Official: Voigtlander 15mm f/4.5 III E-mount
OK I screwed up the first test posted yesterday! Sorry!!! I forgot to set the A7R2 back to full frame mode after using it in APS-C mode to test my Zeiss Touit 12mm f/2.8 lens.
So the corner crops looked much better in APS-C mode than they do in full frame (go figure)
I re-tested the lenses this morning at the same scene. The morning light is a bit harsher so bare with that but I can easily tell that the CV15 III VM has softer corners than both the FE16-35 f/4 and the Loxia 2.8/21. The Loxia is clearly the winner here with the cleanest corners of all the lenses tested.
I did not have any Lens Corrections set in LR so Vignetting and Chromatic Aberrations are not corrected. These are straight RAW files with no post-processing other than a + 50 bump in LR Exposure slider too each shoot due to the harsher contrast. Sharpening is my standard RAW sharpening at Amount = 50; Radius 0.8; Detail 50; masking 0.
My CV 15 III does not look as good as "Choppy" in the extreme corners maybe in the center and the rest of the frame? I do think it is better than some of the other CV 15III's posted here but still a little disappointing non the less. I will look forward to seeing how the Batis 18mm tests compared to the FE16-35 and the Loxia 21. Now I'm not sure if I want to sell the CV15III VM and try to get a good performing native E-mount version or just stick with this one and use it on my A6300 as a nice 22.5mm lens to go along with my Touit 12mm lens (18mm)?
