I wonder if Mr. Reichmann is still using the NEX-7 or if he has started using another camera more and also what he might think of this firmware upgrade. I know he liked the Olympus OM-D as an alternative. I purchased the OM-D but the user interface was too infuriating for me. The 7's, on the other hand, strangely seems quite intuitive to me and I am very happy with it. As prices start to fall a bit I can't wait to pick up another second-hand body and have it converted for IR ... plus the introduction of the new 35mm lens, I will be happy as a pig in mud!
I, too, find the NEX-7 to be quite intuitive to use (I tried the Panasonic GH-2 awhile back, and found it quite bad in that regard).
You might like to hear that I got a second NEX-7 converted to IR by lifepixel, and it works really great. It focusses far more accurately in IR than my previous IR camera (a Nikon DSLR) - as good as the regular unconverted NEX-7 (because of how the focussing is implemented in the NEX, the usual difference in focussing between visual wavelengths and IR isn't an issue here). I use it with the Sony 18-55 & 18-200 lenses, and haven't had any issues with hot spots, or any other problems whatsoever.
