ALL Lomo LC-A+ cameras
are fully compatible with, and quite happy inside the Lomo LC-A+ KRAB.
In order to use an original Russian-made Lomo LC-A cameras with the KRAB, it must have a metal exposed advance cog on the bottom of the camera. The KRAB’s advance wheel plugs into this cog, and allows you to advance the camera while it’s inside. See the images for reference. If your LC-A does not have this exposed advance cog, then it regrettably cannot be used with the KRAB.
