Mir-47 20mm f/2.5

Sharp, works nice I USED IT during weedinis in my lumix g7 videos, i really love the f1.7. Now I dont have to use high ISO. The only issues is sometime it lost the AF and takes a lot time to get it back. My 14-42 is fast but this 20mm (in low light) takes lot of time. Sometimes i change it to manual focus.

A Nice Compact 20mm Prime Lens It's sharp, as most simple primes in this focal range seem to be. A good, all purpose walking around lens for small M43 cameras. Some say the autofocus is a little slow to focus but it's as fast as it needs to be for most uses.

Favorite lens for years Best pancake, one of the sharpest lenses I’ve ever had. It’s not the fastest to focus because of the motor, but it’s worth it if. Then I got the Ef 40mm 2.8, which is also awesome, sharp and slow as well. Just waiting for FE and R mount pancakes. I love pancakes.
