Was shooting with my 6D and 24-105 on a tripod. Several shots were excellent and then, all of a sudden, this happened. I know something is amiss, but the only thing I can figure is that I left the stabilizer on while using the tripod. Error on my part. Looks as though the lens just stopped focusing. Any other suggestions would be appreciated.

Try to recreate what happened by shooting 1 object without the I/S or VC on and then reshoot the same object with it on and check the results would seem to be the quickest and easiest solution to eliminate 1 possible problem.

Good thought dooragdragon. Will try that, but my subjects have left. When they return, will do it. Also, I plan on also changing lenses to possibly an 85 which does not have stabilization. BTW, when I took the camera off the tripod, it worked beautifully with the 24-105, but, alas, my subjects had flown the coop.
Thanks

You don't need a real subject any object will do for this test , be it a tree or a card board box, just something to focus on and shoot.

The problem with the posted image has nothing to do with IS, its just terribly out of focus.

That lens needs the IS turned off if it is mounted on a tripod. I had this happen, the lens began to search for focus and kept re-focusing. Most lens are designed to so that IS should be off when the lens is tripod mounted. :) :) :)

Exactly. :thumbup:

I have seen this myself, in my case it was a fly that flew in front of my camera just when I took the photo. Auto focus lenses are so sensitive it's amazing what fine details they can focus on.

If I were shooting a stationary subject with my camera on a tripod, I would use manual focus.

Have to agree with MT shooter on this. Autofocus needs to pick up differences in contrast to work properly and I'm guessing that the dark area in the middle of the picture didn't give it much to work with.

If it was a stabiliser issue you'd see it quite clearly at screen size, and probably on the back of the camera if you use the zoom feature. In my experience you'll usually see a slight blur in either the horizintal or vertical planes rather than a general all round shake type blur.

Thanks all for the great responses. I believe it was likely the lack of contrast that caused the problem. Did it again later and the same thing happened. Switched lenses to my 85 without stabilization and all was well, although I really don't think the lack of stabilization was the answer. I did, though, change the focus from spot.

It doesn't look to me as motion blur but rather mis-focus.

Do you have a freind or camera store nearby that has a camera that will accept the lens in question to see if it does the same for them so that you can rule out a malfunctinong lens ?

When I make use of a tripod I turn the IS to the OFF position. There are two (2) reasons for this .. One you can see by your photo posted and Two, the battery life is effected as more power is pulled from the battery.
By turning the "Auto-Focus" off just after the focus is made you can also elevate the change of "something" causing the camera to re-focus. Or as Steve suggested, use Manual Focus.

Then there is the chance that there is something wrong with the lens... But IF it were you would have more than one shot effected.
