Hi Rick,

First off, congratulations on the new lens.

Regarding Reikans. In my experience the "scores" are very sensitive to a number of factors. I got to the point where I would only compare the numerical scores if shot on the same day with the same lighting, same distance to target, and exact same orientation of the lens to target. Even then, there is a "+/-" factor to the numbers as with the same set up I'd get slight different results with the same lens in repeat tests.

As your Mk 1 is already out of your hands, that is no longer an option. So, I would fall back on looking at actual images. I would also shoot an ISO 12233 chart with your own lens looking at things like consistency in the corner performance.

Again, congrats on the new lens.
