I bought a 20.7mm lens 6 months after I bought a Micro Four Thirds (M4/3). I'm not the type that cares much about image quality, but considering the price and size, it's pretty good. There are many people who say that the AF is slow, but it seems faster than the GR2 I used before. It's like the speed of a mid-level DSLR lens. I'm very satisfied with the pictures I take with the 20.7mm lens because they come out well.
