    WHY sigma 120-600 5-6.3 ???

    • Adynaton

      From the time Sigma was hesitating between a 120-600 and a 150-600, or the early thoughts about a Global Vision telephoto zoom lens. Nothing for the future here.

        oh, makes sense

    It took some time before I understood what that Canon camera is about… It’s a DSLR with a short, mirrorless-like flange-back distance! Everything has to move around inside it when the shutter button is pressed – mirror, focusing screen, and sensor…

    While I look through the SLR viewfinder, the focusing screen sits in the focal plane with the mirror behind it, directing the light upwards through the viewfinder prism.

    When I press the shutter button, the mirror flips out of the way to the back of the mirror box, the focusing screen flips upwards to the top of the mirror box, and the sensor flips up from the bottom to where the focusing screen was.

    After the shot, the sensor flips down again, the mirror comes back and so does the focusing screen…

    Brilliant. But I guess assuring the accurate positioning of the focusing screen and the sensor won’t be cheap.
