Hi, I'm trying to remove the rear element of the taking lens on my 124G to clean what looks worryingly like fungus. I've posted on another forum and have been told it should simply unscrew, and I even emailed Mark Hama and got the same response. The problem is I've tried sticking my fingers/thumbs down there and twisting the lens barrel out and it won't move. Actually since there is no space between the barrel and the walls of the inside of the camera all I can do is get two digits inside the lens barrel and attempt to turn it, and I can't see how that would actually succeed in unscrewing the lens unless it was particularly loose... Anyway I'm here hoping for a second opinion... has anyone ever removed the back of the taking lens on a 124 or 124G? If so, how did you do it? Thanks in advance for your replies.
