I use the camera bag for my Sony NEX. Everything you need fits in well. I have worked with the Kalahari now filter and both lenses SEL (WW and 18-55) and SD cards always on man and a tripod I clamp the retaining tabs. Nevertheless, one notices the bag while wearing little and it is robust and of high quality.
As an idea: a simple plastic cover for sudden rain shower would be great. Costs almost nothing in production. I take a garbage bag so far.
