I have both the Canon Q 1.7 and a Retina IIIC big.

The Canon is much better with color than the Retina.

There are only a few folks left who know how to work on a Retina Shutter.

Me too.. experienced with both. But I would respectfully submit that there are many, including me, who would dispute these two statements. Every Retina I have used has ALWAYS been better with color than any fixed-lens Canon rangefinder. Yours must be a spectacular example if it is better than the Retina.

The shutter on the Retina IIIc and C (as well as the IIc and C) is your run-of-the-mill Synchro Compur. Nothing special that any camera repair person can't deal with effectively. What is difficult for many are the interlocks in the body!
