Have this lens for about 2 years.
Just 2 months ago, Autofocus no longer work,
Troubleshoot
switch AF ON/OFF a few times,fail to resolve.
switch main ON/OFF a few times,fail to resolve.
But it start autofocus again each time the focus ring being manually turn(light turn).
Just like kick-starting motor engine. Autofocus will fail again after few second times
Switch to use another len(50mmf1.4) on the same camera body. Autofocus is normal
My Suspect:
1) Maybe this zoom lens autofocus motor is not Ok?
2) Suspect viewfinder got fungus and affect AF only for specific lens?
(don't have another different lens to try)
3) Anything else that could affect this problem?
Like to hear more opinion.
It is a cheap lens but would like to use it.
Repair by Canon , worth while?
Thanks
