How to take Sharp photographs using a zoom lens

When using a large zoom lens, the very first step is to use a sturdy tripod. Telephoto lenses magnify camera shake (the more you zoom, the more you magnify camera shake), so it's essential to use a sturdy tripod to keep your camera stable. A tripod with a good ball head or gimbal head can help you make small adjustments to your composition without moving the camera. However many of these can be on the expensive side. Id recommend a good starter tripod like the NEEWER 77 inch Camera Tripod Monopod for DSLR with 360° Panoramic Ball Head.

Another method of taking tack sharp photos is to avoid touching your camera altogether. By using a remote shutter release or cable release you can bypass camera shake caused by body movement, and help you avoid camera shake caused by pressing the shutter button. Alternatively, you can use your camera's self-timer to delay the shot by a few seconds, giving the camera time to stabilize after you press the shutter button. However, this isn’t all that practical when photographing wildlife as they will not sit still and pose for you while your camera is waiting to take the shot.

Keep your shutter speed high. Using a fast shutter speed will save you a lot of heartache. As it has been mention before, telephoto lenses are more susceptible to camera shake unfortunately. So it's important to use a fast shutter speed to freeze motion and minimize the effects of camera shake. As a general rule, try to use a shutter speed that's at least as fast as the reciprocal of the focal length of your lens. For example, if you're using a 200mm lens, try to use a shutter speed of 1/200th of a second or faster.

For those of you who are wealthy enough, use image stabilization. If you own a higher end camera, or lens, you more than likely have image stabilization or vibration reduction. So if your telephoto lens has built-in image stabilization, use it. This can help compensate for small amounts of camera shake and allow you to use slower shutter speeds without sacrificing sharpness. Although it has been documented that sometimes image stabilization can actually cause blurry images. I would recommend anyone to use it as needed, and if you can take great shots without using it, to leave it off.

Using manual focus is another way to get you images sharper. Autofocus can sometimes struggle with telephoto lenses, especially in low light or when focusing on distant subjects. Using manual focus can give you more control and ensure that your subject is in focus where you want it to be. However, a good trick to use when you can’t quite focus on your subject is to focus on the area around it. For example, if you can’t get a little bird in focus, instead of wasting precious seconds trying to focus on the bird, focus on the branch or tree the bird is resting on. Then make your way to the bird as your camera will have a much easier time focusing on the bird now that it is more in focus.

Make sure to check your aperture. Using a wide-open aperture (such as f/2.8 or f/4) can give you a shallow depth of field, but it can also make it more difficult to get your subject in focus. Using a smaller aperture (such as f/8 or f/11) can increase your depth of field and make it easier to get everything in focus.

Consider using a lens hood: A lens hood can help reduce the amount of stray light entering the lens and can also help protect the front element of your lens from scratches and other damage.

By following these tips, you can improve your chances of getting sharp photos with a telephoto lens. Good luck to you all on your photography journey!
