Camera lenses for both digital and film cameras can be categorized into three types: standard camera lenses, wide-angle camera lenses, and telephoto camera lenses. Camera lenses are subject to many kinds of distortion, all of which are more difficult to reduce in a zoom lens design. Camera lenses may seem like a ho hum topic, much like the nonrotating wheel in prehistoric times, but therecent perfection of several technologies has made lenses an exciting part of the camera again. Camera lenses should be kept clean, but it is a mistake to clean them too often. Tamron is a leading manufacturer of digital camera lenses for photographic, industrial, laboratory, video, digital and scientific applications. When it comes to shopping for a photo lens, eBay is a photographer's dream, featuring an ongoing inventory of digital camera lenses and film camera lenses. Standard camera lenses Think of a standard camera lens as replicating a perspective similar to the human eye. Wide-angle camera lenses A wide-angle camera lens gives you a wide angle of view, offering a larger, sweeping perspective and better depth of field and reproduction than a standard camera lens. Telephoto camera lenses As opposed to the wide-angle camera lens, the telephoto camera lens is a narrow angle lens. Macro camera lenses .If you’re interested in extreme close-up photography, consider a macro camera lens that allows for extremely sharp focusing at short distances. Generally macro camera lenses are used for science and nature photography, but can also be used for taking pictures of collectibles, such as coins and stamps. A fish-eye camera lens is an extremely wide-angle lens. Standard camera lenses typically have a 50mm to 55mm focal length. Telephoto lens: Telephoto camera lenses have a 80mm to 500mm focal length. Some camera lenses offer both types of focus functionality. Therefore, it’s becoming easier to use film camera lenses on digital cameras. Film lens formatsFilm cameras and film camera lenses come in three formats: 35mm SLR lenses, medium-format lenses, and large-format lenses.
The first step that you want to do is, you want to make sure that there are no abrasive particles on the lens. If you had some abrasive particle on there, and you wiped it , it would create a really bad scratch on the lens. Once you got all of the abrasive particles off the lens, then you could go and start to clean your lens. First get a fresh piece of lens cleaning cloth. The most important thing is don’t over clean your lens. Every time that you clean you run a risk of possibly putting a scratch on your lens, and you want to avoid that at all cost. A good investment will be to install an UV filter onto your lens. It is just a glass filter that fits in front of your lens and that way it protects your lens, so that if you got a scratch, all that you would scratch is your $15 or $30 uv filter, versus your very expensive camera lens.
