If you're looking for a WA Dagor, the lens to look for is the 4 3/8". Not quite as wide as the 90 (actual is around 110mm), it will cover 5x7 with movement, even fairly wide open. Although not multicoated, it is very flare-free and is capable of producing accurately exposed chromes. Mine is in a Rapax shutter, so you wouldn't be able to use it with strobes, and like the 3 5/8", it would require a custom filter adapter. Since I mostly shoot b/w with it, I have not had much need of filters so this has not been a problem. YMMV.
