I'm in the market for a new high MP camera. Mostly for archival work. I have used a 5DSR in the past, with a 24-70 f2.8L II, which was not the right lens (field curvature caused problems, but I didn't have enough space to use a 100mm macro, or 85mm). Seems like the time to go mirrorless, but with which lens? The RF 35mm macro? Any info on the field curvature for that lens, or field curvature on the new RF lenses in general? (Has mirrorless helped field curvature?) And when might we guess the new high MP body will arrive? I could definitely use more than 50mp.
