I've been reading about how the 14 Panasonic could have better micro contrast compared to the 12mm. I have the 14mm now and I want to compare its micro contrast ability to a lens know to better it. I have the Oly 45 and 75 on loan now and I was wondering if this can be a sensible comparison of micro contrast. Two questions: 1. Can I even compare? 2. How should I do it? Thanks a million!
