Question about Canon Digital Cameras

1 Answer

Hi there i have a auto focus problem. i used mt 50D for the first time on saturday, after about 100 shots Err99 appeared, i turned the camera off and took the battery out an the error message never occured again, however since then the camera will not auto focus correctly with my 17-40 IS lens. the lens has worked perfectly on my 20D for the past couple of years. When going from close focus to distant focus (and distant to close) there is no autofocus whatsoever. the focus points highlight in red but the image is totally out of focus in all areas. i cannot shoot quickly and the camera cannot locate a focus point. Have you heard of this problem?

The camera is having problems with your lens and this is why it goues into the error mode. Try first cleaning the interface contacts on the lens ( see enclosed pic ) . If this does not sort the problem out then the auto focus motor ( or related hardware ) inside the lens will need attention. Also try other lenses to see whether it is only the lens ( I very seldom see this sort of problem cause by the body ; it is always the lens that gives this sort of trouble )hi there i have a - db49ae2.jpg

Blurry pictures


You did not say which lens or lenses you are using, but most auto-focus lenses have a switch for selecting manual or auto-focus. First, check your camera's menu settings to make sure auto-focus is enabled and then your lens to make sure you did not accidently leave it in the manual focus position? If it is in the auto-focus position and still not taking sharp pictures, switch it to manual and see if you can get it to focus correctly. It is also possible that your auto-focus alignment is out because your camera was bumped, jolted or dropped. If realignment is necessary, you can send the camera and lens to Nikon for repair or find a knowledgeable camera repairman.

Camera started with an err99 code, postupdating firmware, it is now showing err50,and sometimes also err 20. tried changin lenses, turning camera on/off, removing battery, and it will take one/two shots...


Receiving multiple error codes definitely indicates that your camera should be taken in for service. Unfortunately, there is nothing you can do on your end in terms of troubleshooting or fixing a range of error codes. The camera needs to be sent in for service.

My CASIO EXILIM camera wont forcus or keep the right exposure!


The focus frame does not appear on the monitor screen while following conditions.
• In the Auto mode, while the following settings are configured.
- Face Detection : ON
- Effect : Make-UP
- Auto Shutter : Detect Smile
• "MF" or "∞" selected for the focus setting.
• BEST SHOT scenes that use the above settings.
Example: "4 Portrait" BEST SHOT scene

* Changing the above settings will cause the focus frame to reappear.


If your camera wont keep the memory settigns after turn off the camera, its possible that you have some problem with the internal battery and need to be replaced.

Canon 50D. Hi, When I look through the viewfinder the top edge appears fuzzy. There is no problem with with the actual pics.


The focus screen might be loose.
Here's a video about focus screens. Maybe you can adjust it.
Happy Shooting!

Sometimes when taking photos the photos are fine and sometimes they are really blurry. Why is this haening?


this may not be the camera but the lighting situation of the photo. or how the camera is held this also happens on film cameras.
if the subject is not well lit or the flash fails to go off or is blocked by a finger then the shutter stays open longer to get enough light to see the image. if the auto focus apature is blocked it will not focus on the subject and will come out out of focus
if the camera moves in the time that the shot is taken it will blur.

if the blufing is from left to right or up and down it means the camer moved during the shot.
if the whole picture is blured all over this looks like being out of focus and not due to movement.

check your IOS speed setting for your camera if it is set low then the camera will needs a lot of light or show shutter speed to capture an image. set it to auto or higher than 100 is best for most situation

if the camera is set to manual an not automatic the camera will only shoot at the set shutter speed and this can cause bluring.


try some test shots on a table or a tripod and take several shots in automatic mode with auto focus on take them one after the other they should all be the same but if one is blurred then there is a problem with the metering of your camera if they are all fine they it is due to camera shake when the picture was taken.


a few tips.

hold the camera to the eye with the elbows against the side of the body.
in dark lit places try to use a tripod or some other support or external light source or flash.
ensure the fingers are away from the auto focus apature the lens and the flash light.

i hope this was helpful

After about 5 or 6 shots, it gives me an err99


"Canon has announced v1.03 firmware for the new EOS 50D digital, which they claim fixes a number of problems. The most notable of these is the 'Err99' issue that prevents the camera from taking pictures.

http://web.canon.jp/imaging/eosd/firm-e/eos50d/firmware.html

PLEASE NOTE: Please follow all instructions carefully when upgrading firmware and always use a mains power supply. If the update is not performed according to the instructions provided, the product may not be updated correctly, and may, in some cases, prevent the camera from operating."

Hope this helps. =)

More info for poor focus problem


I don't know about any misaligned focus feature on the D80. Have you checked to see what focusing mode you are using, ie. single auto focus, closest subject, or wide area focus. Closest subject can really throw off your focus. I would switch to single auto focus mode. Another reason for poor focus would be dust on the auto focus sensor which is located under the mirror box.

Check on the focus mode, if it's not a mechanical problem, I'd be willing to bet that's what it is.

I can't capture images


Digitak cameras have an auto focus in which you hold the button half way down and it will focus. a green light will appear at the top of the screen if the light is ideal for the shot. You can push the button all the way down without the half way for auto focus but you will have to hold it down for a few seconds for it to take the shot. It sounds as though you just may not be giving the camera enough time to actually take the shot.

I need advice on how to take Ice-hockey action pics...


Pictures get blurred because of several reasons:

Low shutter speed - occurs in low lightning conditions.
Auto focus not focused - occurs when pressing the shutter button all the way without waiting for the auto focus ready signal (green box)

To speed up the shutter do the following:
In Camera menu-Quality- Set ISO 100 for outdoor, ISO 400 indoor.

To avert focus problems, set camera menu-Rec- Focus-Infinity, Rec-Quick shutter-On

Hope that helps.
