I currently have the official Olympus mini-backpack to hold my E-PL1. It works fine, but unfortunately can't use it as a sling bag. A lot of other bags are too big for m4/3 cameras.
I'm planning to go on a cruise and am looking for a sling bag and/or leather case with strap that would be faster to get the camera in and out. I don't want a full leather case that encloses the kit lens because I modified my kit lens with a hood. So my camera won't fit in any of those full cases. Plus I also have the MMF-2 adapter and 40-150mm zoom.
Would it be best to get just a leather half-case with sling strap, and put that in a sling bag? Will I look like a dork, carrying a sling bag and camera everywhere on the ship?
