In other words: it aint that simple....
Ahh--no wonder I love the magnifier with the M8. My optometrist said I need the very smallest bit of + diopter for my eyes

When the M8's RF is aligned, I find the RF mechanism superior to any AF I've used to date, including moving subjects. When I'm really tired, though, the AF comes out (except in low light--the M8 is still better).

On the DMR, it's been a real struggle for me to get good focus without stopping down a lot.

The Brightscreen screen and magnifier were, in a word, terrible. The basic DMR screen not any better; I bought a new screen from Leica on Rob S.'s recommendation and it's much better, though I wish there was a magnifier as good as the DMR as for the M8.

I'm currently getting all my R lenses checked (right now the best is the 100 APO macro), and since I have a ton of shooting to do in the next months, I'm hoping I get this solved, since I'm ever more in love with the DMR files (and love using the M8 and DMR together, because they look so similar when processed
