Just picked up a V35 (that was heading to landfill...) It works, and am currently giving it a clean. I've found a French manual and a few informative sites but I can't see how to remove the lens. I am assuming it's just a simple screw mount, but am reluctant to force anything yet ;-) Can some one please confirm the best way to remove the lens? Also, I only print B&W but there's a colour head. I am assuming you can still use that for B&W but I just need to find the appropriate amounts to dial in that match equiv multigrade filters? Thanks very much.
