I'm looking at 40ish lenses for use on the RL3d for stitching large panos on a 60+ back. Resolution is reportedly highest with the smallest image circle. Any comparative thoughts on the 40mm HR W (90mm circle) vs. 43 XL Digitar (110mm circle) vs the 45mm Apo-sironar digital (125mm). I am particularly interested in the perceived sharpness in jumbo prints.
Thanks
