網路上有不少這類的討論,譬如說:

http://leicarumors.com/2014/01/22/review-using-leica-m-lenses-on-the-36mp-sony-a7r-mirrorless-camera.aspx/

這類運用的最大問題在於shading或lens cast。
解決辦法:
CornerFix https://sites.google.com/site/cornerfix/ (免費)
C1C Universal Lens Calibrator 只能用在Capture One Pro (付費)
比較可行的辦法似乎是:
Adobe DNG Flat Field plug-in (免費)
