Thanks Cam. Typically the 110 or the 150 for stitching. I like the compression that these lenses give me. Its similar to the look I got when I was shooting film with a Horseman 617 and the Schneider 180mm lens.
Bernard can give his advice as well on stitching. He is very good at it, an expert. I stitch for the pano format, not for resolution. Resolution is a benefit of course.
