<p>Ray--the F2 is a joy to use. And there ARE excellent "K" screens available for reasonable prices. A screen with an obvious defect certainly detracts from the view through the finder. I understand that the F3 screens will fit (I could be way off here)--and there are lots of F3 red dot K screens on the lists. My F2s all have the "A" screen which is good, too. Keep looking!<br>
