Thread: Lens Calibration

  1. #1

    Default Lens Calibration

    Does it mean that if the lens that you bought is not very sharp, you can send it to the service center to have it calibrated for better sharpness? Or the sharpness of the lens is determined at the outset?

    recalibration would help if the lack of sharpness is due to misalignment... don't think it would help if its due to the design of the lens...

    Does lens calibration involves (1) correcting the lens for front/back focusing error so that it can focus accurately or does it involves (2) correcting the lens when it is "not as sharp as it should be" even when focus is accurate (w/o front back focusing problem)?

    For (1), it means calibration is to correct a lens problem that is related to the camera right?
    For (2), it means calibration is to correct a lens problem that is not related to camera right?

    I think mainly (1)... with (2), provided all the lens elements are seated correctly and the lens doesn't have any flaws beyond acceptable tolerances, I don't think there's anything that can be done... probably a design thing...
