It was driving me crazy for a while. I could shift the fuzziness all around by focusing on certain area's. Decided to take my magnify glass and examine the neg first to find out what was actually sharp. Found out PROBABLY alot of camera wobble when extended out to 250-300mm. That and the enlarger being out of whack.
BTW: LOTS, LOTS, LOTS of enlarger lenses on Ebay. I have Nikkor but have heard that the Rodagon or Schnieders are better and they are both CHEAP on the net. Any thoughts?????
