TYPES OF LENSES AND ACCOMPANYING HIS CONVENIENCE
"What's going in the photo?" or
"What most noticeably the lack of kit lens?" or
"Lenses like what he wants?" and the like.
Choosing a lens in my opinion is a personal preference, one form of manifestation of personality and joy in photography. The lenses are suitable for one person is not necessarily appropriate for another. For example there is a friend who suggested using Tamron 17-50 mm lens kit as a substitute because it is more sharp. But I'm not too concerned with extra sharpness, which I really need is a telephoto lens with a good distance, so then I bought Tamron 18-200 mm a "he" is not sharp, slow, heavy, etc..
However, we may classify the lenses in several classes:
However, we may classify the lenses in several classes:
1. Standard zoom lens is a vario lens with focal length that can be changed and the maximum aperture opening changes according to the distance focus. These lenses are suitable for a variety of personal documentation purposes. 18-55 mm kit lens, 18-70 mm, 28-80 mm, and the like including these types of lenses. Because quality is potluck, many of which want a better alternative. For example: for a wider zoom range to choose from 18-105 mm, 28-135 mm, 28-200 mm, and so on. For more sharpness usually used Tamron 17-50 mm or 16-80 mm Carl Zeiss
2. Prime lenses have a fixed focal distance so that the quality and sharpness are very baik.Akan but photographers have a lot of walking to adjust the composition and proportions of the photo. Lenses of this type include 50 mm f/1.8. Alternatively, for example, 50 mm f/1.4, 50 mm f/1.2, 85 mm f/3.5, 135 mm f / 4, ff.
3. Wide lens is a lens with short focal distance in order to obtain the space of view (FOV - Field Of View) wider. This kind of lens which includes, among 10-22 mm, 11-18, etc.. Another is to the lens Pegembangan fishye, for example Samyang 8 mm.
4. Fast lens is a lens with wide aperture. The lens has an f/2.8 aperture number, f / 2, f/1.8 or smaller. The advantage, with a wide aperture, it can obtain a higher shutter speed. That's why it earned the nickname fast lens wear. Side effects of a wide aperture lens blur or bokeh is because the DoF (Depth of Field) is narrow.
5. Macro lens is a lens that has a special construction making it possible to photograph objects at close range (50 cm or less). The real macro lens has a 1:1 magnification capability, while the specification that is widely used is 100 mm f/2.8 Macro, 50 mm f/2.8 macro, and so on. However, 3rd party lens manufacturers like Sigma, Tamron, and Tokina developed vario lens with 1:4 macro capability,!: 5 or!: 7, such as the Tamron 18-200 LD Aspherical Macro In II which has a minimum object distance of 45 cm with a magnification of 1:4
6. Super telephoto lens is a lens with a focal length above 180 mm, for example 100-400 mm, 170-500 mm, and so on. The lens type is suitable for shooting sports, wildlife, birdwatching, and other objects that do not allow photographers approach the object directly. Apart from the focus distance and aperture, it should be noted also additional features on the lens that will provide facilities (with corresponding prices), including:
2. Image stabilizer is a useful feature to reduce the shock at the shooting with a low speed. This feature also has a different code, such as IS (Image Stabilizer) to the canon, VR (Vibration Reduction) in Nikon, SSS (Super Steady Shoot) at Sony, etc..
3. Coating (chemical coating optical lens) is an important factor because the response of the digital sensor to light different from the reaction on the film. Problems on the coating can cause flare, chromatic aberration (CA), ghosting, etc.. Digital lenses usually have several layers so it is marked MC (multi coating) generally perform better than the old lenses are still single coating.
4. Is an aspherical lens construction containing aspheric lens elements and serves to reduce the refraction spherical aberration caused by the shape of a convex lens.
5. Low Dispersion optical elements is minimal dispersion (spread) of light, so that the intensity of light reaching the sensor becomes higher and more details are obtained.

HISTORY OF MOVIE
Who does not love movies? It must mean most of us never watch a movie. Whether it's films from the realm of Hollywood, Bollywood, until Indonesia cheapo horror film class.

Of the 16 horses pictures WHO was running this sequentially assembled and driven Successful Produce the first motion pictures made in the world. From this emerged the idea of making a movie.

3. Producing a film is spectacular (as is done by the Hollywood film maker) of course requires a very large fee. For example, the movie Titanic to be built replica of the Titanic Itself. Titanic Itself spent 200 million dollars or if We Can rupiahkan reach 2.5 trillion dollars! But it's still not try to compare how lo ... with the cost of making filmPiratesof the Caribbean: At World's End the which reached 300 million dollars, or about almost 4 trillion dollars!
