I am looking for a case for my PEN e-p1 body with Panasonic Lumix 20mm F1.7. I am a very casual photographer so I don't need a bag - I need a sturdy pouch to protect my camera, which I throw into my purse or backpack. I was looking at Billingham pouches, namely Avea 5, 6 and Delta End Pockets, but I am not sure if my camera will fit nicely into it. I don't want it too big (I don't need any room for accessories) and obviously not too small because I can only buy online. Does anyone have use any of the pouches for their M4/3 cameras? Thank you!
