Joel, thanks for viewing and commenting.


I was using a 40D + 400mm f/5.6L comboso the focal length is 640mm.It was about 6 pm and the coyote was in the shade so even at ISO 3200 I could only achieve shutter speed of 1/500 sec. The rule of thumb is that you need to haveat least ashutter speed of 1/focal length to avoid camera shake. In this case 1/500 isslower than the recommended speed. Reducing the ISO would slower the shutter speed and put me in much more risk of getting unsharp images.


You can never get the same moment twice in wildlife photography, therefore you need to be sure of getting a good imageevery timethe photo opportunity arises.Iwould rather get a noisy image than a blurry image. Noisy images can be fixed using a noise removal software, but blurryones are useless. []
