Rated 3 out of 5 by TFD1 A700 issue
The eyepiece can block the sensors, under the viewfinder, that detect the user’s face and dim the LCD screen and trigger autofocus. I tried the eyepiece on both my A100 and my A700. (To be fair, the eyepiece is listed as compatible with the A700, but not the A100.) When I pushed the eyepiece down that last millimeter to get the faint click as it seats itself on the camera, the eyepiece blocked the sensors. On the A700, there was enough of the sensor exposed that I could trigger it by putting my finger there, but my face didn’t do it. On the A100, the eyepiece itself triggered the sensor.
But the good news is that sliding the eyepiece down against the final click, but not going through the click, allowed the sensors on both cameras to work fine. The view through the eyepiece was not affected at all. Nor was the look of the eyepiece on the camera, or the apparent security and stability of the eyepiece on the camera – that faint click really doesn’t do anything. I am generally very particular about having these things work right and not jury-rigging them, but I am satisfied enough here with the final result that I am keeping the eyepieces for both cameras.
I have read about this glitch on Alpha user websites - I am surprised that Sony would let a product go out with even this relatively minor flaw.

With my A300, i have the lcd screen protector, even without the lcd protector, the screen made it hard to get your eye to the viewfinder. This pushes it out to it's basically flush with the lcd screen. you can really get your eye up to the viewfinder well. it's amazing how much a few more MM's will really help with your pleasure of using the viewfinder
of course it increases your view too so focusing can be done better. you can tell a difference. I'm glad i purchased it especially just for pushing the view finder out a few extra mm's.

I ordered two if these (for my 300 and 350) and have been very please with the product. Not only does it extend the viewfinder pass the LCD, but having a larger view through the finder is pleasing. Only drawback -- can't use the eye activated autofocus, but it's OK -- I don't use the feature anyway (great feature though) --
