I have a camera backpack where the bottom half has a camera insert, and the top half is a general purpose section.
You can also fold down the general section, and zip it in place, to turn it into a shoulder bag for just the camera gear.
The problem is, the extra bulk of that unused section folded down means it's actually pretty poor as a shoulder bag, so I never us it that way, and as a camera bag it's fine when lightly loaded (A6000 16-50, 55-210 and 50 f/1.8, plus assorted bits and pieces), and the top section is used for semi-bulky but relatively light bits, such as a fleece, but gets uncomfortable if you put too much weight in it.
Bigger bags need correspondingly larger and more padded backs, straps, etc - with waist belts & sternum straps at the higher end, which would be just XS weight on a small bag.
There are a huge range of bags available these days - the reason why variable size bags aren't widely available is that, in most situations, a fixed size bag will do the job better for most people. |
