How to Calibrate Your Lens

Have you ever noticed your lens isn’t always pin-sharp when using autofocus?

This lens autofocus problem can happen because lenses can drift over time. You want your autofocus to be pin-sharp – I demonstrate how to simply calibrate your lens autofocus without needing to buy a lens calibration tool or calibration chart. You’ll need the following:

➡️ A piece of whiteboard
➡️ A standard ruler
➡️ A pen or pencil
➡️ The lens for calibrating
➡️ Your camera with tripod

In this demo, I calibrate autofocus on my Canon 85mm f1.2 lens, however, the process is similar for most camera brands and lenses.

  1. Hi Karl,
    thanks for this instructive video. It may be a silly question, but does this also work with zoom lenses?

    thx
    Marco
