Summary: Couple of notes about me: I'm a outdoor fanatic, traveler and bag nut. Combining the 3 and you have someone that always like to be prepared but also likes to pack as lightly and compactly as possible. Hence my choice of the smallest 3N1, the 10, for my DSLR kit which happens to be: D90, 18-105VR, 70-300VR, 35/2, 50/1.8, and SB600 (all Nikon). I have configured the main compartment to fit ALL of the above, and with sling quick-draw with ANY of the 4 lenses attached.
Summary: Functionality, this bag is fantastic. You have the benefit of wearing it as a right or left handed sling or normal 2 strap backpack. Enough room for body and 2 medium length lenses. Look is great, contruction great. Unfortunately, this bag is a bit too small for my set up and in hindsight would have liked to have gone with another bag. I have a canon 40d body w/ battery grip so the camera is a bit of a tight fit in the pouch.
Pros: Adjustable Harness, Comfortable, Easily Accessible Equipment, Lightweight, Strong Construction
Summary: I needed a new home for my DSLR and accessories and the Kata 3-n-1 10 caught my eye as I was walking around a photo show. I was attracted to the odd looks as I had been on the look out for a bag that did not resemble a camera bag. At the show the bag was on offer for £60 so I decided to get it. The bag has a reinforced front for protection.
Pros: Stylish. well made, holds more than you would think, excellent adaptable strap system
Cons: Could be sealed tighter to avoid dust getting in though to date i have not had an issue
