The focal reducer is no longer producing crisp photos as it once was. I've tried a couple different lenses. And it's not the camera as the GM1 is doing great with the hollow adapters. Does anyone know how I should screw this adapter to make it work again? I kind of like using my 50/1.7 as a 35/1.2...a FL near which m4/3s doesn't have much to choose from.
