The Sony FE 50mm F2.8 Macro is a full-frame macro prime lens for the Sony E-mount, announced by Sony on August 30, 2016. [1] [2]
The 35 mm format, or simply 35 mm, is the common name for the 36×24 mm film format or image sensor format used in photography. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43 mm. It has been employed in countless photographic applications including single-lens reflex (SLR) cameras, rangefinder cameras, mirrorless interchangeable-lens digital cameras, digital SLRs, point-and-shoot film cameras, and disposable film cameras.
Macro photography, is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size . By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. However, in some uses it refers to a finished photograph of a subject at greater than life size.
In film and photography, a prime lens is a fixed focal length photographic lens, typically with a maximum aperture from f2.8 to f1.2. The term can also mean the primary lens in a combination lens system. Confusion between these two meanings can occur if context doesn't make the interpretation clear. People sometimes use alternate terms—primary focal length, fixed focal length, or FFL to avoid ambiguity.

As of June 2017, the 50mm Macro lens is one of only 3 E-mount lenses manufactured by Sony that are specifically designed for macro photography, with the others being the Sony E 30mm F3.5 Macro and Sony FE 90mm F2.8 Macro G OSS lenses. Though designed for Sony's full frame E-mount cameras, this lens can be used on Sony's APS-C E-mount camera bodies, producing a field-of-view equivalent on full frame of 75mm.
The Sony E 30mm F3.5 Macro is an APS-C macro prime lens for the Sony E-mount, announced by Sony on June 8, 2011.
The Sony FE 90mm F2.8 Macro G OSS is a full-frame macro prime lens for the Sony E-mount, announced by Sony on 4 March 2015.
In cinematography, full frame refers to the use of the full film gate at maximum width and height for 35 mm film cameras. It is sometimes also referred to as silent aperture, full gate, or a number of other similar word combinations. It is the original gate size pioneered by William Dickson and Thomas Edison in 1892 and first used in the short film Blacksmithing Scene. Full frame is generally used by all 4-perf films, whether silent, standard 35, or Super 35. The introduction of Academy ratio in 1932 required that the lens mount needed to be shifted slightly horizontally to re-center the lens at the new center of frame; however, the gate size did not change as the extra negative information would be cropped out by lab processes in post-production. 4-perf Super 35 is nearly identical to the original full frame standard, although the lens mount requires vertical re-centering when common topline extraction is used. Hard mattes for all common ratios exist and either replace the film gate itself or are inserted within it. However, these are usually not used in the event that any reframing needs to be done.
