SOURCE: My 300D wont lock on a point in its AF setting

If you are unable to focus in broad daylight and it just hunts through the whole focus range without locking, then it sounds like a problem with sub-mirror pin (also called the second mirror pin). My 300D just had this problem and I had to send to service to get fixed. I sent to http://www.keh.com/ as they were at least $50 cheaper than going straight to Canon. Just got it backed and it works like a charm again.

SOURCE: Problem with Canon EOS D60 Digital Camera

You need to clean the gold contacts with a soft pencil eraser. Remove the lens, and clean the contacts on it. Then hold the camera so the lens opening is pointing down and clean the contacts on the camera. Ensure no debris gets into the camera body and none is left behind on the lens.
Put it all back together and you should be good to go.

SOURCE: Canon AF Issues

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.

SOURCE: Cleaned inside of viewfinder, now AF focus lights gone

Then you learn, when everything works fine, dont mess with it! Have a look at the gold pins that rely the body to the lens. Also check that your lens manual switch focus is engaged... Try a friend lens to see if its your cam or the lens...

SOURCE: Auto focus suddenly stopped working

This may not be the same as your issue, but our AF stopped working as well. I tried all the recommended fixes - removing the card and battery, recharging the latter, removing the lens and cleaning the contacts, etc. None of those things worked. However, I then switched to MF, requiring me to turn the barrel, and I realized it was stuck and just needed a little force to get unstuck. Might have been the humidity. Anyway, our problem was solved - AF was back to normal after that.

Most entry level SLR cameras will struggle to focus in low light, especially with the kit lens. By rights the flash should popup and emit a flash pulse to help focus. This is called focus assist. You might have to consult the manual to check if this function is turned on or not.

Hi there. i owned a Canon EOS 60D model camera. The problem is, its AF option is not working except Auto n 'C' modes. While i am trying to use it in M mode with AF, its not working but in auto mode an


Are you sure you did not put the AF/ MF switch in the wrong position? Although I don't think it would focus in Auto mode. In all other modes, are you sure you selected a (or more) focus point(s) in the centre of the frame?
When the selected focus point is on the side of the frame it won't focus on the parts you want it to focus. Then while pointing to the point you want the camera to focus, please press the shutter release button half and what till it focusses. Then press it the whole way down. Be aware the camera needs enough light to focus and certainly can't focus with a lens wit a min aperture of 6 or a larger number. On your 18-135 you can shoot at f16 because it will first focus on wide open and only close the aperture after you pressed the button.

Auto focus not working


Have you checked the lens AF/MF button?
Perhaps your lens is in Manual Focus mode?

Hi Ref: Digital Camera - Pentax K200 model It keeps auto focusing when in manual mode. Regards Chris


Putting the camera in manual mode still doesn't change the focus routine. If you want manual focus, there is a switch near the lens on the left allowing AF (auto focus) and MF(manual focus).

Why are all of my photos blurry? I have a Canon Rebel T2i


You have the focus set to manual. Either turn the focus ring yourself, or find the little switch on the lens that turns it on (MF = manual focus, AF = auto focus).

Hi I bought my canon 1000d on september 2009 and a year later the autofocus doesnt want to work. In the viewfinder on the far right a number 9 has a green dot flashing next to it. Please help!! Ruthven...


The 9 you see is the maximum "burst" which is (pictures made in rapid succession) and is not an issue with your problem at this time the flashing green dot is the in focus confirmation light and it's good that you are seeing this as we will use it to remedy the problem.

Manual focus switch
Diagram here

What I want you to do is put the AF-MF switch in the manual mode if it's already in manual mode then that was your problem switch to AF and go take some pictures. If it's in AF mode switch to MF make sure teh camera is on and look through the viewfinder at a subject say 15 feet (4.5 meters) away something that has contrast then turn the manual focus ring on the camera slowly until it appears to your ey that it's coming into focus when it's in focus the green light will come on solid, now you know what you are looking for focus an several different objects at different distances and focus manually. Now switch the lens over to AF (auto focus) and focus on the same thing but let the camera do the focusing What auto focus will not focus on in something with little or no contrast like water clear blue sky a painted wall mirror chrome glass and a few other things.
Here is another diagram to check make sure you are in the correct mode.

Now for the focus point in the viewfinder make sure it's in the center position.

To adjust the focus point do this

Once you have the camera set to the center focus point and the correct AF mode (one shot) auto focus should return to your camera. Have fun Robert from London Ontario Canada

My canon rebel XSi will not auto focus


Actually what I found to solve the problem was to first set the lens in "MF" and practice taking a picture manually to see if that would work. When I did this, I discovered that the fine tuning portion of the lens was somehow stuck mechanically. I heard a loud click as I turned it. That was all it took to fix the focusing mechanism on the lens. Then I set to "AF" and Voila, the camera worked just fine.

Nikkon d50 wont auto focus


the D50 will only auto focus with an AF-S lens...make sure you are using an AF-S lens.

Also, check the swithc on the lens is set to "A" not "M" ...

Also, in the menu, check you set the camera as autofocus, not manual focus

Focus modes


There are four focus modes: S-AF (Single auto focus), C-AF (Continuous auto focus), MF (Manual Focus), and S-AF/MF (Simultaneous mode). (SINGLE Auto Focus): Focusing is performed once when the shutter button is pressed halfway. C-AF (CONTINUOUS Auto Focus): The camera repeats focusing while the shutter button is pressed halfway. (MANUAL FOCUS): The function allows you to manually focus on any subject while looking through the viewfinder. SIMULTANEOUS USE of S-AF mode and MF mode: You can fine-adjust focus manually by turning the focus ring after AF is performed in the S-AF mode.
