Neal, Jeff, I'll look for a 135. They seem to be more $ than 150mm. Hmm. Just curios though if for some strange reason I wanted to do a 20 x 24 enlargement, would a 150 be more appropriate at that size?

Neal, the car analogy unfortunately works for me. I spent a lot on cars before photography. Now I spend a lot on photo gear.
But curious (I know this will get me in trouble) about your adventures with the D5500 color head on a D2. Any descriptison/pics or memory of the process?

George, I'll take a look

Thanks all for the help

Dan
