This video tells you what the initials or abbreviations on Nikon, Tamron and Sigma lenses actually mean for the Nikon D5200 DOWNLOAD OUR FREE GUIDE HERE http://www.d5200.org
Different manufacturers identify the different features of their lenses with different initials or abbreviations, and so we though tit wold be a good idea to go through the most common ones, so that you know what to look for if you want to buy a Nikon lens, or a generic lens for your camera.
firstly though, two very basic settings.
MM or focal length of the lens. So the larger the number, the longer the focal length, the higher the magnification and the further you can see with it. The human eye is about 30mm, So if you want to see more than that you want a higher number eg, sports lenses tend to be big, perhaps 300 – 1000mm so that they can get close to the action. They also tend to be fast…
Which brings us on to aperture. The aperture of a lens is known as the F number. Often the widest aperture is shown on the lens. So an f4 means that the widest aperture on that lens is f4 – though it will have other settings, probably going down to f22. The bigger the number, the smaller the aperture. Again, a sports lens would be f2.8 or so, so that the shutter speed can keep up with the action.
Now some of the abbreviations:
DX means that the lens is built for DX cameras like the D3000, D5000, D7000 series cameras. They tend to be smaller and lighter than FX lenses and the focal length doesn’t change. If you buy a 50mm dx lens and put it on a dx camera, the focal length will remain 50mm
IF means internal focus. This means that the front of the lens doesn’t move – so you can attach filters to the lens either clear filters to protect the lens, or polarisers or ND filters to change the light going into the lens.
ED means extra low dispersion. This is supposed to reduce the amount of chromatic abberation, which is the blue/red tinge you can sometimes see on edges when you blow pictures up.
AF-S means Autofocus. The lens has an internal motor for focusing, it might also use the initials SWM for silent wave motor. Because the D5200 doesn’t have an internal motor, if you want your lens to auto focus, it must have an internal motor
VR means vibration reduction and is designed to reduce the effects of camera shake. Very useful for low light hand held photography, and in big lenses which are hard to keep steady. Because this is automatic, you must switch this function off if you are on a tripod or it will increase blur.
There are plenty of generic lenses available for Nikon cameras. here are the abreviations for two of the bigger manufacturers, Sigma and Tamron
