Tele Lens
Ways we can choose the correct target
Any owner of a camera with interchangeable lenses, are faced with the dilemma to choose the lens nice best to buy and then decide to use. However, there are no rules to follow, much depends on your personal style and what you already own. To help you decide which lens to buy and how best to use them, we offer the following services.
Normal lenses: These days, many photographers choose a zoom of 35 mm instead of a short 50 mm, but both have their virtues. If you need a fast lens, versatile range of available light f/1.4-f/2 work, nothing better than a 50mm. Positives: Generally, more compact, lighter and just a short zoom, often less expensive, usually very strong, providing a bright image display. Cons: No zoom, the need to dial to move the camera.
Short Zoom provides framing flexibility, often in a package no bigger than a 50 mm lens. A 35-70mm f/3.5-4.5 is usually smaller and less expensive, but a 28-70mm f/3.5-4.5 is useful for shooting indoors, landscapes and narrow as it goes down to 28 mm. If you making portraits, nature, sports or short range in a compact zoom 35-105mm or 35 135 mm. Normal positive capture the equivalent of two or more single focus in one hand, the package response, which provides the means of coordination is not required to pass the lenses. Normal negative Capture: open moderate (typically 3.5 to 4.5) the limits precision and low light focusing with manual focus, affect the brightness of the screen. Expand tend to be larger, heavier, more expensive than the lenses 50 mm.
Wide-angle lenses, ranging from 24 mm (on the border UltraWide) to 35 mm (length semiwide). As with normal, the choice is very compact, a single focus lens opening relatively wide (f/2-f/2.8 a few f/1.4) and aperture zoom moderate (about 3.5 to 4.5), which provide a more flexible frame. Positives and negatives of both types, see above normal lens.
Much broader approaches, such as 24-50mm 25-50mm 28-50mm, etc, are lenses normal and wide angle, which is an advantage. Some (eg, 21-35mm 18-28mm) combine UltraWide (21 mm or less) and large focal length (see UltraWide below). Many of they are not much bigger or heavier than 50 mm. Although 25-50mm or 21-35mm may not seem so impressive is the zoom (always divided by the short focal length) counts. If you need a fast wide angle lens (35mm f/1.4, for example, 28 mm f / 2 24mm f / 2) to available light shooting hand or with slow film, stick a fixed focal length.
Ultra-angle: With a focal length of 21mm in 35mm format and below that offer a wide angle coverage of 90 degrees or more. Points Positives: Ultrawide, under an extension base image, offer a great depth of field, more likely to produce sharp images when viewed at a speed slow shutter pocket. Excellent for the expansion of the tight interior spaces, making panoramas of intimate photojournalism, street photography. Negative: the apparent perspective distortion, but is useful for dramatic or comic effect, is problematic in the portrait. Avoid placing your subject near the edges of the structure or characteristics of the first plan, as the nose first.
Through telephoto lenses: Sometimes called portrait lenses, these lenses in the range of 85-135mm are ideal for portraiture, to minimize the apparent perspective distortion, and provide a convenient working distance when shooting faces closely. Many zoom TV works well in this range, but are heavier, longer and slower than a focal length. If you take a large percentage of the pictures, you should consider getting a 85mm f / 2, f/2.5 100mm f / 2 or 105 mm, even if you have a TV. Positives: They allow discreet photography of people without the effect of perspective, flattening long Teles, a type of lens combines the speed of operation, the display of images brilliant, good picture quality. Negative for zoom, see above, since only the focal length, very specialized.
Long Telephoto: Traditionally, all targets in 135mm in 35mm photography is a long distance. Today, the most popular by far is the 80-200mm zoom and 70-210mm range. Unless you need a lens that is very fast and very long (as f/2.8S excellent optics, but large, heavy and very expensive 300 mm and 400 mm used by professional sports photographers) Zoom TV options is the most flexible and economical. For many photographers, 70-210mm f/3.5-4.5 a (especially macro) is the only TV time needed. Good points: the weight of reasonable size and price range of uses, nature, sports, people, portraits, landscape. Negatives: the opening moderate and variable performance, the poor, but stopped completely. A surprisingly compact 100-300mm f/5.6 for are now available for those who need to get a little more, and there are some fine 200-500mm f/5.6 for those who need long things Teles as the largest long-distance sports plans. Long telephoto negative: greater size and weight.
