Anyone familiar with this or have advice? I was out shooting a senior today and was using my zoom lens (Canon EF 28-135mm F/3.5-5.6 IS USM) and suddenly started getting Error 99. Sometimes it would work on certain settings, but usually when I switched it to manual it would give me the error, it seemed to work only in the portrait mode but wanted to pop the flash up, which i didn't want outdoors, so I would switch it back to manual and it would give me the error. My other lens worked fine. I checked the manual and it mentioned that error could have to do with using a non canon lens and to take out the battery pack and put it back in.

Could this be a serious problem??? Or do I just not know how to use my equipment???

(I also have a vertical grip battery pack, and the batteries did get low by the time I was done)

I had a similar problem, I looked all over the net and MOST err99's are due to bad contacts between lens and body, its suggested using a rubber (I guess an eraser if you are american!) to wipe the contact on lens and body to remove grease etc, I hope that sorts it out.

Err 99 also seems to be a 'catch all' error, so if there isnt an appropiate error message it'll just give an error 99. With my camera it was because the mirror had an intermittent fault, so I had to send it back to canon.

I hope you sort it out dood!!!
good luck

Thanks! I'll try the eraser thing. I am also re-charging both batteries and hoping it will work just fine for next weekend (I have a wedding to shot and really will need that lens). Just in case, what are people's back up suggestions if I don't have a zoom lens, can you rent them on short notice or anything?

I started getting Error 99then a couple of weeks later it would take one shot and then switch itself off. It turned out to be a faulty top control connector assembly. his was covered under the warranty but i was without my 20d for five weeks. Hope its not this!

I have had the odd error message that I think I fixed by making sure that the vert. batt. grip is firmly secured - it was half a turn loose. I say "think" only because I also jiggled the lens, switched the camera of and on a few times and generally fiddles with it first. However, I am pretty sure it was the vert. grip that was causing the problem.

For a wedding, if you are the main photographer, you might want to make sure that you have a backup body as well as lens. As it is not my job and because I cannot justify buying a digital body backup, for these types of event I take my old film camera and a few rolls of 35mm, just in case: better than nothing! You can pick up a film body up for a few pounds/dollars nowadays. Just beware that you cannot use EF-S lenses on it (ie make sure that you have at least one full frame lens on you as well!).

A general comment on cleaning contacts from an electronic tech. While using an eraser is an excellent tool for cleaning contacts I would not recmmend it around a lense opening due to the potential for bits of rubber inside the camera. A much better, and just as effective a tool, is a dollar bill. A very light scrub will clean oxidation off the contacts. Don't forget the contacts on the lens too.

Yup, I've had the same problem from time to time. Most of the time for me it was when I had the same lens (28-135) and grip on there, using the camera on a flash bracket at an event, and when rotating the camera on the bracket. No big deal, just unscrew the grip about halfway and re-tighten. I don't really use that lens anymore, but it does happen considerably less to me with an "L" lens on there now for some reason.

I've been meaning to try putting a couple of those thin felt stick-on "tabs" in between the camera and grip to act as a shim and keep everything tight together. Theoretically, it might work. The screw does get loose over time during use, but I've gotten in the habit of using my left thumb to make sure it's tight every so often while shooting.

I get this occasionally on my 100-400 L IS.
It is usually when the batteries are low and the IS is sucking too much power.

Try new batteries

Thanks! I think the vertical grip being loose might have been it (or low batteries), but I did test the lens on another 20d body and the first shot gave the error.

I ended up rented a body and lens, but never used the body, the rented lens worked fine on my camera, even with the vertical grip, however after my event, the "trouble lens" also worked on both bodies when testing. I just sent the lens back to Canon because it's under warranty but now I am thinking the comments about low batteries and loose vertical connection makes more sense and I'll just have to be aware of that.

In the process, I ended up buying the used lens I rented, so now I have a new zoom (Tamron 28-200 mm 3.8-5.6).

During this even my batteries ended up running out! This has never happened since using the double battery grip, luckily the rental had two batteries with it that I had charged the night before just in case. But now I am wondering if my batteries have lost some of their charge? They have never run out that quickly before and they have been re-charging pretty quickly.
