Sigma 35mm f/1.2 FE Lens Rumored Specs:
Lot of HR elements in construction, record low aberrations
Record MTF of any FF lens at F1.2
Ultra fast and silent AF, made also for video
This Sigma 35mm f/1.2 FE Lens will be the first lens designed specifically for Sony Full Frame mirrorless from Sigma. The impressively fast f/1.2 maximum aperture affords a great degree of control over depth of field for isolating subjects and producing desirable selective focus effects. The size of Sigma FE 35mm lens is expected to be between Zeiss FE 35mm f/1.4 lens and Zeiss FE 35mm f/2.8 lens.
The official announcement will probably in July. Stay tuned for more info.
