Alphatron have released the full specs for their EVF made by TVLogic. It looks to be a great little unit, as long as there is is no display lag and you can get accurate focus, I think it might be a great addition to my kit.
Also of interest at Alphatron is what looks to be a native F3 mount 16-28mm F2.8 variable prime from Zunow. This would be a useful lens on Steadicam.
