Don, I knew it would not be your thing and don't think most street photogs would need or want it. But for me, so used to a good viewfinder and not all that steady at handholding, it really helps me both see and keep the camera steady. It seriously undermines the sleek lines of the NEX, of course, but it is functional and I don't think it will harm the camera in any way. I like to use a Sigma 105 macro and it helps me to manual focus. Also, I can fold it out of the way and still flip the screen any way I want. So far I like it, but need to play with it more. Note: since it attaches to the tripod mount you cannot use the tripod with it, tho they do make a different mount for cameras that have a hotshoe centered above the LCD. Also, when it's attached, the camera does not sit flat because the screw sticks out on the bottom. It is not elegant but it's functional and the design will probably be tweaked eventually. I hope I am not hijacking this thread. If so maybe BB will move it where it should go!
I do it's a terrible shame Sony doesn't provide a good detachable electronic viewfinder on a camera with a sensor this good.
