Canon 75-300mm Won't Autofocus

\015 When i flip the switch for autofocus the camera still says its in MF modein aperture mode all i see is fOO and i cant change this either.\015

Answers :

Just to clarify, this is a Canon 75-300mm lens, and not another make?

\015\012f00 is the same thing you get when no lens is attached to the camera - take it off, switch on and you'll see the same error.
\015\012
\015\012It sounds like either the lens or the camera is faulty - do you have another lens and/or camera to test? If you have another lens and it works, I'd say the 75-300 is faulty. If the other lens is also faulty, I'd say the camera is bad so try to test the lenses on another (you could take it into a camera shop and they could try it on one of their cameras).
\015\012
\015\012One possible thing to check is that all the contacts are clean on the lens and camera, no dust or dirt anywhere.
\015\012
\015\012Take the camera back to basics, put it in fully auto mode, with just the lens on and see if it acts any differently.

Autofocus has failed on the CAnon EOS 40D. I can power the camera up with lens in manual but as soon as I go to autofocus it becomes unresponsive. The viewfinder goes black. Swapped batteries and lenses. I've had this body for five days. It is a canon refurb. I will also be contacting the dealer.


It's not the Autofocus, there's no 'non-engineer' fix. Lens and slider have failed, it's basically broken inside and I suspect it was the original fault. It's about £160-200 outside of warranty to fix via a canon authorised repair agent such as ... Canon EOS 40D Digital Camera

My Canon digital rebel will not autofocus correctly. My camera has 7 points autofocus, but it will only autofocus on the far right point. All other points are not used. I have had the camera for 14 months and the problem just began. If I want to focus on anything in the left to center of the field of vision, I cannot do it. However, the lens focuses manually very well. Why won't my camera focus on other points than the far right one?
