I confess to being a bit of a w/angle junkie and find it odd that Schneider push the 90XL and 110XL as 4x5 lenses when they seem much better suited to 5x7 & 4x10 (possibly 8x10 with a bit of cutoff). At those formats you can get a lot more of that delicious 110/105 degree view into the frame. I recently picked up a 2nd hand 90 XL, and sent the front standard off for re-work simply because the 110XL was too close to the 150XL.

Damned if I'm getting rid of that 150XL!!!
