GAS got me again! I just bought a black Canonet III QL17 and I need some info. Item 220762480826 on the bay. The seller says the camera is in great user shape (but a bit brassy) but I assumed that I would have to send it in for a CLA, new seals, and a meter adjustment. 1. Who is the go-to repair person when it comes to servicing the QL17? Can they adjust the meter to use alkaline or siver oxide batteries? 2. Anyone know where I can get the proper lens hood? I've seen a listing for a Hood 4 and a Hood 5 but I'm not sure if both will work with the QL17. Which one is the best shade to get? This will be used with B&W film with a yellow filter - HP-5 of course!
