Does it cover 4x5 @ f/5.6 with some - yet, acceptable - vignetting? I shoot only BW.
Tnx!

Hi Emmanuel,
many thanks for the great links!
Cheers
Image circle and light fall off is mostly a non-issue on 4x5 at any aperture. Having used the 110mm SSXL on 4x5 to 8x10 (does NOT cover 8x10) since the late 90's when Schneider introduced this lens, it easily meets the image demands for 4x5. It has a snappy, contrastly personality image personality.

The 110 at wide open is not at its sharpest - particularly in the corners.
Fabulous at f/22.

And at f/22 it will cover 4x10, but needs a center filter to even things out.
The corners of a 4x5, you mean?
I must add that I have the both the 110mm XL and the 150mm XL. The reason I asked is that my 110mm XL is right now 800 miles away so I have no way to check in person whether it delivers objectionable vignetting or not @ f/5.6 on a 4x5. Both are very fine lenses, I used the 110mm on 8x10 color slides as well, without movements of course.
If you'd read the charts that Prof. (retired) Dr. Bigler, who I greet in passing, directed you to in post #2 above, you'd have seen that with the lens unshifted at f/5.6 at infinity the corners of 4x5 are around 1.1 stop down from the center. This is consistent with cos^4. In other words, with this lens mechanical vignetting is not a problem.
