Skills of using telephoto lens

After a period of exposure to photography, I believe everyone must have the desire to use telephoto lenses. The shallow depth of field, the sense of spatial compression and the ability to shoot a longer focal length brought by telephoto lenses are all reasons why people like telephoto lenses. Here are some tips I shared on using telephoto lenses. Let's have a look.

1. Make sure that the shutter is above the safety shutter.

In addition to shooting portraits, telephoto lenses are often used for ecological photography, landscape photography and other subjects. In order to ensure that the film does not paste, we first need to use a relatively safe shutter value to shoot. In fact, each lens has its own safe shutter range. At present, the accepted calculation method is "1/ current focal length". For example, when shooting with 200mm, the slowest shutter value will be 1/200 seconds.

If the camera body or lens has shockproof function, it's better to turn it on, because anti-shake can also compensate the shutter, which means that we can use the shutter speed lower than the safety shutter in special circumstances to ensure that there will be no jitter.

However, different camera bodies or lens compensation, shutter series is different, or you should make a good calculation in your mind.

2. The cropping/cropping mode is also a good choice.

Does the telephoto lens choose APS-C or Quan Huafu? It depends on the theme. However, sometimes a truncated camera is paired with a telephoto lens. The effect will be better. For example, when the focal length is not enough, the telephoto lens of APS-C camera will be multiplied by the lens coefficient, and the focal length of intangible media will be increased (Nikon and Sony are 1.5 times, Canon is 1.6 times). For example, APS-C camera shoots with 100mm lens, and the equivalent focal length is actually160 mm..

In addition, at present, some full-frame cameras have the mode of opening APS-C frame editing. After the APS-C frame clipping mode is turned on, the viewing angle becomes narrower, but the area of the corresponding focused frame becomes larger, which can almost fill the entire viewfinder, making the focused coverage area larger during the focusing process, which is more conducive to snapshot.

Therefore, for people who like eco-photography, it may be more appropriate to choose APS-C, because it is also a telephoto lens with APS-C format, which can shoot farther scenes, which is very beneficial.

3. Increase the ISO value

Because the telephoto lens has a long focal length, the safety shutter will be faster, often faster than 1/200 seconds. Because the shutter is faster, if other settings remain the same, the photo exposure will be reduced. If the maximum aperture has been opened, normal exposure can only be achieved by increasing the ISO value by one or two levels. Now the performance of ISO800 SLR camera and 1600 is excellent, so you can safely improve the ISO value.

Use tripod to avoid shaking hands.

We will find that telephoto lenses are basically equipped with tripod bases, which shows that manufacturers actually recommend us to use tripods. Needless to say, the advantages of tripod can save a lot of effort. After all, the weight of telephoto lens is relatively high. Moreover, the tripod can better place the blurred photos caused by hand shaking, so don't be stingy with the tripod when you go out to use telephoto.
