Camera Lens and How to Take Care of Them
The camera lens is one of the most important parts of a camera, the image quality will ultimately depend on the lens quality. There is no such thing as the perfect camera lens because each lens has its advantages and disadvantages. Standard lens has those with a length of 50mm, the most used format. All SLR cameras come with interchangeable lens, perfect to replace this lens for the other for that particular photo.
When shopping for more lenses for your camera keep an eye on some technical definitions. The aperture is the maximum amount of light that the lens allow to pass through the sensor and the smaller this number is, the more light will pass through the sensor the better the image will be. The perfect number is one but that is not possible yet. The best around is 1.2 but that’s not necessary for the average user, above 2 and even three is good enough for a good picture.
The next feature to consider is the focal length, if you use a telephoto lens you will be prone to take blurred images because focusing on distant objects increases the movement sensitivity. The wide angle is perfect to photograph nature because you can capture more field than with the telephoto lens, each lens has its own advantage and no lens is perfect for all situations.
There is another characteristic you must pay attention to which is the zoom. A lens with no zoom is not able to approximate distant objects to you so a zoom lens is the ideal pick here. A zoom of 3x is more than enough for the home user. Fixed lens come with the advantage of possessing more image brightness than zoom lens.
Camera lens will be as good as the protection you give to them and an SLR camera lens is such an investment. It will be scratched without proper care and once scratched there is no way to fix it, you will need to buy a new one to have high quality pictures again. You can fully protect it by buying a camera hood for each lens you have. They are so cheap it makes no sense not to have one for each and does wonders to help protect the lens. This will protect the lens if the camera falls down absorbing some shock and to take damage in case something sharp collides with the lenses. Another way is to purchase a filter, the best protection move you can make for your camera lens.
The filter is placed between the lens and the rest of the world so you guessed it, the filter will protect the lens from UV rays, from scratches and pretty much anything else. Finally use the camera lens cap, some people have it but do not use it, which is so wrong. The cap will ensure that nothing will be able to damage the lens, except a big fall.
