A leaked comparison image between the Sony and Canon versions of their mirrorless 50mm f/1.2 lenses shows the upcoming Sony release will be about the same size (perhaps a shade longer, and a smidge thinner) as the canon offering. Sony Alpha Rumors indicates it has been told that the Sony lens weighs 172 grams less (18 percent) as well.
Meanwhile, Nokishita has the initial pricing, coming in at $2,198, which is 4.4 percent cheaper than the Canon version.
The lens is rumored to be released today, showcasing the adequacy of Sony’s E-mount system, which some critics have called “narrow-necked” to the degree that it negatively affects lens design flexibility. Sigma already proved that f/1.2 aperture lenses could be made on the mount, with it’s extremely-well-regarded 35mm f/1.2 Art lens, which has yet to be matched.
