Choosing a good lens for a camera

Choosing a good lens for a camera

Choosing a lens is quite a serious task, both for a professional photographer and for a beginner. The fact is that there are a lot of lenses, their names are marked with different letters and numbers. That is why it is very easy to get confused and make the wrong choice. The numbers that are indicated in the name of the lenses are their main characteristics - focal length and luminosity. In order to help you choose a lens for a SLR camera, below will be a description of all its parameters, but if you do not have time to read all this, then I advise you to watch this video.

Specifications

Focal length

This parameter is measured in millimeters, thanks to him you can understand what angle of view it has and how much it can approximate. Among the lenses of various systems you can find focal lengths in the range of 4.5 - 1000 millimeters and more.

Depending on the value of the focal length, all of them can be divided into:

  • super telephoto lenses: 300mm or more,
  • telephoto lenses: 50-300mm,
  • standard lenses: 35-50mm,
  • wide lenses: 18-35mm,
  • ultra wide angle: 4.5-17mm.

Luminosity

In the middle of each lens is a diaphragm, which consists of petals. Compressing and unclenching, the petals allow you to adjust the diameter of the hole, through which light enters the inside of the lens. As a rule, the aperture value is indicated by the number: 1.4, 2.8, 3.5, 4.

Aperture ratio is the most likely relative aperture value for a particular lens.

The aperture value is considered one of the main characteristics that affect the exposure of a photograph. From this, we can conclude: the higher the luminosity value, the lower the illumination it will be possible to take a picture without fear of blurring the resulting frame. In addition, the depth of field depends on the aperture.

Fixed or zoom lens

zoom

zoom

Zoom lenshas a variable focal length, which allows you to change the viewing angle, i.e. zoom in on the image. Zooms are more convenient compared to fixed lenses, since they have the ability to zoom in on an object to be captured without getting off the ground.

However, it should be noted that zooms are much more complicated in their design than fixed ones, since they use more elements that move relative to each other. In order to buy the most suitable model, do not forget about the additional parameters of this device.

Image stabilizer

Image stabilizer is located inside. It allows you to compensate for hand shake during shooting, so that the picture will not get smeared even during shooting in bad conditions. This is a great device that helps to make high-quality photographs in poor light conditions, as well as with long exposures of shooting. However, the presence of this device makes its cost significantly higher.

Focus motor

In order for automatic focus to work, you must have a motor. As a rule, in inexpensive models the mechanical motor is used. Focusing speed is not too high, and it buzzes during use. Fast and almost silent option can be called an ultrasonic motor.

Bayonet

In conclusion, I wanted to draw attention to this concept. Bayonet called the method of attachment to the camera.Each lens is suitable for a certain camera of a certain company, but there are adapters with the help of which you can get around it if a competitor’s company has a super cool lens that you need. Surely, everyone understands that the most famous competing firms: Canon and Nicon are completely incompatible with each other.
