Any opinions on using a Fujinon W 135mm on a 4x5 Crown Graphic? Thanks.

Fujinons have a good reputation and the 135/5.6 has more coverage than you can use on a Crown. It will probably give better image quality in the corners (with no movements) than a 135/4.7 Optar but the one comparison test I've seen tested two Fujis. One shot much better than the Optar, the other shot worse. See http://www.hevanet.com/cperez/index1.html .

If you can get the lens with the right of return, get it and test quickly.
