Good case for low money

I have a system camera Olympus PEN E-PL7. The fit with the standard zoom 14-42 loosely in the bag. The small Austeckblitz, the data cable, a second card, spare battery and a cloth also still fit into it. Is not enough space for an extra lens. The focus is down (pocket tilts even when empty is not) and the strap is long enough. Unfortunately, the zipper up only a zipper - two would be nice - can be better open.
I wanted a small, lightweight bag slung go not applying too thick - that's it!

25/02/2015 - Another supplement. I have now placed the following in your pocket:
Olympus Pen E-PL7 with shoulder strap and M.Zuiko 14-42mm 1: 3.5-5.6 (the kit lens with manual zoom)
Telephoto zoom M.Zuiko 40-150mm 1: 4-5.6 R, compact flash, spare battery, data cable, close-up lens 58mm, spare SD card and a fabric handkerchief.

The Tele is down across, about the handkerchief and on top of the camera. Next to the lens is still room for the compact flash. Knapp, but it fits. The rest is divided among the various niches and pockets. I still do the original pen pocket here - can not keep up ...

For my pen highly recommended!
