Everybody knows about the basic type of cameras because you keep hearing about them from everywhere, but not many people know about camera lenses, not even the basics.

Just like a camera, lenses are also very important to know about and being able to differentiate between them is a job for a well-trained eye. Lenses are the most essential part (read about other essential camera accessories athttps://www.facebook.com/notes/world-photographers-club/know-your-gear-wpc/1844792799123705 ) of a camera if you want to conduct amazing photography or videography even.
There are 7 not so famously known lenses that make that amazing photographs that we see on the internet daily, happen. Let’s discuss those through:-
1. Kit Lens – This is not a specific type of lens, rather it refers to the lens that comes with a DSLR camera body as part of the deal. It is possible to buy the camera without a lens, and this is how most high-end DSLRs are sold. Retailers sometimes make up their own kits of DSLR body and lenses, so there can be a variety of kit lenses for the same DSLR.
2. Fast Lens – These are lenses with a large maximum opening, or aperture, letting in more light. Typically the apertures range from f2.8 and lower. Lower f numbers mean larger apertures and more light coming in through the lens. Fast lenses are an advantage even for photographers using smaller apertures, or larger f numbers. All composing, metering, and focusing on modern SLR and DSLR cameras and lenses is done with the lens at maximum aperture. When the shutter is released the lens aperture changes to the setting for that image.
3. Zoom Lens – This is a lens with variable focal length. The range of focal length is indicted in the name of the lens. The example photos were taken with a Sigma 18-125 mm zoom lens. So it goes from a wide angle at 18 mm focal length to telephoto at 125 mm focal length. One characteristic of many zooms is that as the focal length changes the maximum aperture changes. For a true zoom lens the focus should not change as the photographer zooms, or changes the working focal length of the lens.
4. Prime Lens – A prime lens has no zoom – it is one focal length, and one only. Because the lens is manufactured precisely to provide this one length and doesn’t have the moving pieces and mechanisms required to zoom, they can be tack sharp. Again, because of the relative simplicity of their build, they can have larger apertures (the size of the opening in the lens), and therefore are much more useful for indoor and low-light photography. If crisp and clear images are more important to you than convenience, these are the lenses you want to look at.
5. Mirror Lens – These unusual lenses use a combination of lenses and curved mirrors to achieve a long focal length in a compact lens. One of the drawbacks is that they have a fixed aperture, or out of focus shapes, are unusual. With f8 as a typical maximum aperture, they are a bit slow compared to current telephoto lenses where a maximum aperture of f4 is common.
6. Macro Lens – The macro lens has an intense level of magnification, capable of picking out the tiniest details and enhancing them larger than we can see with our own eyes. These lenses are able to focus closer to an object than normal lenses, offering a 1:1 ratio. They are used for still-life photography of small objects.
7. Shift Lens – This is a specialist type of lens primarily used for architecture to solve the problem of tall buildings converging at the top of a photo. This happens when photographers angle their cameras upwards to include the top of buildings in their photos. A shift lens allows photographers to hold the camera body vertical and move the lens to include the top of the building.
