Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - mst - 11-01-2017 A marvel. A pity it doesn't have AF http://www.opticallimits.com/nikon_ff/1021-zeisszf13520ff -- Markus Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - JJ_SO - 11-02-2017 And a marvel with AF would look like this: Original size I know, different situations and mine was taken at ISO 64 and a bit more MP - but I don't see much of a difference. However, I haven't looked deep into it and if it comes to bokeh fringing, the Zeiss might be better. But altogether: Keep your Zeiss, I'll stick with Sigma. Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - JJ_SO - 11-02-2017 I was just looking at the price of the Apo Sonnar. Some dealers offer instead the Milvus 135/2 and put in brackets (App-Sonnar). Are the lenses, except the stylish, but ugly finish of the Milvus, identical? Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - Brightcolours - 11-02-2017 Yes, they are the same optics. Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - JJ_SO - 11-02-2017 Thanks. Now I know what the new design costs... Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - Guest - 11-02-2017 Why is the vignetting score based off of the camera's jpg instead of the raw file ? Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - Guest - 11-02-2017 Maybe Marcus will repeat the test with the sigma for comparison. It was a 5* lens on the canon test. Quote:And a marvel with AF would look like this: Next lens review: Zeiss APO Sonnar T* 135mm f/2.0 ZF.2 (FX) - Brightcolours - 11-03-2017 I think that the software takes JPEGs, and how do you create JPEGs from different cameras with exactly the same tonal curve? Even using the same RAW converter does not give the same tonal curves.

You need to set a baseline at some point and use it as a reference point for the system. In terms of vignetting, we decided on using the standard JPGs a camera produces, since they can just bet fed into Imatest without any further work. RAWs would need to be converted to JPGs first, with a defined set of parameters to have comparable results. That's actually the same thing a camera does already, so why invest more work than necessary. |
