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!!

    thanks, but none of this is the case. don't have the battery grip, cf card is well fit... anyone else has some clue?
    I must mention that I also re-formatted the cf card from the camera. It didn't help either.

    The 20D camera as originally sold had occasional lock-up problems (became unresponseive to user input) often right after changes lenses and/or flash cards. Removing the battery and re-inserting it restored the camera. Canon's 20D firmware update 1.0.5 fixed the lens-communication and CF-card communication problems in most cases, though some people still report lockups. Firmware 1.1.0 added a fix for horizontal banding at high ISO settings when using the built-in flash. There is a link for firmware downloads below under "Canon Links".
    Note: if you are using the BG-E3 accessory battery grip with a heavy lens, the grip can pull away from the camera body enough to release the microswitch by the battery door that locks out CF memory access. This could cause any number of problems if it happens while writing to the CF card. This can be fixed by using a folded-over business card, adhesive velcro pad, or the like on the far edge of the grip, to the outside of the locator-pin near the attachment thumbscrew. In this way the grip is "pre-loaded" against the camera body when it is screwed on, and no reasonable amount of force will open the microswitch. The same thing can happen with the CF access door if it is pushed slightly open by your right hand palm (less than 1 mm does it). One solution here is to cover over the door with another surface. Black gaffer tape is one possible, if crude option.

    Holding the MENU button down for 8 seconds continuously will hard-reset the camera, restoring all factory default settings

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

My lens is locked and i cannot zoom


I had the same problem with the same lens. Over a few months it got lose, eventually getting so sloppy that it dropped if my 40D was held down. 10 days ago it jammed and the zoom was locked. I sent it to Canon and received it back in a week and it is now like new. Please don't try and fix it leave it to the experts at Canon. Not sure what the cost was as mine was still just under warranty
I think that this is a common problem with this lens and beleive that something in the lense works loose and eventually drops into the mechanism.

00 on the F info (aperture shows 00)


I'll assume the lens is an AF lens? Most of the new Canon bodies require AF contacts. If there isn't the right contacts, it won't work. There are suppose to be AF body mounts that will tell the body that there is an AF lens, then use the old lens in Auto mode.
If it's an AF lens, the internal electronics are toast. You could send it out, but they'll charge you a "look at" fee. That could run into many bucks. Give Canon a call.

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!
