More camera control logic
From examples on my shelf...(quirks bolded)
K-3 digital SLR (no optional grip):
Shutter release: index or second finger
Shutter speed: index or second finger
Aperture: thumb
Focus: AF or left hand
Most of the film SLR and 35mm rangefinder cameras:
Shutter release: index or second finger or right hand
Shutter speed: index finger + thumb of right hand
Aperture: left hand
Focus: left hand
Exakta film SLRs:
Shutter release: index or thumb of left hand (depending on waist level or eye level shooting
Shutter speed: index finger + thumb either hand
Aperture: whatever hand is not supporting camera
Focus: whatever hand is not supporting camera
Yashica Lynx rangefinders:
Shutter release: index finger of right hand
Aperture, shutter speed, and focus...whatever is most comfortable (all controls on lens barrel)
Remainder of film SLRs and 35mm rangefinders:
Shutter release: index or second finger or right hand
Shutter speed: index finger of right hand
Aperture: left hand
Focus: left hand
Yashica 44 TLR:
Shutter release: index or second finger of right hand
Shutter speed: index finger + thumb either hand
Aperture: index finger either hand (lever and window hard to find)
Focus: left hand
Minolta Autocord TLR:
Shutter release: index or second finger of right hand
Shutter speed: index finger, usually right hand
Aperture: index finger, usually left hand (
Focus: combination of index + second fingers, both hands (lever across front of camera below taking lens)
Mamiya/Sekor 120 rangerfinder folder:
Shutter release: index finger of right hand
Shutter speed: thumb + forefinger, either hand
Aperture: index finger, usually right hand
Focus: right thumb
Strangely, all of the above are fairly intuitive in use, though the Autocord's use of EV settings* (viewed from the front) for shutter/aperture and conventional settings (viewed from the top) is a bit confusing at first, it becomes quite easy if one has a meter that reads out in EV.

* This is EV in the sense of Exposure Value, a unit-less number based on combination of shutter speed and relative aperture (f-number) serving as a measure of the amount of light reaching the film. (
