Autofocus Common Repair
This spring was made for the Canon XT but will fit other model Canon D SLR cameras
Sub-Mirror Springs are not available from Canon as an individual part. The complete Mirror box Unit must be purchased instead.
Note the comparison between the original and replacement parts. While we all have used a replacement spring from the film Rebel series, they require time consuming salvage and modifying especially the coil diameter.
