Does anyone know how these work? Specifically:
I understand that you can calibrate your zoom lens at four to eight different focal lengths so for example on a 70-200 one might choose 70, 100, 135, 200.
However what happens at ‘inbetween’ or intermediate focal lengths e.g 160mm?
Does the lens have a best guess I.e if 135mm was -5 and 200mm -8 then it might choose -6?
What if I set the lens to 136mm? Wil it choose the nearest calibration figure I.e -5 or will it revert to zero?
NB I also understand you can calibrate at differing focus distances too but let’s not over complicate for now... he says...
