Wow a year goes by fast. In December of 2009 I posted some information about bagging your camera. Later that month I purchased a Kata 3n1 20 bag. After a year I have fond it to be a well built bag that protects my camera well. It can be used as a sling or as a back pack bag. The padding is great and I have hiked a couple of times in the rain and my equipment stayed safe and dry. Where the bag falls short is when I carry my 4 lens, and my filters and then want to take my Fong light diffuser, it gets crowded. Currently I have a Nikon d200, 700300 nikon lens, 105 Tokina 2.8 lens, nikon 18-200 lens and nikon 50mm 1.8 lens, nikons 600 flash, battery charger, extra battery, memory cards, 3 lens filters, and my Gary Fong, diffuser for my flash, an extra pair of glasses, and a very small flash light. There is not room for more. I would recommend the bag and the newest version with a couple of cool improvements can be found here http://www.amazon.com/Kata-KT-D-3N1-20-Sling-Backpack/dp/B001BP7YFM/ref=sr_1_1?ie=UTF8&qid=1297371343&sr=8-1 or http://www.bhphotovideo.com/bnh/controller/home?O=&Ntt=Kata+3n1-20&A=endecaSearch&InitialSearch=yes&Q=&N=0
