Yesterday I received a Canonet GIII QL17 that I bought off of eBay. It was advertised as being "as is" from somebody who claimed to not know much about cameras, so I knew it was a bit of a gamble. Anyhow, the camera's mechanically sound, with good metering, shutter action, and film advance. The trouble is that the lens has some fungus. I'm wondering what would be involved in tearing down the lens to clean this out. If it's do-able, I might just treat this as a learning task (I've never done this sort of thing before). If it's likely to be too much of a pain, I'll sell the camera on eBay for parts. Any advice or pointers to Web sites with instructions on how to take apart the lens on one of these cameras? Thanks.
