What are the facts around this claim? I take a Hasselblad with a 110/2, and a magnifying hood...critically focus on something ~3' away, and I don't see a focus change with a UV filter on or off...and all my Noctilux and Summilux images are dead on focus wide open...and I do use UV filters, and I do a LOT of close up work...I would think I'd see it there. Perhaps there is some focus shift, but it is certainly not significant.
