Question about Canon 35mm f/1.4L EF USM Autofocus Lens
I am us using a Canon 20D EOS body with a 3yr old Canon 17 40mm EF lens that has all of the sudden quit working with the autofocus feature. Other Canon lenses work with the body so I have narrowed it to only this lens. Light meter does work under Af mode. I have made sure that the digital sensors are free of any "gunk" and have been careful when changing lenses and recapping as well. If I am looking at replacing a sensor, will it require replacing the entire sensor pad and is it worth the possible repair costs?
Since the problem is limited to this lens, I highly doubt that you would have to replace the cameras AF sensors.
Since you only have the problem with this lens, I am afraid that you will have to get the lens repaired. Is the lens also 3 years old? Did you get it with MACK extended warranty?
Sometimes, Canon do these kinds of repairs for free, if they discover that there was some manufacturing error that caused it to fail. So be sure that you get it to a certified canon workshop.
I hope this helps,
