Hardly possible but they done it: the SL version is more gorgeous than the M39 version, and approximately the same size without counting the hood.I have the cv 75mm f/2.5 in F-mount as well
But that's a pricey lens nowadays. I'll be happy and treasure my M39 version with front focus and all, given I only paid ~200 € for it. The 1-meter MFD pesters me a little, but it's not the optical formula I don't think? They just limited it to 1 meter since that's the limit of M39 focusing standard. SL goes to 0.7 m. Which is funny since they could have reissued an M version with that MFD without touching the formula...
I think, for Nikon, I won't be chasing the 75mm options too hard. It's already too close to 50mm and there are the 85mm lenses instead. Or 80mm. Or 58mm ones, or 60mm... And one can get 70mm with a little help from a 1.4x TC adapter.
