I have been using a case logic camera backpack for two years now. It can hold my cameras and lenses well, but after repeated use I have found out one sever limitation of this (or this "type of backpacks"). So I am looking for something "different".
Ok, so what is the limitation? To be specific I use the Case Logic DCB-309 model which can be seen herehttp://www.amazon.com/Case-Logic-DCB-309-Camera-Backpack/dp/B004JMZPK0/ref=sr_1_6?ie=UTF8&qid=1373265907&sr=8-6&keywords=case+logic+camera+backpack.
Now this bag can carry all my gear when I am going from one place to another in car, or aeroplane or some vehicle. The problem is when I am walking around. But its entire frontal wall/side comes off (except the bottom hinge part) when the zipper is opened to access the camera. So If I am carrying two cameras one at the top end of the bag and another at the bottom then to access the camera that is at the bottom I have to open the entire bag. This creates lots of problems for me. And I do not like it.
Therefore I am looking for something like a lowepro Fastpack or case logic kilowatt ksb 102 (see here http://www.amazon.com/Case-Logic-Kilowatt-KSB-102-Backpack/dp/B009M3UULK/ref=sr_1_4?ie=UTF8&qid=1373265542&sr=8-4&keywords=pro+dslr+back+pack
). Now each of these bags (and may be some others) has a side opening system. I can keep a camera at the bottom of the bag and take it out sideways. So far so good. But my issue I want to carry a second camera in the same bag - in the top compartment which opens from top and front without opening the bottom compartment. My question is have any of you used these back packs in this particular way? Can the top compartment hold a second camera body - of course not with a tele lens but may be with a wide angle or walkaround zoom (say canon 17-55)? The reviews on amazon does not specificially address this issue. Otherwise do any of you know/have used any other bag with this particular facility - one side open compartment at the bottom, and one top/fron open compartment at the top - for two cameras?
Thank you for your time and patience - the post became too long.
