The Sony E 50mm F1.8 OSS is a short telephoto APS-C prime lens for the Sony E-mount, released by Sony on August 24, 2011. [1] [2]
The lens has a mixture of high quality plastic and aluminium body. It is a comparably compact lens with a metal mount and a silent, fast autofocus. Being a small telephoto lens with a focal length equivalent of 75mm one of its purposes is portrait shots.
It features OSS (Optical Steady Shot).
Wide open the lens is rather soft but stopping down to f/5.6 yields very sharp results. That way portraits shot wide open render soft with a very nice bokeh [3] . This lens gives amateur users highest quality pictures for a budget lens in this focal length, high end users may find wide open softness and chromatic aberration, but for most of users it will surpase expectations when stopped down.
Distortion is very low and vignetting negligible, but the culprit of this lens is chromatic aberration which is very strong wide open and becomes acceptable only by stopping down towards f/5.6 [4] [5] .
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as searchlights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric", such as surveillance catadioptric sensors.
The Sony NEX-5 is a digital camera launched on 11 May 2010. It is a mirrorless interchangeable lens camera with the body size of a larger model fairly compact point-and-shoot camera with a larger sensor size (APS-C) comparable to that of some digital single-lens reflex cameras. Its major competitors in the market are the cameras based on the micro 4/3 standard created by Panasonic and Olympus, and a few low end Canon, Nikon, and even Sony α DSLRs. The NEX-5 shoots 14.2 megapixel stills and has a 7 frame/s continuous shotmode. It has the capability to shoot 1920×1080i at 60 frame/s in AVCHD or 1440×1080p at 30 frame/s in MPEG4. The NEX-5 was replaced by the 16 megapixel NEX-5N in August 2011.
