a creation Stellar choices for photographic expression Photography is creative. A photographer must make a number of critical choices that will determine the outcome. One of the most influential choices is the lens itself.

Lenses: How they capture and control light The linguistic roots of the word “photography” are the Greek words meaning “light” and “drawing.” Photography is “drawing with light,” and lenses are the brushes. After their imagination, lenses are the photographer’s primary creative tools. The way a lens captures and presents an image to the camera’s sensor determines the visual outcome more than any other factor.
Lens mount and sensor formats Alignment mark Sony A-mount and E-mount systems Electrical contacts Sony a series interchangeable-lens digital cameras are currently produced in two categories, each of which uses a different lens mount and different types of lenses. A-mount SLR (single lens reflex) type cameras have a more traditional shape and utilize moving mirrors or advanced translucent mirrors. Ultra-compact E-mount cameras don’t use reflex mirrors at all.
Focal length, angle of view and perspective Focal plane (image sensor plane) Focal length Maximum magnification ratio Focal length, or focal length range in the case of zooms, will usually be the foremost consideration when choosing a lens for a specific photograph or type of photography. The focal length of a lens determines two characteristics that are very important to photographers: magnification and angle of view.
Hoods and filters Carl Zeiss® optics Use your lens hood! The lens hoods provided with most interchangeable-lenses are not just accessories to be used occasionally. They are an important part of the lens’s optical system and should always be used in order to ensure optimum performance. There are exceptions, such as when an on-camera flash is used and the lens hood casts a shadow, but for most shooting situations the lens hood should be on the lens, not in your bag.
Making sense of MTF Choosing the right lens Those MTF (Modulation Transfer Function) graphs that often accompany lens specifications are really not as impenetrable as they look, and they can give you a good idea of how a lens will perform, so it might be worth taking a few minutes to learn what they mean. MTF describes a lens’s ability to resolve finely spaced black and white lines printed on a test target.
a lens technology The technology required to produce first-class interchangeable camera lenses is very sophisticated indeed, and that applies to every phase of the production process from design through precision parts manufacturing and assembly to stringent quality assurance testing and more. Sony brings a distinguished history of excellence in all of these areas to bear in producing the a lenses.

a lens accessories Carl Zeiss® filter High-grade Carl Zeiss filters with exclusive T* coating optimize the superb performance of your lenses, effectively reducing flare and ghosting. A thin profile also prevents vignetting. Circular PL Filter ND Filter MC Protector Circular polarizing filters improve contrast in overly bright light, and remove glare and reflections. Neutral density filers attenuate light to allow a longer exposure or larger aperture than required, without affecting colors (type: ND8).
