water park

Took some photos at a water park yesterday. I was shooting shutter priority set at 1/1000 and using a 7o-300 zoom lens. I was disappointed that about half of them came out blurry. I'm guessing that given the lens and subjects that I should have used a faster shutter speed. Am I guessing right? Paul

1/000 of a sec would stop 90% of normal action. I'm thinking with the shutter set that fast the aperture would have opened up to let in more light so shallow depth of field = blurry shots.
Try going back to the park with aperture priority set to 1/400 and compare...

Your focus mode could be a problem. If you were in af-c mode with the default of release priority, you need to be sure focus was achieved. In that mode the camera would let you trip the shutter even if it was not done focusing if you were a little quick on the button. If nothing seems focused, this could be what happened. Maybe post some so we can see.

What, exactly, was blurry though... Was the subject that was, presumably, in motion blurry while the rest of the frame was sharp, or was the entire frame blurry and out of focus including the moving subject? Also, what focus-mode were you using? AF-C set to "Release Priority" will allow the shutter to fire even when the camera has not achieved focus-lock; it's up to you to confirm you have focus lock before taking the shot when using this AF-Mode.

This is why example photos are helpful; we could probably tell by looking at one of your shots, and the EXIF data, what the problem most likely was.

This is one of the more blatant of the pics-data is= F5.6, shutter speed 1/1000,iso 320, focal length 300mm, meter mode pattern. thanks, paul

I would say that is out of focus, not shaky. Almost certainly a result of being quick on the shutter button with release priority set. A few fixes... pause briefly while the shutter button is halfway to give the lens time to focus. Or set focus priority. You can set release priority or focus priority independently for af-s and af-c. I think the default is af-s set to focus priority and af-c set to release. So see if you are using af-s or af-c and set it for focus priority. Menu A1 or A2.

Hmm. If you are getting a beep, that tells me you are in af-s mode with focus priority.That is not the norm for bbf setup. Some guys do use it that way, but you don't get the full technique. They have their reasons for doing it. Anyway, using af-s with bbf will lock focus once achieved, beep-locked. If you continue to hold the button, focus will not update if the subject moves. You would need to release the button and press again if the subject moved. Does this sound like something that could have happened? That is, the subject moved after the beep but you were still holding the bbf on. That is my new guess, that focus halted because of af-s and then the subject moved out of focus. If you set af-c with release priority, it will follow the action and try to keep focused as long as you hold the button down. The only pitfall is a quick first shot when the focus has not had time to settle could come of not focused.

Are you sure you are even in an autofocus mode? This looks like pictures I have taken when I accidentally moved the AF/MF switch to MF mode.

Ray got what happened right -though I did research to learn what auto- focus to use, I set it for af-c but after his reply I checked and somehow it reverted to af-s. Thanks guys for all the helpful replys-and Brent, I actually did exactly what you said, one time not long ago and it took me some time to discover!! Paul

Here's one I took at a water park. I went a slightly different route. I bumped the ISO up a bit to compensate for the higher SS.
