Focus Problem with Canon 60D

I run a high school yearbook and we own several Can 60D's. I noticed a couple of them would not autofocus is P mode with autofocus turned on on the lens. I tried a factory resent of the menus as recommended by a few people. I tried different lenses and cards. Nothing changed. Being a school we don't have ton of money so I'm wondering if anyone else has something I could try before sending them for repairs.

Try cleaning the contacts? You can YouTube how to do that properly. Hope this helps..

Do they AF in other modes?

Do they have "protective" filters on the lens?
Take them off and try. Also clean the contacts like suggested. Some lenses just plain do not play well with filters*, esp cheap/inexpensive ones. That filter is two more glass surfaces to get a coating of crud, dust, reflections etc to mess up AF and IQ. I use hoods to protect all my lenses, not filters.

*The Canon 100-400L mk 1 is an extreme example, it does not play well with any type of filter. I have read of people who sold their lens because "I got a lemon. Won't focus." Then when they saw images made without a filter they were astonished at the difference.

Is there a nearby camera store where you could take them and see if they can tell you what’s wrong? We

Try to set the focus on center point -then check it on manual and see if it is better. Maybe go to menu and do a camera reset the kids may need to reset the cameras after another student messes with the menu-center point focus is the default setting for sharpness-that and getting them to see the point of focus on the screen itself. They are just beginners -baby steps.They need to learn the ap.shutter speed ,and Iso, concepts first-I make them shoot Manual to learn this. Good luck it's a steep learning curve of at least 3 lessons! But it pays off for those wanting full expression. I try not to flood them with too much at once, but the students who are serious will appreciate it.

In addition to reset camera settings also clear all custom functions. Someone may have set back button focus, which removes focus from the shutter button.

Have you tried adjusting the Dioptric adjustment knob?

The diopter shouldn't have any effect on autofocus or am I mistaken?

A good quality filter will protect your expensive lens better than any hood can.
A good quality filter will not stand in the way of auto focus.
AF problems have never happened to me in many years, even with the cumbersome polarizing filter.
****Just my opinion and experience****

You can adjust the focus of both the lens and the camera on the 60D. This YouTube tells you how.
