Our Custom Autofocus calibration mates your EOS 40D with your Canon EF lens, ensuring the most accurate focusing possible. Cameras and lenses are both mass-produced to fall within certain tolerance ranges, but if you end up with units that are on opposite ends of those ranges, the result can be disappointing performance.
LeZot's custom calibration adjusts AF operation for your specific lens. If you use many lenses, but have problems with only one, this service will NOT disturb the operation of your other lenses.
Adjustment with after-market lenses (non-Canon brand) may also be possible, but may affect focusing operation with other lenses.
THIS SERVICE IS CUSTOM ADJUSTMENT AT $50.00 PER LENS, MULTIPLE LENSES CAN BE ADJUSTED TO MATCH YOUR CAMERA BODY.
