It breaks down the different types of lenses you can get, the variations you can find within that, along with suggestions for when you would use each one. Standard lenses have a mid-range focal length, somewhere around 50mm - but really anything between 40mm and 60mm. The most common focal length is the one that falls slap bang in the middle of that - the 50mm.
DSLR Lenses – An Introduction
Shorter focal length lenses provide a wider field of view but offer less magnification. Conversely, longer focal lengths provide a shorter field of view but provide greater magnification. The focal length of a lens is usually displayed on the lens barrel, along with the size of the adaptor ring. The lower the maximum aperture value will indicate the quality of the lens in terms of brightness. High quality zoom lenses deliver a constant f-stop throughout the focal range i. A lens with a low f-number wide maximum aperture , is a better quality lens and allows you to do more with it.
In addition, these bright lenses will enable you to achieve a very shallow depth of field. The standard lens has a fixed focal length 50mm, 85mm, mm , and reproduces fairly accurately what the human eye sees — in terms of perspective and angle of view. For a 35mm film camera or a full-frame DSLR, the 50mm lens is considered standard. At higher focal lengths 85mm or mm you have an ideal lens for portraiture because when coupled with a wide aperture they thoroughly soften any background detail, thus making it less likely to distract from the main subject.
A wide-angle has a shorter focal length 10 thru 42mm when compared to a standard lens. This enables you to capture a comparatively wider angle of view. A wide-angle lens is a natural choice for capturing outdoor landscapes and group portraits. In fact, wide angle can be the only way to capture the complete setting without omitting any important elements in the image.
Telephoto lenses mm — mm can provide you with a narrow field of view. These long lenses enable you to compress a distance and compress the sense of depth, as well and pick out specific objects from far off. They have a strong resolving power and an inherent shallow DOF, where the slightest lateral moment can take a subject out of view.
Telephoto lenses are great for wildlife, portrait, sports, and documentary types of photography. Some can range between a wide-angle and a telephoto i. The trade-off with zoom lenses is the aperture. Because of the number of elements required in constructing these lenses, they have a limited ability to open up and allow in light.
A fisheye lens is a specialized, wide-angle lens that provides extremely wide images by changing straight lines into curves. They range in focal lengths of between mm. These lenses obtain razor-sharp focus for subjects within the macro focus distance, but lose their ability for sharp focus at other distances.
These lenses enable the photographer to obtain life-size or larger images of subjects like wasps, butterflies, and flowers.
The tilt-shift lens also enables you to selectively focus an image; where only specific portions of the image are in focus and out of focus within the same plane. These lenses contain small gyro stabilizer sensors and servo-actuated lens elements, which purportedly correct for camera shake that occurs with longer focal length lens or in low-light conditions when you need to have slower shutter speeds to achieve an effective EV.
It is claimed that these lenses enable the user to shoot handheld at 2 to 4 stop slower shutter speeds exposure 4 to 16 times longer than the minimum required for a sharp image. There are many possible lens choices, and all will give you a different and distinct image. Part of the creativity of the photographer is in selecting the right lens to capture the vision of the world the way she or he sees it, or wants to present it.

There are many things that determine the quality of your photography, and one of the most important is the lenses you use. A good camera lens will capture sharp photos with plenty of detail and contrast, while a poor one can leave your images looking dull and blurry. When shopping for lenses, it's important to consider the types of subject you intend to shoot, the likely lighting conditions, and of course your budget.

Shorter focal length lenses provide a wider field of view but offer less magnification. Conversely, longer focal lengths provide a shorter field of view but provide greater magnification. The focal length of a lens is usually displayed on the lens barrel, along with the size of the adaptor ring. The lower the maximum aperture value will indicate the quality of the lens in terms of brightness. High quality zoom lenses deliver a constant f-stop throughout the focal range i.
Entering the world of photography can be a minefield when it comes to the different types of lenses on the market. Even the experienced photographer will be hard-pressed to explain the exact differences and function of each particular lens, but knowing more about the functionality, focal lengths and uses of a lens can help you to employ it in the right situation. And knowing when to use the correct lens, is just one step towards becoming a much better photographer. In this article, we take a look at the different types of camera lenses and when they should be used.

Standard Lenses — this is a term that seems to be disappearing a little from terminology. Traditionally on film cameras it was used to describe lenses in the 50mm range because this is what usually came with the camera. It is generally an entry level quality zoom lens.

Быть может, вы могли бы… - Право же, без фамилии я ничего не могу поделать. - И все-таки, - прервал ее Беккер. Ему в голову пришла другая мысль. - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина. - Тогда вы наверняка ее видели.

Плутоний впервые был открыт… - Число, - напомнил Джабба. - Нам нужно число. Сьюзан еще раз перечитала послание Танкадо.
Не может быть, что служба уже закончилась. Это невозможно. Да мы только вошли. Но, увидев прислужника в конце ряда и два людских потока, движущихся по центральному проходу к алтарю, Беккер понял, что происходит.
На сей раз голос его прозвучал с несвойственным ему спокойствием: - Директор, если мы введем неверный ключ… - Верно, - прервала его Сьюзан. - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов. - Как у нас со временем, Джабба? - спросил Фонтейн. Джабба посмотрел на ВР.
Мертв. Но это значит… значит… что мы не можем… - Это значит, что нужен другой план действий. - Фонтейн, как обычно, говорил спокойно и деловито.
Отключение ТРАНСТЕКСТА было логичным шагом в случае возникновения чрезвычайной ситуации, а ведь тот был уверен, что в машину проник вирус. К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности. После таких экстренных действий на главном коммутаторе раздавался сигнал общей тревоги. Проверку шифровалки службой безопасности Хейл допустить не .
Мидж… - Джабба попробовал извиниться. - Позволь мне объяснить.
