I am hoping to see these two beauties soon by May 3rd for testing.
My plan is to test both on the 24-megapixel Sony NEX-7 for its higher resolution.
The lenses will also be available in Fuji X mount. But at 16 megapixels and with sensor artifacts that confuse evaluation with some subjects, the Fuji X platform is less attractive for testing lens performance, though ergonomically I prefer the Fuji X body style over NEX.
Both the 12mm f/2.8 and 32mm f/1.8 will be offered from Zeiss, but the existing 24mm f/1.8 remains a Sony product:
The 1.8/24 is sold directly by Sony and they will continue to manage the product.
The 12/2.8 and 32/1.8 are both autofocus and have won the IF Product Design Award.
Zeiss Toiut 12mm f/2.8 Distagon
Equivalent to an ~18mm lens on a full frame camera, this is an ultra-wide angle design. My expectation is for it to outperform most full-frame designs by dint of being newly designed and optimized for the APS-C format and no need to design around an DSLR mirror box.
Zeiss Toiut 32mm f/1.8 Planar
Equivalent to an ~49mm lens on a full frame camera, this is a moderately fast normal lens. The f/1.8 aperture and new design give some hope for a very high performance design, with my wish being for a flat field and no focus shift.
