Sigma’s upcoming 35mm f/1.4 designed specifically for mirrorless will be only one centimeter shorter than its 35mm f/1.4 Art designed for DSLRs and weigh only 100 grams less.
Nokishita reports that its reproduction ratio will be 1:5.4, which gives it about a middling 19 percent magnification rate for close-ups. It has a boatload of lens elements and groups, as would be expected from the fir, with the new standard number of aperture blades in the bokeh-seeking market: 11.
The filter diameter is the same at 67mm.
All in all, the specs do not stand out, especially in the quite competitive market for high-end 35mm lenses. A critical question will be mount choices. If this becomes available in RF mount, Sigma will beat Canon to the OEM punch. Canon’s 35mm prime offering is limited to the budget- and macro-minded RF 35mm f/1.8.
