Photography whether a hobby or a profession, every photographer wants his/her every capture to be perfect. There are different types of cameras and lenses available in the market. Each type has its own distinctive features. When choosing a camera and lens, one should consider his/her own needs, not the hype. There are many technical issues when it comes to choosing the camera lens. So, everyone should check a little before spending money.
What is a telephoto lens?
A telephoto lens is a special type of long focus lens. It is extensively used in photography and cinematography. Its actual length is shorter than the focal length. This is done by using telephoto group. It can improve light path and make focus length long in a shorter design. For same focal length, the view angle and other long focus lens effects are all same. Long focus length lenses can be designated as a telephoto lens, but this is incorrect.
There are two types of Telephoto Lenses
- Medium telephoto: lenses covering between a 30° and 10° field of view (67mm to 206mm in 35mm film format), and
- Super Telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format).
How to Choose Telephoto Lens?
People often says that “It’s the photographer that counts, not the camera”. But consider capturing a high-speed race car or a flying bird from a long distance with a slow moving camera lens. No matter how expert a photographer is, he/she will face some difficulties. So, it is really important to have appropriate gear.
Before you go out there to buy your telephoto lens, you need to ask yourself if you really need it. Are you really into wildlife photography? Do you really need this high-end features? If you are not going to use it up to its full potential, then, there is no point in spending more money. If you can get your job done at lower cost, get that one which is good enough for your needs.
The first thing people want with their camera is best picture quality. It depends on the glass of the lens. The better the lens, sharper the image will be. And more you spend on the lens, the image quality will be better.
Then you need to decide whether you need a prime lens or zoom lens. A prime lens has a fixed a focal length, but zoom lens can work over a range. Prime lenses are fast, but I think zoom lenses have the flexibility to be used over a range.
Nikon 200-400mm f/4 VR II or Canon EF 200-400mm f/4L IS USM are zoom lenses. The prime lenses come in 300mm, 400mm, 500mm, 600mm.
There are some budget friendly lenses available in the market like sigma, Tamron etc. You may not get competitive features like Canon or Nikon. But since you are paying low, you have to forgot something, right?
There are few other things you need to check. As the already mentioned motor speed of the lens is an important factor. If you have a slow lens, you can’t capture fast moving objects.
Then check the focus length. This is one of the most important factors of the camera lens.
