ZY Optics has released a Canon EF mount version of the Mitakon Speedmaster 50mm f/0.95 lens. This isn’t just slapping a new mount onto their existing Mitakon Speedmaster 50mm f/0.95 III for Nikon Z, Canon RF and Sony FE mounts, though. This is an entirely new lens designed specifically for Canon DSLRs.
According to the press release, ZY Optics says this is currently the world’s only f/0.95 lens designed specifically for full-frame DSLRs. Sure, there may be some old ones out there, but none of those are still in production and a lot of the new ones coming out are designed for mirrorless only. Oh, the price? Yeah, that’s going to be a mere $799.

The outward differences are quite striking between the new 50mm f/0.95 for EF (left) vs the existing 50mm f/0.95 for mirrorless (right)
While there are obvious differences in the exterior of the lens, there are also differences internally, too, with a completely new optical formula. The mirrorless version of the lens contains 10 elements in 7 groups while the EF version is comprised from 12 elements in 6 groups.

Samples supplied to us by ZY Optics using the lens show that it renders rather well. Being able to shoot full length portraits (even in landscape orientation!) with such a shallow depth of field is a nice ability to have, and usually limited to medium and large format.
The lens has an 11 blade aperture to help create that perfect nicely diffused spherical bokeh, with an 82mm filter thread to help minimise the risk of vignetting. IT has an all-metal housing for maximum durability with one High Refractive Index element and five Ultra-low Dispersion elements to minimise chromatic aberration.
Unfortunately, this lens won’t become available in a Nikon F mount version. ZY Optics says that this is impossible because the rear element is just too big for the F mount to handle. Which is a shame, because as soon as I saw the press release I was like “oooh!” and then I read a bit more and it became “awww!”. But still, if you’re a Canon shooter, have at it!
The ZY Optics Mitakon Speedmaster 50mm f/0.95 for Canon EF is available to buy now for $799 from the ZY Optics website.
