Williams, Lens Clarity, page 191 > While I generally agree with this quote, especially with mirror flapping cameras, an M camera is a different "ballgame." As a long time competition shooter (rifle) I am well versed in the art of taking a breath, letting half of it out, then squeezing it off in between heart beats. This works just as well with a camera, as Byron Rakitzis pointed out. I have a 20x24 Cibachrome on my wall, right here in front of me, taken with my M6, hand held. No one can believe it was taken with a 35mm camera much less hand held. It is "dead" sharp. Not a hint of anything to degrade the resolution. M6, 35/1.4 ASPH, 1/125 @ f/5.6, Fuji MS 100/1000 @ 200.
