Interested in increasing your camera kit with an extra lens or two? Not sure about lens establish and terminology linked with Slr lenses? Here is some facts that may help in production that prominent decision. Good lenses are expensive and you need to get the optimum value for your purchase.
[b]Lens[/b]Types of Lenses
There are many types of lenses on the market today, too many to cover in detail here, but here are the most tasteless types you will come over in your pursuit.
Prime or Zoom?
The first consideration is to settle either you want a zoom lens or a prime lens. A zoom lens has variable focal length so it can function as several lenses in one package. A prime lens is fixed in focal length, so it is restricted to photography that is linked to its size.
Photographers will still argue that a prime lens is always going to accomplish a better supervene than a zoom. This is an optically sound argument; however, there have been some serious advances in visual technology over the past decades and the contrast is now minimal.
Normal Lens
This lens is a prime and has a fixed focal length of 50 or 55mm. It is called a normal or appropriate lens as it provides a supervene the same as our normal viewing perspective. It is considered to be an all purpose lens and regularly the first choice if purchasing a prime.
Zoom Lens
A zoom lens covers a variable focal length, the most popular being the 35 to 70mm zoom. This lens will give the same coverage as several prime lenses over this range.
Telephoto Lens
A telephoto is any prime lens with a focal length longer than 50mm. Lenses greater than 300mm are called super telephotos; these are commonly in the 300, 500 and 1,000mm range. The greater the telephoto focal range, the greater the price tag.
Mirror Lens
A mirror lens is a telephoto lens but uses a composition of lenses and mirrors to accomplish its telephoto capability. The main contrast between conventional telephotos is its size, commonly a lot shorter. This is great for handling and a economy alternative. The downside is it has a fixed aperture and provides less resolution.
Shift Lens
This lens is also known as a perspective improvement lens, and has a rising and falling front panel that corrects perspective distortion and converging lines. These are mostly used in architectural photography.
Soft Focus Lens
These lenses are designed for separate formats, are not that tasteless and so are very expensive. The lens provides varying degrees of softness and is generally used in fashion and portrait photography.
Macro Lens
Macro lenses are commonly prime lenses and come in various focal lengths (not to be confused with the macro setting that most lenses come with). Macro lenses are for the serious macro photography as they are very expensive. Macro lenses are for ultimate close-ups at a ratio of 1:1, 2:1 or larger.
Teleconverters
These lenses contribute a cheap and easy way to expand the range of focal lengths without having to buy more lenses. These are fitted between the lens mount and the lens and growth the magnifying power of the former lens. A typical ratio is 2x and 3x converting a 50mm lens to 100mm and 150mm lens respectively.
These are a few ways to growth the capabilities of your camera that enables you to witness a greater variety of photographic subjects. Some are expensive, but others such as described here are not. There are some cheap alternatives available to help you take a supplementary step in your photography.
