Canon AF Issues

Hi,

I am using a 30D with a 17-85 lense, recently when I attempt to take a long range shot the camera/lense will not lock in and focus. The lense will move back in forth and unable to lock on a focal point. I have tested and it is only happening on long shots, if I zoom in on say an item 25-50 feet away it is fine but when I go outside that range it cannot get focused.

Thanks in advance for your assitance.

Kevin

    I'm having the same problem. And the 30D back focuses in AF. Fully frustrating!

    My Canon EOS 30D has the same issue - often 'searches' for correct focus, especially in low-light/high ISO situations. About 50% of my photos are out of focus just enough to be really frustrating when shot in AF mode.

    No matter what lens I attach, my canon 30D auto focus is unreliable. We sent it to be "cleaned", and it worked for a few weeks without a problem, but now it is back to the same old tricks. It's extremely annoying, particularly when you need to focus on something quickly or in low light.
    Any other suggestions?

Change from auto focus to manual focus or focus using only one focal square and change the setting to One Shot. You may need to shoot in Manual (M) mode though. Any of the "auto" modes will not let you.

I have a canon 40D and it will not shoot in auto focus .. was working fine today and just stopped. will not do anything set on AF but in manuel it will ,,, Help !


A couple of possible reasons:
You are trying to take the shot with the lens too close to the subject. If you attempt to take a shot with AF on while too close then the camera won't take the photo. Try backing up from the subject a bit.
Which camera mode are you in? If you are using the green box (automatic) mode then in very low-light settings the camera may refuse to take the photo.
The AF on your lens might be broken. Try using a different lens (if you have one available). Do other lenses have the same problem?

30D locks up and won't take pictures.


are you taking photos of still or moving subjects? One shot is suitable for still subjects, someone sitting down or still life shots. The camera will balk at you if you are constantly panning or have moving items in the fiewfinder field of the focus points and it is set in one-shot mode.
try changing to AI Servo and see if the problem continues.

500mm lens will not function with my Canon digital Rebel XT.


This lens will work with Canon cameras. I use one on my Canon 30D. It is a fixed F8 you can not use auto or green box because there are not any contacts on the lens to talk to the camera. Its back to the basics manual adjust shutter and ISO to the get a correct exposer. DEFINITLY NOT A POINT AND SHOOT LENS.
