I'm just PP these soccer pictures and the one right before this was f/3.5 1/4000 but the ss on this dropped down to 1/160. Shooting AV center weighted +1/3 EC, RAW. Is this one of the issues this camera is having? I didn't drop the ss and this was a game at 2:15 and I have noticed a few oof shots, not backfocusing just oof. 530xxx body.

I wonder if I should contact Canon and send them this or if maybe they have already gotten around 100,000 of these already?

I think the light meter in the camera caught a dark portion of the jersey and exposed according to that. When I shoot sports or mostly action stuff I use the shutter priority mode. Sure having the 3.5 might produce a really nice backdrop bokeh, but having the camera in 3.5 on a sunny day IMO is asking for a situation like this to happen. Here's what I would do:

Set your camera to shutter priority (Tv) and set the shutter to something like 1/1300. Camera will adjust the aperture accordingly to achieve the desired exposure.

Don't think I would send in to Canon just yet.

Good luck..

How would changing to Tv mode help the situation, both are setting one variable and the camera sets the other. If the problem was that the camera metered off a dark portion wouldn't it result in the same effect, just with a 1/1300 and say f2.8 vs f8?

I have some of these too, have not given them any thought as of yet. Must keep an eye out for it now that you've posted these.

John,
I had the same problem, maybe not to the extreme of your example. Where you shooting in high speed continuous mode? I was told to set C.Fn IV-1 to 2. Don't know if that is the solution, but it seems to be working so far. Tony

Obviously it's hard to tell but it doesn't look like there is anything in that image dark enough to throw the meter off that much.

After thinking about it, I have to agree..

I want control over my lens opening and rarely go into TV.

tmarcus I was in AI Servo when I shot this and I'll look at that CF you mentioned, the sun was above but behind me and I had many oof shots. The camera has been perfect until yesterday and I'm up to around 10K shots on it, don't know if that would mean anything but thought I'd mention it.

John, one other thing, I only seem to get variations in exposure with the 70-200L. What lens did you use? Tony

John, I shot a rugby game with the 1D3 2 weeks ago, 2K frames in 90 minutes. I was shooting wide open on a 300/2.8 IS in good light and the light levels never dropped. I probably got maybe 10 or so images like this. I never thought too much about it until I read your post....

I agree...even the darkest area of that image is over exposed.

And he was shooting center-weighted average, not spot or even evaluative, so one small patch of anything should not cause this.

There's essentially no logical explanation for this, other than gremlins.

Greg I wonder if it is the center weighted, just got done shooting some tennis and boy oh boy the exposures are all over the place on some of those but not as bad as the one I posted. Could I have metered of that player then moved the camera just a bit so that it metered something else causing this? Never had this problem using Eval. I have a soccer match tomorrow and I'm going back to Eval to see if there's a problem. I also have the highlight tone priority enabled. I don't feel like pp these shots now so maybe I'll post a couple of examples again in the morning. Just wonder if it is center weighted that's doing it. Or maybe it is those darn gremlins hahahahahaha

It is nice that nobody is trashing Canon over this (that has been done plenty over the past couple months), but every time I see a thread like this I am glad I am waiting to get the MIII and hope that Canon is successful in working the kinks out of it. I really want a MIII, but am still content to hold off and see what happens.

I really don't think so. I shoot center-weighted all the time--as did everyone else many years ago--and I never get anything like this.

Then again, my camera has one less "Mark" than yours.

Sorry I have to ask this, not sure if there is any relevancy to it but I need to know. The people that have been getting shots like this, what firmware version are you guys on?

I really want to get this camera(I had one sent it back, passed on two others) but more and more problems keep popping up with no official response from Canon. After dealing with the 1D/1DN I really don't feel like taking the chance that they will fix it. I hope it works out for all of the photographers that rely on this tool for their business. It's a tough camera to sell used and many had to sell their other cameras to purchase one.

I can tell I'm not the only one that is hesitant. There are hardly any used 1DIIN's out there and they haven't dropped in price.

I got the camera 3 weeks ago today and it was loaded with the newest version, whatever that number is. I'm thinking what happened at the tennis match yesterday may have been my fault but that pic from the other day was all the III's fault

Going back to Eval for today's soccer match but it is a bit overcast today. I'm not going to dump on the camera because for the most part it's been perfect and I'm confident Canon will get a fix for it's problems.
