I have a small collection of these compact "backpacker/adventurer cameras". Olympus XA and X2, the Minox 35, etc.....The little Rollei35 tends to be pretty heavy. There are other really compact Olympus cameras too that are a bit newer and auto-focus.
PM me if interested in the XA, X2 or the Minox. I'd rather sell to a hiker than a camera reseller. All are working but show wear. The Minox was recently CLA'd and has the modern battery adapter.
