exposure - Do any other manufacturers other than Canon use the terms Av and Tv?


Canon uses "Av" (aperture variable) for the automatic exposure mode that entails the user choosing the aperture and the camera body choosing the shutter speed. This mode is called "A" by Nikon, and I think other manufacturers (Panasonic comes to mind, see this review of the GF1).


The mode generally called "S" (shutter priority) is called "Tv" (time variable) by Canon.


Do any other manufacturers use the same designations as Canon?



Answer



A quick review of photos of control dials shows the following:


Tv, Av, P, M
Pentax, Canon


S, A, P, M
Nikon, Sony, Olympus, Panasonic, Ricoh, Samsung, Fuji, Sigma



Leica has its own nomenclature.
I had always thought of Tv and Av meaning Time variable and Aperture variable.
