Having a bagful of the various Yashica Y/C mount lenses, I've often wondered if there's a comprehensive list of just what all the various configurations are. I've got 50mm in a number of aperture designations, 1.4, 1.7, 1.9, 2.0 collected over the years from the bay as afterthoughts to hunting down particular body parts.
Frankly, they're all decent lenses. And since most of my shooting is at f/8 or smaller, the low end doesn't offer me any more light.
So, how many configurations are there of these lenses, and what's the differences? Someone got a comprehensive guide?
