Using the Correct Lens for the Perfect Photograph

The SWISS Army Knife, a fantastic tool that is great for a number of jobs

Although I wouldn't want tile a kitchen floor using one. Some tasks require more specialized tools. Which is the way it is with lenses.

Macro lenses are employed for small subjects such as insects at extremely close ranges. The lenses that are included with the typical DSLR cameras are proficient at a multiplicity of shots, although not outstanding at a single one of them. If you desire to take extraordinary close-ups,, portraits, landscapes or whatever, a quick road to triumph is to get a specialized lens. Which lens you get depends upon the types of photographs you intend to shoot. Shorter lenses include a wider panorama to subjects like interiors. Longer lenses lead to bringing distant objects closer in such as, wildlife. Generally, the more light the lens allows in, the better the lens it is. The additional light makes it viable to photograph in poor-light condition, such as shooting around a night time campfire. The low-light capability of a lens can be determined by the "f" number. The smaller this number, the more volume of light it absorbs, and the faster typically it is, and the more it typically costs. Therefore an f/1.8 lens acquires additional light over an f/2.8 lens. A lens is actually a collection of many lenses. Manufacturers save money many times by including some plastic lenses, although lenses made of all-glass are substantially better.

The lens's weight is a clue; the more it weighs, usually the better the lens is. However price alone is no assurance of good quality, some lenses of comparable size may have wide price differences., sometime into thousands of dollars. Most often, the more costly lenses are quicker and have higher quality optics. When getting a wide-angle lens or a telephoto, the image sensor of the digital camera creates a complication. Before digital when people used 35mm film, every cameras produced the same magnification using a lens with a particular length. a 100mm lens was a 100mm lens. However that magnification ratio was based upon the association between the film (or image sensor) size and the lens length.

Most image sensors on DSLR’s are not as large as 35mm, so, the effect is that the lenses seem like they are much longer and magnify much more than the 35mm equivalent. This means that wide-angle lenses must to be even wider to achieve the same effect as on film. Telephoto lenses will function like they are actually longer. To compare apples-to-apples a conversion number tells Crop Factor Digital camera users what an equivalent lens SLR 35mm film camera would be. For example, if the conversion factor is 1.5, a 200mm telephoto lens will act like a 300mm lens on a 35mm film camera. Here are some descriptions of various lenses and the sort of images they shoot.

FISHEYE. Radical wide-angle lenses, several fisheyes capture a 180-degree scene. This distorts the image in the frame although is great for acquiring small, cluttered indoor spaces or vast outdoor expanses. They are often used for humorous portraits.

Fisheyes are most often used for out of the ordinary photos
and to acquire tight indoor spaces or wide outdoor expanses.

 

MACRO. Macro lenses allow photographers to acquire tiny subjects at extremely close ranges. They are often employed for close-up photography such as photographing insects or flowers.

TELEPHOTO. The telephoto lens pulls distant objects closer. This is the lens used for bird-watching along with field sports and parades

WIDE-ANGLE. Also labeled "a story-telling lens." Not as wide as fisheyes, they still take in a lot of real estate and due to their short focal lengths, they can leave both the background and foreground in focus. Great for travel pictures.

PRIME. Lenses with no zoom function. Because they contain less moving parts and elements, these fast prime lenses may be purchased for much less expense than comparable speed zoom lenses. The speed benefit is twofold. The lenses perform better in poor light and shooting images where your subject is in clear focus while everything else looks artistically blurred is easier. These lenses are available all the way from wide-angle through telephoto, however 50mm the most prevalent length, which is a great length for portraits using a DSLR. camera which has the most typical image sensor size.
