Cheers guys. I've never been that happy with the results at higher iso settings so tend to keep it at 100 as much as possible. The second shot there was at 1/400th so shutter speed/iso wasn't the problem.
I disagree, 1/400 is far too slow for stuff splashing about in water with a 300mm lens

The more I look at it the more I think the focus is a bit out and that's probably down to using AF-C, the focus point has caught a wave perhaps.

Getting focus right in these situations isn't easy, but you can increase the number of keepers castl;y by setting shutter speeds and ISOs accordingly.

There's no need to worry about noise at higher ISOs, these days. Noise can easily be removed but camera shake motion blur etc cannot.

You've probably got loads of great shots that would have been keepers with a higher shutter speed and ISO

I also just noticed you're using f7.1. shots like this would benefit from a narrower DOF. The DA*300 is a great lens and would look fine at F/4.0


For a shutter speed of 1/2000 and F/4.0 your ISO for the same exposure ( 1/400,f/7.1,ISO100 ) would only be ISO160

but even if you keep the Aperture to 7.1 you'd still only need an ISO500 to bump up the shutter to 1/2000


This is a good calculator to compare settings for various EVs
