Canon 10D - 70-200L IS - Getting Error 0 and lockups

[mccrackenphotos]

Has anyone had a bunch of lockups using this same gear and then Error 0's for msg?

I've started to experience this today - the gear is 30 days old...and only started today.

To resolve, I have to turn off camera, disconnect the lense, remount it, turn back on. Then it works fine.

Problem was very intermitant but happened about 8-9 times today.

Looking for clues.

Thanks,
B

I haven't experienced this myself but there have been other threads on here about similar problems.

Make sure that the contacts between the lens and the camera are very clean.

I expierenced the same problem two weeks ago on a shoot with the 10D/70-200 IS. I Popped the batteries out for a second and turned the camera back on and the problem was cleared. (My backround as a Microsoft engineer)

On my camera, I am still looking for the keys for Ctrl-Alt-Del.

I had this problem last summer. It seem to happen only when I used IS, and the light was low.

I had to send it to Canon. The lens was not making the contact needed to function properly. It worked fine but again it started. I think in my case it is the lens. It has happened on my 10D & MKII.

If it happens a lot I will be sending it in with the 10D.

Pay attention to when it happens and if I were you I would send it to Canon. The sooner you send it the faster you will get it back. You can try cleaning the contacts on the lens too before sending it in.

Good luck.

It sounds like you have a problem with the pins that transfer information from lens to camera. Sometimes a little residue from your sweat combines with dust and insulates a contact.

Take an eraser and "erase" the contacts on the back of the lens as well as the pins inside the camera. Be careful to not get any eraser bits inside the mirror box of the camera or you'll have other problems!

Try that and see if it helps. And then keep your sweaty little fingers out of there! :D

Same problem on the D60 with that lens...
I chaulked it up to the connection between the camera and lens.
Seems to happen when I put it under some strain.

It required a reboot with battery removal....

I have had the exact same problem, and not only with the 70-200 lens. It was pretty scary the first time it happened in the middle of a wedding. Usually turning off the power, loosening the lens and snapping it back into place fixes it for a while. Regular cleaning of the contacts on both the lens and the camera body with alcohol and a lint free cloth have prevented the problem from returning.

The problem with this is that the gold finish on the contacts is very thin, and when you take anything like an eraser to it, you will slowly polish off that gold. The result is an even worse connection than what you had before.

I always found it best to study the gold contacts on the lens and on the camera, and use a magnifier, if necessary. You will spot the springloaded pin that is slightly different from the others. Sometimes those can be rotated 180 degrees and the problem goes away, and you still have your gold finish left.

In other words, Bob, you're saying not to use my Dremel on it? :wink:

(Insincerity alert!!! Notice use of winking emoticon---only kidding!)

Wassa Dremel - can you get one in L? :wink:

Just got a 70-200 f/2.8 IS and had the same problem described at the beginning of this thread. Sent it back to B&H and hope the replacement works! A little frustrating to such an expensive lens!

Ok, this will be off-topic...

Your kidding about the last part for sure, but if you don't know what a Dremel is, it's the "all-in-wonder" tool for electronics-work and PCB's. Much like the so beloved shift-wrench in mechanics =D Except that a Dremel actually works very good :) Don't come in an L-version I think, but sure is _THE_ "L" of all the tools I used for electronics at school. If I where only to keep one tool, it'll probably be either the Oscilloscope or the Dremel. Probably the Dremel, as you can have so much fun with it in boring classes =D

Oh, and the Hischerman's are real great to! It's small "normall-closed" clamps with needle-thin "grabbers" to grab around small electric pins. I was almost thrown out of high-school twice a couple of years ago (one year apart each episode) because of those Hischerman's + somebody else's ear :D Or not exactly because of that itself, but what followed. The first time the other guy electrocuted me just as the teacher came into class, and man did he freak out :lol: He was _this_ close to be thrown out of school for good, and when he heard exactly why I had been electrocuted, he wanted to expel both of us for three days.. Anyway, it didn't happen, and of course, we didn't learn :twisted:

So one year later, I did the same thing with the Hischerman on someone else's ear (and believe me that hurts). He chased after me through the classroom (teacher wasn't in), and reached me at the end. He then throwed into the wall of the teachers office (he wasn't in the office either at the time).. But.. he actually didn't throw me _into_ it, he threw me through it :lol: We survived that episode (barely) too.. God I hope I never grow out of my irresponsibility :roll:
