SLRLensReview test of Zeiss Distagon 35mm f/1.4


After perhaps reading a not so positive review from LensTip.com, here is a different review by SLRLensReview.com. The conclusion from SLRLensReview is very positive, in particular the color fringing issue highlighted in LensTip.com's review now appears different under the hands of SLRLensReview:
The Imatest measure lateral CA at ~1.5px at f/1.4 around borders and at ~1px through the rest of the aperture settings. It's not too bad, and the CA will be visible only under high magnification. You would also need to deal with occasional longitudinal CA in out of focus areas, which can also be observed in some of the sample shots below, but overall, Distagon performs on par, maybe even slightly better than other 35/1.4 lenses I've tried in the past, and so I would say that the color handling in this lens is top notch.
I wonder if there was a sample discrepancy between the lenses in this review and the previous one. However, I have to say that the CA test at SLRLensReview isn't very extensive, so they might not have teased out as much fringing as LensTip.com did.

Edit: Thanks to Markus (from photozone.defor pointing out my wrong understanding of the two different CA tested by LensTip and SLRLensReview.
To reiterate what Markus points out in the comment. The CA found to be high in LensTip's review is longitudinal CA, the direction transverses to the focus plane, while the CA found to be good in SLRLensReview is lateral CA, the direction in the focus plane. Hence, these are CA in different directions.

  1. Longitudinal CA, aka bokeh fringing (found to be high by lenstip) and lateral CAs (tested by SLRlensreview) are two very different things.
