Originally posted by Winder I have not seen any other source indicating that Sony lacks tonal range compared to Canon. Are there some other sources showing this same issue? Was he shooting in compressed RAW? There are several variable and without being able to read Russian its had for me to comment one way or the other. It may very well be true. I have read quite a few comparisons and this has not come up.
His point was that whereas Canon has smooth tonal transition, Sony has a kind of a border between 2 different colours. Kind of that. Here is
another his post where he compares Sony A7ii and Sigma Quattro H (look at the lips - there is that smoothness in Sigma case, though lenses used are different - Sigma Art vs Samyang). Pictures here are his own.
About that guy - as far as I understand he has owned and / or tested Canons 5D something and 5DSR (his current camera), Pentaxes 645D and K1 (liked both, used to own 645D), Sony A7ii (sold because pics looked "cheap" for him) and Sigma Quattro H (tested, mixed feelings).
In the first quoted post pics are from Internet. In comments some Sony owner wrote the same - that perhaps they were shot with compressed RAW and that was the point.
Really sorry for Russian - just it's the only source where I've read about that issue in any language.
