The adaptor does not do infinity focus due to the lens inside of it...you can get really close..however, when you start working with the picture is is soft like my first picture above....it is sharp you still have some of the soft edges....I would say 50% of my shots are not at infinity focus.....so really does not matter to me...If you look for one without the lens...it like using an extension tube...so you start getting into the macro arena.....if you like the A700...I would see if you can pick one up cheaply...and the Minolta AF lenses are a steal right now...I picked up two from a local camera store for $50.00 each...because they do not know what to do with them....it is actually a fun camera....still have the learning curve with mine right now...now the Sigma SD14 that I have converted to Nikon F mount give me infinity focus...and the Foven Sensor produces some very nice color and the whole thing can be picked up for less than $600.00 with the conversion adapter...
This is a picture I just took with the adapter on a Sony A700 using Nikkor-H 50mm F1.2 Manual focus lens...f-stop at 11 with built in flash....contrast and minimal manipulation, cropped at 65% to 75%...at infinity focus
