Unfortunately, the only 300mm 2.8 lens listed is the IS version

The procedure is not that complicated, but you need to pay attention to the connections on the circuit board. The mount is removed, and you need to remove the small screws that hold the connector board to the mount ring first.

I cannot do live chat due to I use a Mac, but I will monitor the thread if you have questions,

Canon EF 75-300mm f/4-5.6 III USM Lens Auto focus motor keep working back and forth but lense is not able to stop on focus right. Had eror 01 also sometime with manual focus.


If your AF motor is hunting then the lens probably needs to be looked at. I wouldn't recommend this as something to do at home so you will need to either find a repair shop if it is out of warranty or return it to Canon if it is in warranty.
