EOS Rebel T3 not focusing or taking pictures

[moma]

I have had my camera for 2 years and have had no problems.  Now it won't focus properly when using the LCD screen.  It also says it is busy when I try to take a picture. Help!! It will take pictures when I use the viewfinder.

Do you have mirror lockup accidentally selected? If so, it will take two presses of the shutter release button to take a picture, and the viewfinder will black out until the second press of the shutter button.

Weirdest thing my Canon 1000 Rebel stopped taking pictures although everything else like fous and shutter were working OK. i took off the lens to have a look to see if the shutter was working, pushed the shutter button and the shutter mirror worked fine. Then I noticed it had taken a white picture. Put the lens back on and now its taking pictures again. Maybe it just reset itself.

Some cameras won't take a picture if the lens reports that it can't focus. That's the likely answer in your case, probably because there's not enough light. The screen uses a different focusing system, so it may not have the same problem.

Some flashes can provide a focus assist beam. Maybe that would help.

Hi Quaiser,

As Bob points out... if the camera wont take a photo in AF mode but will take a photo in manual mode... it usually means the camera does not think it was able to achieve focus.  

The camera will struggle to focus in poor lighting conditions.  It may also struggle to focus if there is not very much "contrast" (e.g. if you point a camera straight up at a plain blue sky the camera wont be able to achieve focus -- this has to do with how the focus system works.)

If you have fantastic lighting AND the subject has lots of contrasty details and it *still* can't focus... then that would be an indication of a problem.

In poor lighting with low contrast... you can use the "AF Assist" beam option with several Canon speedlite flashes and it will will probably be able to achieve focus anyway.

Not sure where you are coming from, but if you leave the camera in Green Square, you can just point and shoot.

If put it in green square, hold it to your eye and look through the viewfinder, it is pretty obvious where the shutter button is.

A DSLR *is* a complicated beast. The whole point is to give you enough options to get images when the auto modes fail, and to allow you to realize your vision - which might not be what the makers of the camera bake into the auto modes.
