>>2891387>>2891398Good luck taking this shot with your "parallax corrected" viewfinders, dumbasses.
The crappy little projected frame corners moving around a few millimetres as you focus doesn't "correct" the fact that the optical axis of the viewfinder is usually displaced both vertically and horizontally from that of the lense; it's just a visual representation of how bad the problem is.
Never mind things like distortion, flare, or depth of field, which can also never be represented accurately by a separate viewfinder.
Refer to cameras like the Hologon or SWC or Ikon SW that try and minimise this problem by shifting the viewfinder to line up vertically with the lense.
