Also picked up a 65/8 and GL690 at the same time. Bad GAS attack. But the lens was billed as a copy in unusually good condition for its age, and the camera was a cheap, dusty and rusty old thing which I intended to keep as a backup...
Turns out the performance of the 65 was terrible (a chronic condition among 'overhauled' or 'rebuilt' WA lenses, it seems) and I sent it back, while repainting and cleaning out the top plate of the GL690 rendered a camera that works better (dark slide release is snappy & strong) and has a clearer viewfinder than my original G690BLP. The front shutter release is pretty great, too.
Now I just need to get my hands on a good wide angle lens. I've got another 65/8 on the way, I just wonder if it will be any better. Everything but the standard lens for these things seems hard to come by, and what seems to be available at the moment isn't in great condition.
