Re: Poll: what is your preference? 24-70 II @28mm or Zeiss 2/28 ZF

I am contemplating the 2/25 as a replacement for the 2.8/25 to boost overall sharpness in this FL. The Dig Pic hasn't shot a test chart for the 2.8/25 ZF because it appears they have limited their testing to the ZE versions. The 2.8/25 is not available in the ZE version so I cannot say with any precision just how much better an upgrade would be.

I don't have the 25/2, but from what I've heard it is as good as the 21/2.8. It has very low field curvature, so planar subject will appear with sharper corners. I would not trust just a resolution chart test here - with UWA lenses the charts are shot from very short distance and the performance may differ from infinity.

See the link above. The difference in sharpness between the Sig & the 2/35mm Zeiss which is used in my comparison is minimal to non-existent in certain zones. The CA in the Zeiss image is significant even at f8 but removable for the most part. For IQ, with sharpness being a virtual dead-heat (in the Digital Pic comparison at least), I would think the tilt would go to the Zeiss for its character (color and microcontrast) and operationally to the Sigma for being AF.

Did you have a chance to check out the ZE 35/1.4? It has beautiful bokeh wide open and the same clarity and micro contrast as the 35/2 when stopped down. It has better corrected aberrations and less vignetting and compares favorably to the Sigma in these parameters.
