There are going to be plenty of
photographic opportunities when moving closer to your subject just
isn't possible, and in those times of magnification need you can opt
for a telephoto lens. A telephoto lens is available as both a zoom and prime (fixed) lens; it provides
higher magnification and is used to photograph something far away
because you either cannot get closer to it or you want to flatten the
perspective. A zoom lens with a focal range above 100mm is classified
as telephoto.
Years ago telephoto lenses that
produced very high quality images were not only difficult to create,
but very expensive. It's only been in the last decade or so that
manufacturers could bump up the quality without drastically
increasing the price. Telephoto lenses are popular among nature
photographers –it's not easy sitting right next to a lion after
all. Although it is traditionally used for wildlife and wide-angle
for landscapes, don't be afraid to swap.Additionally they are excellent for sports photography, another scenario where it is difficult to be close to your subjects. It's also great for
capturing candid shots, which tend to make the best pictures. The
lens allows you to isolate your subject, to truly make it the center
of attention.
The main obstacle to overcome when
using a telephoto lens is camera shake. While some lenses have a
vibration reduction mechanism, it won't completely solve the problem.
Not only do you need to shoot at a faster shutter speed to minimize
blurring, you should use a tripod whenever possible.
