I can't decide which to buy. The Minolta (manual focus) is cheaper, but the Voigtlander is smaller. So, it comes down to performance. I realize this is an apples and oranges comparison, but I can figure out the SLR vs. RF differences myself. I was just hoping some of the folks here that have used both lenses could tell me something about how they compare. Purely in terms of optical performance, what can you tell me? Anything helps.
