Sony Alpha and manual lenses

[lauge]

I found this adapter for Nikon to Minolta/Sony, has anyone tried this? How much does an extra element effect the end result?

I use Sony Alpha bodies (A100, A700 and A350) with various mf lenses. It works fine, except that the A350 can only be used in manual mode (not A=aperture priority) unless you have a chipped adapter.
Apart from m42 and Adaptall-2 I also use some Pentacon lenses, sometimes with a tilt adapter.
