Having problems with your Canon EOS 40D Body Only Digital Camera ?

Shutter will fire intermitantly on Canon 40D. It focuses but will not fire but if pressed repeatedly it will fire after several shutter presses. I have changed batteries, I have swapped to other lenses (including a Canon lens) but still have the problem. Any suggestions or does this go back to Canon ? : (

Answers :

A Canon camera mechanic told me that on the 40D this is caused by the rubber part under the shutter button not springing back quickly enough, at least that was how he described it. It's a simple matter for a camera tech to fit a new one. I go to Whiltons Camera Service in Elizabeth St. Sydney. I've been going there for about 25 years and they are the best I know of.
This is just a possibility not really a solution: If the AF spot is aimed at a part of the picture lacking details, it cannot focus (all cameras are the same in that respect) Normally (I don't know the canon) there is an indicator to tell you if the camera managed to focus. It can be a beep or a dot which light in the viewfinder. I suspect that in your case you were aiming at something lacking details.

My Vivitar Series 1 24-70 manual focus ais lens won't work on program in my Nikon FA. I bought both new, but have stored them for a long time. It works on aperture priority, shutter priority, and manual, just not in program. All my other lenses do, including other Vivitar lenses, so it must be the lens. Fresh batteries in the camera. I get the FEE message, which means the lens is not set on the smallest aperture, but it IS set on the smallest aperture. I have tried dismounting and remounti

My Nikon D3 is not firing when either of the shutter release buttons are pressed when the lens is attached. Both buttons fire when there is no lens attached. I have cleaned the contacts and the battery and the battery contacts. i have tried the lenses on other cameras and theyre fine.

Do the lenses auto focus on the D3? If not, try cleaning the contacts on the camera body with a cotton swab lightly dampened with rubbing alcohol. ... Nikon D3 Digital Camera

Canon Powershot A610 digital camera--LCD screen shows icons, but otherwise is blank--there is no visible movement in the lens when I take a picture without flash--have tried setting it on TV setting and taking a picture, then opening the battery cover for a few seconds after waiting 7 seconds or so, but no images on the LCD except the camera's icons--ideas? probably a stuck shutter, or is it still possibly the CCD sensor even though there's no visible movement in the lens? Ideas? Thanks!

Much more likely that it's a stuck shutter, especially for your model camera. How many tries did you give the fix? Some people stated that it took at least 15 repeated tries before the shutter opened:\015\012\015\012\015\012 ... Canon PowerShot A610 Digital Camera

Hi, I've a Sigma 28-105mm aspherical 3.5-5.6 lens. Auto focus does not engage. I can hear the motor trying, but the ring does not turn. When I switch to manual focus, I can turn the ring to focus manually, but I still hear the motor trying to use autofocus. Additionally, sometimes the shutter will not fire in manual focus while the motor is still searching. I've cleaned the contacts, but no joy. I suspect a faulty switch, but that doesn't completely explain the autofocus not engaging. I am

Well, I think you have at least one problem pinpointed, in that I suspect the focusing ring is jammed, and cannot rotate with the electromagnet signals. The other problem might be a faulty auto/manual switch. Of course, check for oxidation and e ... Digital Cameras

I have a digital canon rebel xt with several lenses. I just purchase a tamron 70-200 1:2.8 lens and want to know the correct setting to take footbal pictures at night from the sidelines. I get perfect daytime photos but still blurry at night HELP

An f2.8 lens is pretty good lens speed, which means that the size opening the lens can make to let light thru it. Try this out:\012Set you camera to at least ASA 1000 sensitivity then set your camera to 'A' or Aperature mode. Walk down to the ... Canon Rebel XT / EOS 350D Digital Camera

My wife has a Canon 60D DSLR camera. When she looks through the view finder, it looks like the lens has a speck of dust on it as she can see it in the viewfinder. She has swapped lenses and the spec is still there. She used the auto clean function for the sensor, but the spec hasn't moved, This is almost a brand new camera. Should we clean the sensor by hand? If so, how do you do it?

Take a couple of pictures, over a dark background, if you can see the spec of dust on them, the problem might be in the mirror. Now, if the dust does not appear on the pictures, it's either on the viewfinder, or somewhere else out of the way of the s ... Canon EOS 60D Digital Camera

I have a Canon Rebel Xti and today I was shooting pictures with a new lens and I pressed the shutter and it did not release and it is stuck. I tried to turn off the camera but it still shows that it is on. Thanks for the help

If the camera does the same without the lens mounted, it's probably a defective release switch. It'll have to be replaced by a repair shop for around $130. ... Canon Digital Cameras

Err 99 Doesn't matter what I have tried, I am still getting the ERR 99 code on my digital rebel. I have cleaned, replaced the battery and cf card, changed lenses, cleaned lens connections.

I have a Canon EOS T2 film camera. The shutter blades appear to be stuck half-open. I have checked with two lenses, it's not the lens. Have replaced the battery, no change. Any suggestions?

My Canon 5D mkI turns on ok, will focus, displays top and back, but it will not take a shot. I have two batteries, both which I have charged to full and tried (display shows full charge). I have also tried two seperate CF cards. I have tried cleaning all contacts. Still it won't take a photo. The shutter will work when I use the "clean sensor" function though. Also, I have reset all settings on the camera. Anyone know why the camera isn't firing off a shot?

A Canon A570IS will power on and and everything works with external power (3.5-3.7V, 2A. 3rd party) but is dead with batteries (two fresh alkaline or NIMH AAs). I have used parts (from junk 570s) and have replaced the main board, button board, flexicable that includes on/off switch & shutter, leds, etc.. Again, lens, flash, storage, LCD, etc. work with external power, but not with batteries. I am at a loss. Any suggestions?

Since the external power works, we need to know, first off, if the battery terminals have continuity with the external power supply contacts. That will tell us an important part of this puzzle. The one hard thing about this problem, is that what ... Canon PowerShot A570 IS Digital Camera

I have a Caonon 40D. I thought I was having a lens problem at first. However after using 2 other lenses I have found out it is my Camera. No matter how clear and crisp the image is in the view finder. After the photo is taken and loaded into PS4. The image is blurry and unsharp. I have reset all camera settings to factory with Canon. And I am still getting the same results. Any help would be appreciated. Thank you in advance.

It is probably due to dust on the sensor, or sensor alignment not properly done. In both cases you have to take the camera to a Canon dealer for servicing. ... Canon EOS 40D Digital Camera

I have a Canon Rebel Xt that occasionally has problems with the shutter button suddenly not working. The camera is still on and all the menu buttons continue to work. It acts like the lens decides to quit communicating with the camera body. The only fix I have found is to take the battery out for 10-15 sec. and it works like normal. Any advise on whats going on would be great, Thanks Brandon

I just purchased (about one month ago)a Canon 50 D with 28-135 is. Yesterday I recieved a Canon 2.8 IS L 70 -200mm. When I mount the camera to the lens ( the 70-200) I notice a little wiggle in the mount attachment. I went back and checked to see if my other canon and Sigma lenses do this on the 50 d and they do. I just seems more noticeable with the larger lens. Is this normal?

The larger lens is longer and the wiggle is the same amount of play but closer to the end of the lens it moves more due to it being longer/larger. Just insure there is no substantial movement at the actual connection or lens and body. It should lock ... Canon EOS 50D Digital Camera with 28-135mm lens
