Question about Canon EOS-20D Digital Camera with 17-85mm Lens

1 Answer

Not being able to shoot

Some 2 weeks ago as I tried to shoot with my EOS-20D w/ Canon's EF-S 17-85mm lens, it didn't "wanted" to shoot. I imagined being a focusing issue, so I switched to Manual Focus, took a picture and then back to Auto Focus. It worked well. But now the same problem appeared, which means that although the camera can get the subject focused (and the focus light gets solid, not flashing), it simply doesn't shoot. I already tried switching lenses and the problem remains the same. Battery fully charged and firmware is the latest version (2.0.3). Any ideas of what can be done in order to get it working? I'd appreciate!!

I just received the canon EF 100-400m lens for Christmas. I was using it on my canon EOS 20D and it just shut down. I thought I had a dead battery but even after charging the batery, I couldn't get my...

I've had this happen right in the middle of a shoot, what I found first was that I had pushed the lens release button and the lens moved ever so slightly but enough to mess up the connections and everything went dead. Another thing is not having the battery at a full charged but if it's not coming on at all I'd be checking the battery door make sure it's latched securely. Next make sure the Card is down and locked in the seat and the card door is closed and locked. Clean the contacts on the camera body and lens (this generally gives an error 99 though) with a red soft pencil eraser keep the lens as vertical as possible when lightly cleaning (polishing) the lens contacts. Keep the lens cavity pointing down as much as possible while cleaning (polishing) the body contacts another thing and my 20D is coming due for this as well is a back up battery this replacement is found on page 35 of your manual Oops not manual here is a diagram
Here is where to look and what to do diagram

This should put you back into the photography again Cheers Have fun with that great lens

My cannon rebel eos DS6041 displays error 99 when

'Error 99' indicates some problem with the AF contacts. This is a common error in Canon lenses. It could indicate a very simple problem like dirty contacts or a much serious one like the breakage of USM cable.
As a first step, you can try cleaning the lens and body contacts (the metal contacts between the lens and body) using a pencil eraser. Be careful to hold the body facing down so that no dust falls inside. After cleaning both the lens and the body contacts, re-attach the lens and try shooting. If the AF does not work still, you need to take the lens to an authorized service center.

I got error 099, before I was getting error 05. and the flash dos not open canon EOS 20D

I also get the error 99 message and cannot take any photos... I have been able to solve this problem by taking out the batterys and wiping down the connectors on both the batterys and the connecters in the motordrive with a lens cloth. keep the lens cloth on hand when shooting. It may be that either oils, or dirt has gotten onto the connectors. I hope this helps.

Hi all, I wonder if you can supply some advice regarding a Sigma17-35mm lens I purchased earlier in the year. Basically if I use the automatic or 'P' setting on my Canon EOS 30D camera the image is over...

Try your EOS in AV (aprature value) mode. You should be able to adjust your aperature value in 1/3 or 1/2 steps dependind how you have your Custom Functions set in your camera's menu. Possibly the lens you purchased is for an EOS 35mm. If you use a 35mm lens on your eos there are some calculations you must use. When using a 35mm lens on the EOS 20D, 30D, 40D and 50D bodies, you must first calculate your focal leingth by 1.6 times. With this, your exposure changes as well.

The only EOS Digital SLR bodies that use a 35mm x 24mm CMOS sensor are the 1D and 5D. My wife uses a Tamron 18-200mm f3.5-5.6 lens on her 20D and loves it.

If this makes no difference, you may have a defective lens.

"busy" Error

check your firmware version and update if necessary. Usually you get the "busy" message when your camera is writing to the card and it's possible the card isn't quite right - a format should fix it. Alternatately you might try a different CF card to see if the problem goes away. Good luck!
