Camera basics--special photographic lens

35 mm single-lens reflex camera or a camera body in pieces can be simply seen as cassettes and a long list of different additional equipment of control center. These include the lens, attached device each have their own uses. Here's the lens for 35 mm and medium format camera design, from the many existing models in the collection.

35 mm single-lens reflex camera or a camera body in pieces can be simply seen as cassettes and a long list of different additional equipment of control center.

These include the lens, attached device each have their own uses. Here's the lens for 35 mm and medium format camera design, from the many existing models in the collection.

Zoom lens and a special-purpose lens zoom lens lets you move the camera position and the change is recorded in the rate, this lens is a single machine users.

In some advanced compact camera, the zoom lens is also deemed to be a fundamental part.

Special lenses, such as ultra long zoom lens and a super wide-angle fish-eye lens, its scope is narrow.

This type of lens is expensive, but can also be rented for short. Macro lens (super close to the camera lens) for shooting close-up of small objects or parts of larger objects. This type of lens enables the camera to be taken in to the super short focus, take out the details of the full image. Buildings in shooting, moves the lens you can correct the perspective, to solve the problem of vertical convergence.

Reflective lens reflex camera lens is the lens elements and reflective together, instead of using multiple sets of camera components Pack photo taken into the lens and lens barrel of light.

These reflectors will light up and the lens barrel, refraction is equivalent to the long focal length to accommodate light control in a practical short space.

The advantages of a reflective lens reflex camera compact structure reduces long-focus lens gives people a sense of heavy.

Traditional 500 mm telephoto lens length 9.25 (235 mm), weight 35.25 ounces (1000g), while the same focal length of reflective lens only 170 ounces (485g), 3.4 (87 mm) long.

Wide angle zoom lens with a 21-35 mm wide angle zoom lens equivalent to 21 mm, 28 mm and 35 mm three lenses, and you can select any middle focal length, but with fixed focal length of lens, wide angle zoom lens maximum effective aperture smaller, weight heavier, more serious image distortion.

Telephoto zoom lens a 75-300 mm telephoto zoom lens contains approximately 6 only fixed focal length lens.

The zoom lens is very popular sports photographers and wildlife photographer's favorite. It also applies to image such as a child class of figures and moving body. Unlike the wide angle zoom, telephoto zoom lens without image distortion.

Super wide angle lens that is used for 35 mm format camera high quality lens prices very high.

With linear calibration function of ultra wide angle lens focal length range from 12 mm to 15 mm. The latter is close to the large aperture to f/8 on the design very thought.

Move the camera moving lens (also called perspective adjustment lens) to change the film Center of the screen.

Use this lens, you do not need to tilt your camera will be able to get to the top of high buildings and avoid perspective distortion. You will be able to keep the camera parallel at the same time, rising up, record no distortion of images.

Macro lens and the camera is mainly used for close-focus shot.

Macro lens focal length range of practical--in the 50-200 mm. In outdoor shooting features, the longer the focal length of the macro lens from the distant background shots out of large images. Use a shorter focal length in the macro lens, close to the part to be taken of the blocking.

Telephoto lenses telephoto lens used special design of the lens, making it in a relatively short lens barrel has a longer focal length.

Because of this name is very popular, so no matter how the structure of the camera, all of the telephoto lens is Crown this appellation. 400 mm telephoto lens, even lightweight telephoto lens, when used in a photo needs to be fixed on the bracket.
