Since the Kata DB-453 only holds up to two lenses in the camera compartment, it may not be for all users. I tend to travel lighter than most so I find the setup ideal. This bag is perfect for those looking for a messenger style bag to carry their DSLR, kit lens, and a smaller primes lens. Once the camera insert is full, there is sufficient room on the side for a flash unit or a small sack lunch.
Overall, I think the Kata DB-453 is a great bag and I recommend it to anyone that needs a smaller pack for short photo outings. The bag is well made, water resistant, and very easy to clean. With the camera insert removed, it is even wide enough to accommodate a 10 or 11-inch netbook to double as a small computer bag.
