Using a 1.4 magnifier I am getting much more success than I did on film. Delighted. I got my 50mm f1, 21mm f2.8 and 24mm f2.8 done at the same time, assuming these to be the most sensitive to adjustment (of the lenses I own) and also, despite the M9 having manual lens setting, I find myself forgetting to do it sometimes. A 75mm lens shot with correction for a 21 is not easy to deal with.
