Analog film photography and cameras

the trouble i had with medium format is unless you use a tripod and mirror-up with cable release you always seem to get movement from mirror slap, unless you use flash.
you don't notice it until you go to print big, which for work that's going to repro is important so i always shot jobs on a tripod which i preferred anyway but as a walk around camera they are a bit limiting IMHO, although with 400 film i would hand hold and use the mirror-up.
i use 35mm didital in the same way, tripod/mirror up as movement seems to be exacerbated with digital as the sensor is just a micron thick whereas film has several layers for light to bounce around in so you don't notice small amounts of movement.
hand holding at low speeds (1/60-1/125) always seems to show micro-movement at 100% it looks sharp 'enough' but compared to using a tripod it's often soft.

But for reportage you can get away with 1/125 on 400 film - interiors/weddings/portrait/landscape/buildings tripods are the way to go
