Not sure if this is normal at wide end. But I see some purple blob (right side of the big tree) similar to the one from Pana 7-14 on E-M5. Not much and did not notice until I downloaded the file to computer. Any one saw this before ? Shot at 12 mm, f5.6, iso200, 1/640 sec. No edits except for resizing on export from lightroom. Edit : This is the jpeg convert from raw, exported from lightroom.
