I’ll be covering the new Zeiss lenses for Sony NEX and Fuji X sometime in late April / early May.
My plan is to test both on the 24-megapixel Sony NEX-7 for it higher resolution, or the NEX-9 or whatever newer and improved top-end NEX becomes available.
The lenses will also be offered for Fuji X mount. But at 16 megapixels and with sensor artifacts, 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.
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 lack of need to design around a DSLR mirrorbox.
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.
