One reviewer downgraded this bag to 3 stars because he couldn't fit all his kit in it ! This reminds me of the time when my wife bought me an Irish tie and, keeping a straight face, I took it back a week later and asked for a refund because it was too tight. Hopefully, this review will be helpful if not amusing.
The bag now contains an Olympus EPL2 camera with its kit lens attached, a 40-150 (80-300 in 35mm speak) lens with lens hood, 2 filters, a remote release, 2 spare batteries, an electronic viewfinder and a Lastolite reflective sheet. The only thing I cannot fit in is a small dedicated Metz flashgun but the built in gun is normally enough unless I am repeatedly using flash.
It gives adequate protection and lets me access the camera quickly. Over protection can restrict access and there are no prizes for missing shots. It's a well made bag giving protection to cameras on the move which I can thoroughly recommend.
