Start here.
However, here are a few things. Set your ISO to 100, and use shutter priority (Tv) and a shutter speed of, say 1/125 sec. Make sure your white balance is set for the actual lighting conditions (sunny, shade, coudy, etc.) Use spot metering. Take more pictures! |

use servo AI for focus as the bird is moving.
A smaller aperture (higher number) will give you a larger depth of field, but the shutter speed will be slower. If you shoot in raw mode, it's easier to adjust the picture after the fact. Generally speaking there's more data to recover from underexposed areas than from over exposed. You could have under exposed by a stop or two (exposure compensation) safely with a white bird. |

A faster shutter speed will help make the image sharper. Especially when using long glass like a 300mm. Posted Via AR15.Com Mobile Look at how crisp the Egret shit was in the first picture. The image was taken with a pretty low ISO at a pretty fast shutter speed. I feel that the whiteness of the bird is causing problems. |

First off, you have a 70-200 f/2.8, use that for reaching.
The slower 75-300 f/4-5.6 is not going to be able to get the same sharpness and resolution of the faster glass. You can always crop, but you can't always get it sharper. Especially with moving targets. Watch your light meter, and adjust the shutter speed as necessary. I run around with the aperture set for the most part, and rely on shutter speed for proper exposure. Oh and don't center your subject all the time, try to show where the subject is going or came from a little more. |

I'm still learning. Also the 2.8 belongs to a relative and I might just be a newb but pics at the same distance cropped seem to be about as sharp as the 300mm lens. |
