In addition to knowing what kind of mount is used on your camera, you must also be sure that your device is capable of making images that are large enough to cover its entire matrix. Due to the fact that different cameras use matrices of different sizes, manufacturers produce different lenses for working with them.
The Right Example
So, for example, Nikon DSLRs are equipped with full-format or APS-C matrices in both cases they use type F mounts, and DX-lenses are capable of receiving images large enough to cover the smaller of these two matrices. For the best Nikon lens for sports photography now you can make the right choice for the same here. For such selections, you can visit Camerakool, the best store for such high quality lenses.
At the same time, with the help of FX-lenses you can take full-size pictures, and they can also be used on DX-cameras and even on a Nikon 1 camera (with adapter). This is to ensure that lenses designed for devices with a smaller matrix are also physically smaller and lighter.
The Focal Length
If the focal length of the lens varies between two values (say, 24-80 mm.), this means that you are dealing with a lens with an adjustable focus and the ability to zoom in the specified range. On the other hand, if the focal length is determined by one number (for example, 50 mm.), This lens is a lens with a constant focal length, which means that in order to cover more or less space, you will have to come closer or move further in relation to the object, which you photograph.
The diaphragm (aperture) can be recorded in various ways however, regardless of whether it is registered as f / 2.8, F2.8 or 1: 2.8 its internal content remains the same and implies the maximum amount of light that the lens can cover. From which it follows that lenses with a larger diameter are able to perceive more light.
Since the F1.8 lens is capable of receiving more light than the F4, this means that it should be used in low light conditions without the need to use a flash, and also, thanks to it, you can get pictures with a shallower depth of field (affects how much of the image will be clear).
Some cameras with adjustable focus also have the ability to adjust the aperture, which varies depending on the focal length. So, 18-200 mm lenses with a diameter of F3.5-5.6 will have a diameter of F3.5 at 18 mm. and F5.6 if you are zooming an image up to 200 mm.
It goes without saying that you would like to purchase a lens that fits your camera in other words, you need to choose a lens with a suitable mount. Camera manufacturers typically produce lenses that are only suitable for their own devices. However, sometimes there are lenses with the ability to install on various types of cameras. The main exception here is Micro 4: 3 lenses, which can be used on Olympus and Panasonic related devices.
- Third-party manufacturers also make lenses that can be mounted on cameras of different brands.
Therefore, before purchasing a particular lens, it is important to know exactly what type of mount is used on your camera. For example, mounts on digital SLR cameras are represented by type F mounts (on Nikon devices), EF or EF-S type mounts (by Canon), and type K mounts for Pentax and Alpha (A) type mounts in the case of Sony cameras . For mirrorless cameras with interchangeable lenses, mount types include Canon EF-M, Fujifim XF, Nikon 1, Sony E, Samsung NX and Pentax Q. For cameras Micro 4: 3 from Olympus and Panasonic, as noted earlier, any lens of this type is suitable.
