Complementing the handling capabilities, the optical design also incorporates both an aspherical and an extra-low dispersion element, which work to suppress chromatic and spherical aberrations for increased clarity throughout the focus range. Additionally, the lens sports a dust- and moisture-resistant design to benefit working in inclement weather conditions. Standard prime macro lens is designed for full-frame Sony E-mount mirrorless cameras, and can also be used on APS-C models where it provides a 75mm equivalent focal length.True macro design affords a life-size, 1:1 magnification ratio along with a 6.3″ minimum focusing distance for working with close-up subjects. A focusing distance and magnification scale is also printed on the top of the lens to aid in more technical applications. One extra-low dispersion element is featured in the lens design and helps to reduce chromatic aberrations and color fringing for improved clarity and color neutrality.One aspherical element is incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.A focus range limiter switch allows you constrain the usable focus range between 6.3-11.8″, 11.8″-infinity, or full, and a focus hold button is also featured to manually stop the autofocus at a specified point.Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques Specifications:– Focal Length: 50mm– Maximum Aperture: f/2.8– Minimum Aperture: f/16– Lens Mount: Sony E– Format Compatibility: Full-Frame– Angle of View: 47°– Minimum Focus Distance : 16 cm– Maximum Magnification: 1x– Macro Reproduction Ratio: 1:1– Optical Design 8 Elements: in 7 Groups– Diaphragm Blades: 7– Focus Type: Autofocus– Image Stabilization: None– Filter Size: 55 mm (Front)– Dimensions 70.8 x 71 mm– Weight: 236 g
