David, I think you will find the same feeling like me that the old MD lenses even if they are not perfect on the cheap Full frame simulator, they are still fun to use with the size and good construction they where.
So far I found the perfect setting for the NEX 7 with those old lenses. You put your camera in Speed priority. Because the lenses if not connected to the camera, you can Create what is not available in Manual mode on the NEX and even on the A99. You have now a single setup that can switch from Video and Photo with perfect control and also with the ability to put priority on the aperture also and let the camera adjust alone the ISO, and you can quickly correct the EV with the other wheel.
I found annoying with Sony that in video mode, even if you are in 24p, the camera always want to shutter at 1/50s minimum, this keep you a good one stop of light that make the difference in a Noisy or not movie.
Instead you want to make a poster of your picture, I still recommend the adapter at F1.2 in movie and also for "web" and 4x6 printing album

. I like to take picture when I almost don't have to move the slider in Lightroom to get my effect, I have also put a custom hood on the lens that capture some more flare and eat some more light in the corner to create vignetting.
