When was the first camera with dial(wheel) method to input settings introduced? Which model is it?
What is the method that is used before this?
The first camera to have essentially the same control types as on modern DSLRs (wheels for both aperture and shutter speed, etc.) was the Minolta Maxxum/Dynax 9000 professional 35mm autofocus SLR, released in 1985. The previously-introduced "prosumer" model, the Maxxum/Dynax 7000, as well as the follow-on entry-level Maxxum/Dynax 5000, used up/down buttons (which made it a real pain in the backside to use, even if focus happened automagically; I upgraded the moment the 9000 became available).
Prior to that, the standard layout would have been an aperture ring on the lens and a shutter speed dial on the camera body. (In the case of leaf shutters, the shutter speed control was/is usually a lever on the lens as well.)
I couldn't tell you specific models, but prior to electronically controlled aperture and shutter the aperture was a lever or ring on the lens itself (similar to how the focus ring operates on modern lenses) and the shutter speed was either a selector of some kind (lever, switch, etc) or was just bulb mode.
My Nikon F has a dial for shutter speeds. I bought it in 1970, but the F's design goes back to the very early 60s or late 50s.
Many enthusiast cameras of this era, in rangefinder, twin lens reflex and SLR styles, used dials.
