Customer Question
I have a Canon...

I have a Canon EF 70-200 1:4. the automatic focus has gone out. How do I get it fixed. What ballpark $ figure?

Technician's Assistant: What Canon model do you have?

Where would I find the model #?

Technician's Assistant: The Camera Technician will be able to walk you through that. What have you tried so far with your Canon?

Not sure what you mean. The automatic focus just stopped working.

Technician's Assistant: Anything else you want the Camera Expert to know before I connect you?

No, I'm just trying to get advice on fixing it.

- Try removing the lens, then try cleaning the terminals on the lens mount, by wiping very gently with a clean, dry soft cloth - gently so as to not abrade the delicate coating on the terminals.

A few questions about the lens:

How old is the lens? in months or years since you bought it.

Has the lens been dropped or otherwise subjected to mechanical shock(s) in its lifetime?
Has the lens been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?
Has it ever been subjected to a humidity higher than 85 % or gotten wet ?
Has the camera this lens was used with, been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?

(If all else fails, you may start a repair-servicing process for this Canon EF lens, by going to

https://www.usa.canon.com/internet/portal/us/home/support/service-repair

and using it to start servicing on your lens.)

If this answers your question, please rate my answer. A five-star rating would be appreciated!
