Lenstip found LoCA exisiting but nothing to carp of. In their samples (of ghosting and flare) I didn't see so much of magenta borders although the sources for that phenomenon were clearly present.

 

I really don't know what to believe. The pictures at DPReview for my taste have too much magenta in it - but then, 100% of the 42 MP sensor still shows less CA than I am used to for the 85/1.4G

 

Lensrentals didn't check MTF now. On this side and on distortion/vignetting I consider myself as more tolerant than against LoCA. Depending how much highlights are involved I can see the magenta tint aready before I enlarge the picture.

 

Plus, some of Lensrentals sample pictures - mainly the beauty shots - show a quite impressive sharpness while others in lowlight conditions are much less impressive. So, if it comes to lowlight and I have to bite high ISO and / or slow shutterspeeds while aperture is already wide open, what will be left of all the nice resolution numbers?

 

And more provocative: While the performance of the Sigma might be super or excellent in studio conditions with low ISO and fast flash, will the pictures of the Tamron with switched on VC be much worse - or maybe even better?

 

Pity, there's no decent rental supplier in Switzerland.
