EF-M 50mm f/1.2 lenses

While I’m a long-time Canon APS-C user with EF and EF-S lenses, I am a relatively new Canon M50 MKII user. I’m really looking for the size & weight reductions with the M system for hiking, backpacking, and cycling. I’ve acquired a few EF-M mount lenses.

I’m trying to make sense of the 50mm lens (80mm in 35mm equivalent) offers.

There is a TTArtisan 50mm f/1.2 lens (manual focus, 10 blade diaphragm) for about $100 and a Rokinon 50mm f/1.2 (manual focus, 9 blade diaphragm) for $500. Anyone with experience with both of these? I’m trying to understand what the Rokinon bring to the party that is worth $400 more — Is the actual quality of the lens that different in terms of glass? I must be missing something…

Thanks in advance!

PS I also know there is a 56mm f/1.4 offer from Sigma — but this is a different lens in terms of focal length and it has auto-focus. I like Sigma glass a lot, but looking at all the options.

To me, the difference between AF and MF is much more critical than between f/1.2 and f/1.4 or between 50mm and 56mm. Sigma is top-notch in many ways. I believe there is no reason to choose Rokinon over Sigma. However, the reason for TTartisan is its price alone.

Thanks for the input. After reviewing these and some others, I decided on the Sigma 56mm. I’ve always had great luck with Sigma glass and think it will serve me here as well.

You won't be disappointed, the 56mm is fantastic.
