This was interesting. I have a 1971 vintage 500C (M) transition period camera with a pre T* coated 80.
I hooked the CFV50II back up to it and the results were surprising. The focusing screen in the body is a split image but not a brightscreen or acute matte. I was still able to get reasonably accurate focus. It's cool to have this option on a vintage camera.
I agree. I looked at them when they first came out and really came close. About a year ago I traded a lens for a 907/50 kit and it's been useful and fun.
