You don’t have to cheat physics to get a much smaller lens with mirrorless. Without the room for the reflex mirror, the rear element of the lens can be much closer to the image plane. This makes it MUCH easier to build a really high quality 50mm or shorter fast lens in a small package. Yes, if they’re Leica, they can be very expensive, but Cosina makes some beautiful lenses under the Voigtlander label that will knock your socks off for less than $500. If you really want to blow your mind, check out the Voigtlander 12mm and 10mm full-frame lenses - try that with your SLR! DSLR’s are at a major disadvantage for focal lengths of 50mm and shorter.
