I used the Visio flex 2 on the M11.  It was great, with the EV1 being much better experience...focus helpers are the magnification and focus peaking.  Collectively they work great together.  I do think the EV1 gives a clearer picture and better focus experience.

Thats good to read. I was hesitant at first as I am with anything new that deviated from traditional concepts. I Have the Visoflex for my M11's and only use that whn I have a close focus lens that needs it. But I wonder how they would compare. I think the EV1 has a nicer viewfinder. 

By any chance, does it give a focus confirmation indicator of any kind or does it just let you see the area you are focusing on more clearly?

Thanks!

It's pretty amazing.  Very easy to focus and definitely seems accurate.  For me, with my eyesight, it is definitely faster than my M11.
