Hi...I'm trying to get a picture of an 8-week old Golden Retriever jumping through a tire. No question that the tire is in focus, but the little jumper is not. Have ISO at 1600, f/4, 1/100. Looking at the numbers, I know that the shutter speed is not nearly fast enough, but how do I increase the speed? How high can I go with ISO? Have no idea how to slow down the puppy!
I'm trying to upload the picture to my portfolio so I can post it here, but it's not uploading. Life is a series of frustrations!

It looks like the 7D will go up to ISO 6400.
What kind of lighting are you in that ISO 1600 at f4 only gives you 1/100 shutter speed? |

Judging from the settings you have very little light to work with. You are fighting both narrow DoF and movement. If puppy is not perfectly aligned with the plane of focus, you'll get one kind of blur, and if (s)he is, but moves during the exposure, you'll get another. You may get one or both.
You are correct that 1/100 is not fast enough. For that kind of action, I would start at 1/500. But that loses you two stops of light (plus a little), and cranking your ISO to 6400 to compensate is going to be, well, noisy. And there is still the narrow DoF problem.
So the ultimate solution is to add light, at least three stops of it, then boost the shutter speed and close down the aperture a little.

| I'm taking the pictures indoors during the day. I was thinking exactly was you guys are suggesting. Can't add light so bumping ISO and/or using a faster lens might be my only options. Or, I could wait for the puppy to get a little older and jump with more thought and less speed. |

Can't add light? Bummer. Is this a competition or something?
Seriously if you can't use a flash (By far the best choice), then I suppose it's probably time to buy that 85mm f/1.8..
Assuming that you could use a flash, I'd just set one up on a radio trigger somewhere near the jump.

Could you use your 50mm/1.8 or your 85mm/1.8 or your 100mm/2.8? Are they enough lens?

| No chance of shooting outdoors, sunlight will fix all of your issues. |

I suppose I could use either the 85 or the100. Might be the best option I have. Can't use flash when a dog is doing agility because it distracts them and can be dangerous to the dog. |

Ok, so it is a competition.
Yeah, that's a real challenge. The 85 f/1.8 and the 100 f/2.8 are both much better options, unless you can talk the organizers into setting a spotlight up.
Otherwise, use something with a good IS system, and set it to mode II (if available, for vertical-only IS), and then just go for a lower ISO, something that will give you 1/15 or so, and just track the dog - sometimes the results are surprisingly good. It is, however, a very much hit and miss (mostly miss) sort of technique. |
