Action from your subject demands swift reaction from you. A fast shutter speed is a priority. Your camera should be able to handle 1/2000 sec. A small aperture provides an imagined expanded depth-of-field but the combination of these settings dictates dialing-in a very high ISO, something which your camera does not excel at, nor mine either. However, you have the supreme advantage of having a super long telephoto (600 mm) and probably some form of superpower that makes you more productive per unit time than an entire retinue of nature photographers. With magnifying power comes the relative independence from cropping, something a 200 mm lens cannot be without. The noise and global image degradation associated with very high ISO capture, a shortfall of entry-level DSLR cameras and even of cropped sensors (APS-C) in general, becomes horrendous only when an image is heavily-cropped to mitigate the shortsightedness of a medium telephoto lens deployed in this manner. If the action shot does not need heavy cropping then the high ISO sandpaper effect is much less objectionable. So, try your highest shutter speed, at ISO 1600, at f11 and see what happens. I look forward to your success. Heck, I look forward to just seeing more of your posts. There are too few posts on tis forum. I’ve seen more posts in a farmer’s field.
