Question about Canon Rebel XT / EOS 350D Digital Camera

5 Answers

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?

    My Canon EOS Rebel XT will not autofocus, when I turn the switch to manual focus it still will not focus clearly. I deleted all the settings in case i accidentally changed something, but i can't get it to focus clearly at all.

    I have had my Canon Rebel for over a year now and have had my 75-300 mm lense for some times as well, and have always used the auto focus, and now all of a sudden it doesn't work. All it wants to do is focus in and out, but never to a clear focus, and will not allow me to snap a picture.

    My Canon Digital Rebel won't autofocus any longer. None of the focus location red dots light up either. I've tried two different lenses (making sure they are in autofocus, not manual focus mode) and I get the same thing. First it adjusts focus all the way in one direction, then all the way in the other direction, then I get a green dot inside the lens and it won't take a picture. If I switch to manual focus I can focus fine and take pictures fine.

    I've a very similar issue.

    I was taking pictures when suddenly it no longer would do so. I finally switched to manual focus and it would again take pictures. Back on auto focus the lens (have tried 3) would focus in and out and then the focus conformation light would start blinking and no picture is possible. I've already tried setting the foucus points and it all was well with them. (I was using automatic settings in any case not manual.)

    I've downloaded the manual with no luch and searched the web. I'm open to suggestions to get this working again as I was just made the staff photographer for the youth sports league here in town and fighting with manual focus will make getting the best shots far more difficult.

I had this problem awhile ago - you must have accidently adjusted the focal area - it is sooooo easy to do without realising it. Here is what I was told:

Most likely, you have changed the AF point, which only takes effect in the creative modes (Manual, Av, Tv, P, etc)

There should be a button on your camera that has a grid like pattern above it, like
- - - - -

or so. press that, look through the viewfinder, and move the shutter or rear wheel, you should see the different AF points like up in red, and as you turn different ones will light up, and eventually all of them. also, you can look on the screen on top (or back, if its a rebel) and it will show you which ones are selected while in that mode, instead of looking through the viewfinder.

    This totally worked. I have been searching all over, and I was so upset that my 1 year old Rebel was not autofocusing. Thanks so much, Cyberkitty!

It is possible that your focus sensors are dirty. remove the lens to the body and try to clean the mirror, open the mirror and clean the small glass ( around 7 pcs). Clean all the mirrors inside. Also check if there is dent or misaligned mirror.
As an amateur photographer, I always set my focus sensor in the mid section only.

Why does my canon eos rebel t3 not take a picture when the shutter button is depressed but tje red eye reduction button keeps flashing and the video still works?

Usually, it means that the timer function has been turned on, and the camera is going through a countdown to trigger the shutter.

After that, it means that something else is not working correctly. If video works and records, then you know that the sensor and memory are functioning correctly. At that point, check to see whether your camera and lens are set for the form of autofocus or manual focus you want and that the aperture is still functioning correctly.

At some point, switch the camera to an all manual settings mode and try the shutter switch. If it still does not take a picture, the switch may have a problem.

There is a seperate sensor for the autofocus. IT is either bad or dirty. You may not be able to clean it either.

Will a quantaray 28-105 1:3.8-5.4 Zoom lens Autofocus from a 35mm rebel ti fit on Canon EOS Digital Rebel 6.3 MP 300D?

The 35mm Rebel Ti and the Rebel 300D use the same lens mounting protocol. All Canon cameras designated 'EOS' use the autofocus EF lenses. If your Quantaray lens worked on the Rebel Ti, it will fit and should work on the Rebel 300D.

Canon 400d constant backfocus

Backfocus problems will be magnified when using wide aperture lens with shallow depth of field, nice lens btw. Camera's adjustments for manual and autofocus are inside mirror cage behind mirror, and you dont want to risk getting dust on sensor or damaging sensor. Qualified camera repair shop or sending to canon for adjustment would be my suggestion.

Autofocus jumps around and often will not settle on the correct setting

what i do is usually put it onto manual focus then back to auto focus, what it may be is that you are using the wrong lens for your subject :/

Canon 400D. Autofocus problem

(facing the LCD screen towards you, as if you're going to take a photo) there's a button in the upper right-hand corner that will allow
you to AF to a certain point (9-pts total) or the center, or all 9-points, maybe you have it set to one point and it's off center??
definitely sounds like a camera setting probelm
just a thought

Only one auto focus point

have you already pushed the focus point button - top right, under your thumb and then push the set button? Pushing the set button will flip between only the centre focus point and all 7.
