carrying the following:
-Canon 60D with battery grip (usually on a homemade sling, but a quick-access way to store it is a definite plus for rainy days)
-Canon 28-135mm f3.5-5.6 USM
-Canon 20mm f2.8 USM
-Canon 50mm f2.8 USM
-Canon 100mm f2.0 USM
-Canon 70-200mm f2.8L (don't own this yet, but I'm planning for it)
-Two Canon 580EX II Speedlites
-Two Bolt flash battery packs (eight AAs apiece)
-Three-Legged Thing Jack tripod with Manfrotto ball head (largish travel tripod)
-Four different small flash modifiers (all pack flat)
-Three Pocket Wizard Flex TT5 radios
-Smorgasbord of spare batteries (around 24 AAs and various coin cells)
-When traveling, I add chargers for everything and a tiny laptop for backup
Obviously carrying this much gear means the pack will never be terribly light or compact. Moving away from primes would obviously shed quite a bit of weight, but that's just crazy talk.
The main requirements are lasting several years, allowing rapid camera access (sling or convertible packs preferred), and providing good rain and impact protection. So far, the winner is Kata's 3N1-35 PL, but what are your preferences?
Ideally, I'd like to have one pack to cover all uses, but for run-and-gun shoots, something light with rapid access seems appropriate. On that note, I'm looking at a photo belt system or small sling pack. Enough to hold two lenses (one telephoto zoom, one wide-angle zoom or prime), a flash with battery pack, and a small selection of accessories. I can look at reviews and product descriptions until my eyeballs rot, but frankly, I find the opinions here far more accurate and trustworthy than any retailers' site. What works for you guys?
