Having a good camera, at first you can be satisfied with the standard lens, but there always comes a time when it becomes insufficient, it seems as if you want something more. In such cases, few people think about buying a new camera, but many people think about replacing the lens. When choosing a photo lens, you need to pay attention to the following characteristics.
Instructions
Step 1
First, remember that not every lens is suitable for a particular type of camera. Many manufacturers specifically make their cameras incompatible with lenses from other manufacturers. For example, Canon uses Canon EF mount, Nikon uses Nikon AF and so on. Therefore, first you need to see what kind of camera and mount you have.
Step 2
The second characteristic to look out for is focal length. Depending on this indicator, lenses are divided into the following types: - focal length range 8-22 mm - used for shooting landscapes, architecture, interiors (especially in cramped rooms);
- 28-80 mm - suitable for shooting events, reports;
- from 80 and above - such a focal length is necessary for shooting sports, distant objects, wildlife.
Step 3
The next indicator is aperture ratio. The larger it is, the wider the aperture is open, the more light will hit the matrix at a certain moment and the less you can set the shutter speed. Therefore, you can easily shoot even in low light conditions, such as in a theater or cafe.
Step 4
If you are going to shoot macro, then both special lenses and universal lenses with an additional macro function will suit you.
Step 5
When buying in a store, you need to check the following details: - Consider the lens in the light, there should not be any dust particles in it, because it is generally impossible to remove them from there. Each speck of dust is one spot on the resulting images;
- the zoom and aperture buttons should move smoothly, without jamming. If a grinding noise is heard during movement, then it is likely that the lens has already been dropped, in which case the purchase must be abandoned;
- After attaching the lens to the camera, check the autofocus function. In good daylight, the lens shouldn't have any focusing problems;
- the front and rear lenses must be clean from stains, streaks and other traces of use.
