DSLR Lenses and their abbreviations

For those of you who know what these abbreviations, I have compiled a list of terms used for what it is and, of course, what really does it for you or avoid.

Abbreviations General.

Before getting to the nitty gritty of why they are all different, we see the similarities. There are three common terms to describe her slow and easy to understand and apply only the most creative and performanceFunctions.

Focal length: - The scope of the scene captured Example 16 - A 35mm lens, which covers an area of 16mm (relatively wide) to 35 mm zoom ..

Maximum aperture: - The maximum rate at which the lens can let in light. eg f3.5 or 2.8 - 5.6

If your goal is just a number, so that as open as possible.

If the lens has two numbers, then as open as possible depending on the focal lengththe lens is in focus.

The lower the number the larger the aperture and the fastest in the light. (See my forthcoming article on the law of reciprocity)

AF / MF switching between autofocus and manual focus

Canon Lens Abbreviations

Conditions for Canon lenses, describe

Canon produces an extremely wide range of lenses for its EOS cameras. The fields produced by Sigma, Tamron and Tokina Canon owners are married to awide range of Canon lenses Fit SLR. The abbreviations used by Canon, as shown below.

EF: Electronic Focus. Lens Mount fits all Canon EOS SLR range.

USM ultrasonic motor for autofocus. Two species. Micro USM as a direct replacement for the old engines and ring systems of FD 'USM "with manual control.

OD: optical diffraction. Establish a technology, Canon lenses in the short overall length.

TS-E tilt-shift lens for perspective correction for photography, as a rule change in the architectural work of converging lines and depth of field. Similar to "Sinar"> Camera.

The lenses: Canon professional with better optical quality and features not specifically. Usually white. All L-series lenses have a red ring on the outside ..

MP-E Macro optoelectronics. Macro lenses for an electronic control panel designed to work.

IS: Image Stabilization developed a system to reduce vibration of the hand. The Nikon version is called VR (Vibration Reduction) and a Sigma OS (OpticalStabilization).
