Look like one happy customer.

Not sure, Mladen.  At first, I thought it was front focusing with the OVF by about 30mm.  But then I looked at the 0.95 Noct at f/0.95 and it was bang on.

I put the difference with the 28 Summilux down to user error.  The two images above are heavily cropped, so I don’t think I have a real problem - happy camper!

Okay, so I set up my M10-D on a tripod, angled at about 45º pretty much at minimum focusing distance, f/1.4.

First with OVF

Then with EVF

What size paper is the test chart printed on?

glad your copy is good!

Can the cold cause the metal to change slightly enough to cause temporary focus issues? I tested this morning and got completely different results. (not because of testing differences, etc). The issue I saw in DC was VERY obvious. Please forgive the less than scientific means. I was doing this in a hurry.

The above looks ok. Now, I slightly different setup and the focus is on the back of the h. The focus appears to be ok but the area of focus is mostly behind the H. Massive crops.

Even with these low rez images I can tell these are considerably off. The OVF is front focusing quite a bit. What's funny is that 99% of users would never know that it existed because in real life external factors (e.g. subject movement) impact focus more. If you look for problems, guess what... you'll find them.
