It seems it's all Oskar Barnack's fault. He put shutter dial on the body, not on the lens, as god intended. This is how cameras should be operated, isn't it? Aperture and shutter should be together, which enables constant Ev by simply turning both dials. And, lens absolutely should have DOF scale for different f-stops. I mean, at least the later is the foundation of photography, isn't it? Well, they managed to push these down our throats. Why on earth did we accept that? My guess is, it was pre-digital equivalent of "megapixel madness". Fill it with features, sell it to the masses. Ok, I accept the "P" mode. It's fair. Use evaluative metering to get a decent exposure for shots where the moment is everything. But what on earth is the purpose of Tv and Av? If i want to control my exposure, I HAVE to take different readings and set exposure compensation anyway, so it's actually the same as simply shooting in manual mode at the first place. And even dials wouldn't be all that bad, if manual mode would let me keep my exposure value constant, and simply choose any of the equivalent settings (probably some bodies do, my current don't). But the true sin (which is the consequence of using dials in the first place) is taking away DOF scale. They basically sacrificed the basic tool every photographer needs to implement features which made photography more accessible to everyman, ruining the camera in the process. How on earth did real photographers accept that?
