I took my Daughter to the Skating Rink today, decided it's a good place to bring some Fast lenses. And the two fast lenses that have been waiting for comparison are the Canon 50mm F0.95 for the Canon 7 and the TTArtisans 50mm F0.95 for M-Mount. I have adapters to use both on my Nikon Z5. The latter- I've used mostly on my M Monochrom. I use a color contrast filter, usually a 1-stop Yellow Y48. Used with a Rangefinder camera: I can get it well calibrated for "about" 1meter to infinity. Anything closer will produce back-focus, which needs to be compensated. With the RF- means shifting the focus closer. With Mirrorless: No Problem. If you get this lens- be aware. The Canon 50/0.95- mine is perfect on the Canon 7, close-up to infinity. I am not going to convert it to M-Mount. But- for $40 or so, bought a Canon 7 breech mount to Nikon Z. It's great.
With the Canon 50/0.95, all shots wide-open. It was Dark. I can focus the M9 in these conditions, but the Z5 produces a higher keeper rate. My daughter is skating past me. Just Move the focus ring and keep the Red Highlights on, take picture. Easy. ISO 6400.

I will never complain about the colors on the TTArtisans 50/0.95 again. TTArt 50/0.95, wide-open.

She moved. I picked these out as they are relatively close in composure.
