Looking for a suitable, small bag for my new RX100M3 I stumbled across the Crumpler Light Delight LD100-001 100. I ordered it and am very satisfied. The camera fits perfectly in the pocket: Not too tight, they can be easily and without tuft pull out and push in and on the other hand not too far, the camera has no significant play and is well enclosed by the padded case. Anyone looking for a zippered pocket for RX100M3 (RX 100 M3 / MK III), can be accessed here.
