Photography Question

Blurring at full zoom


I have a Digital Rebel with 3 lenses, 18-55mm, 75-300mm IS, and 28-135mm IS. I have noticed recently while photographing wildlife that my 75-300mm rarely takes sharp images at full zoom. It happens with or without filters, at shutter speeds up to 1/1000 and on manual and auto-focus. I checked the other two lenses under the same circumstances and got similar results. Images always seem to be sharpest at only the widest angle. Am I doing something wrong? Is there something wrong with the camera? The 28-135 is new (less than 100 pictures)and the other two have been cleaned. What can I do?
