Re: 7mm on M3

Can you post a picture of your setup? The issues you are having with infinity focus may be due to the thickness of the adapter. The adapter should be no thicker than 1.25mm.

I get the impression he's talking of the FourThirds version rather than M43 ??

Those had a somewhat longer flange distance!

Yes, she (=me) spoke of four-thirds not micro-four-thirds. And I don't have an issue with infinity, but found it remarkable that focusing (internal) had so much effect on image quality for objects being not close at all.
