Not fast : granted. Small package : granted. Only pretty good : not granted. The DA21 is the lens that gives me the richest tones, the smoothest textures, and the most even results across the frame. It's very sharp, though not my sharpest (the FA50 macro is) but IQ is not only linked to sharpness.
Even non-initiates can spot the shots I take with that lens . I often get comments like "wow, that's a great picture!" when the composition is only average, because the colours are so good.
Originally posted by axl FOV of 24 mm on APSC is great and suits me a lot, I prefer it to 31 by mile in this respect.
You will not find dramatic differences between the 21, 24 and 31. If you find the FOV not too your liking and the bulkiness to cumbersome, you have part of your answer. Those three lenses are different but IQ-wise, they will be near enough. Decide by considering FOV, size, handling, and your own shoting style.
