In researching the 28mm (both the older D model and newer LS) I was told that the 28 wouldn’t work well with an 80-megapixel back. Soft corners and color problems were just some of the concerns mentioned. I had to see for myself.
So there you have it. The 28mm does work well with an 80-megapixel digital back due in large part to the improvements of the software of Capture One Pro.
