The potential misting, fogging and dusting of the SLT mirror is one of the reasons why I personally don’t think that design belongs in a 7 series camera; maybe the mirror should be made like a film with a roll of it at one end and periodically it rolls on to a new section; when it’s used up you just replace it like a ‘film’ canister.
The whole reason why we had to have the SLT design is because of video, there has been a constant baying for video to be inserted into the SLR design for a long time and those have got what they wanted….but where is OUR camera, and I don’t mean a token gesture DSLR cobbled together from left over system parts from the current SLT, I mean an updated A700 with the latest sensor.
Anyway back to the SLT module for the NEX, I think the idea would probably sell (mainly because people like gadgets, I like gadgets myself if they make sense) if it worked well and didn’t cost the moon; the problem is EVF’s use power so if you had the A-mount focus motor and aperture solenoid/motor in the adapter as well using power maybe they should make a dual battery power grip for the NEX as well…chuckle.

Ps. The only other drawback I can think of is when you want to store the add-on SLT adapter + EVF module in a bag or pouch how is one supposed to keep dust out of it…always?
