I bought a Voigtlander 35 OVF for my RX1, and, I must say, it is easier to AF than I thought. While it would be nice to have an AF light near the eye, you can feel when the AF stops pretty easily, so it is pretty intuitive. I just went out and ripped off a bunch of test shots in various scenarios, and it doesn't seem like I'm much less accurate than with my X100s, although having the distance scale in the X100s' OVF is nice. The shots I missed are similar to the shots I'd likely miss with the X100s. It's great that the OVF is directly above the lens, so you only have to compensate for height a little bit when shooting something up close. While I'm obviously not going to want to use the OVF to shoot large aperture, up close, small subject type things, I think it'll be good for most general stuff, and, of course, zone focusing is also an option.
It's cool that you can deactivate the RX1's LCD, leaving only a strip at the bottom to show ISO/shutter/aperture. That's a nice option with the OVF attached.
I like using the LCD and OVF enough that I may actually return the EVF, which I never imagined would happen. I'm going to give it a little more time, though.
On a less important note, the Voigtlander OVF looks really cool on the camera, and the camera still fits in my tiniest Lowe Pro Apex 60 AW (I had cut a little divider out of the bag last year.)
p.s. I just realized that, when you deactivate the LCD, the distance scale still pops up for zone focusing. Nice.
