hi charlie: yes, once you're a couple of stops down from the fastest speed in a leaf shutter the variability becomes insignificant. generally you can test the speeds conventionally at the slower speeds up to 1/125 or so and if those are okay generally the top 2 will be too. i think the factory generallyset the fastest speed assuming the lens would be pretty much wide open.... not always a good assumption, but as henry suggests, they generally hit close enough for the film's latitude. not sure i understand your question about f stops accumulating errors over time. rick : ) = |
