Capture 4K images on a full-frame sensor with this SLR Magic MicroPrime Cine Lens Kit put together by B&H. The set includes 25, 35, 50, and 75mm MicroPrime Cine lenses that share characteristics such as a similar size and weight, consistent gear positions, full-frame sensor support, a 13-blade iris, internal focus design, an 85mm front diameter, and an 82mm front filter thread which make changing focal lengths a breeze while shooting. All four lenses feature a Sony E-mount.

The 21mm Ultra-Wide Conversion Lens for FE 28mm f/2 Lens from Sony broadens the angle-of-view of the 28mm f/2 lens to 92º for an ultra wide focal length equivalence of 21mm when used with full-frame cameras. As this converter lens is uniquely compatible with the FE 28mm f/2 lens, it transmits EXIF data through the host lens to the camera. The optical design of the converter lens is comprised of 4 elements in 4 groups and when on the 28mm lens, it provides a maximum aperture of f/2.8 and a minimum manual focus distance of 7.9″. When the lens is used with an APS-C E-Mount camera, the converter lens provides a 68° angle of view and a 31.5mm focal length equivalent. It is a compact addition to the 28mm lens with a bayonet mount and features a built-in petal-type lens hood.
