Nice lens, a pleasant surprise for Meike. Thanks for testing it! You wrote that the "Equiv. aperture (full-format)" is f/4. For an APS-C lens this would be correct but this lens is for MFT-mount. So the equivalent aperture in this case should be f/5.6, right?

You are absolutely correct. Haven't tested MFT in a while so I forgot already. I'm getting old. ;-)

I hope OM will release the E-M5 IV soon. The II is getting a little long in the tooth.
