Using Sony A7R2, I tested VM Ultron 28mm F2 II
(July 9, 2021 Bowen Lake Park, Spartanburg, SC)
After using this, I sold out Leica Elmarit-R 28mm V2 E55 and other all 28mm MF
including Pentax K 28mm F3,5 and Nikon 28mm F1.4 E and etc.
I think new VM 28m f2 APO would be better or slightly sharper image at edge.
almost no editing except Luminar Neo noiseless
