I'm wondering if anyone else is noticing issues using various adapters onto the E-M1 and not being able to mount them? I find the E-M1's weather sealing makes for a very tight fit and that some adapters will just not mount properly on the E-M1 despite working fine on other M43 bodies. I've already had issues with a extension tube and focal reducer adapter. Has anyone figured a way to make them fit if they've experienced these problems? Thanks for any help!
