The Zeiss Loxia E 50mm f/2 Planar for Sony E is a high-quality manual-focus lens designed for full-frame E-mount cameras like the Sony a7 III, a7R III, and a9. Key features include:
Classic Design. Based on the great Zeiss ZM 50mm f/2 Planar for Leica, the Zeiss Loxia E 50mm f/2 Biogon is manual-focus, manual-aperture lens with electronic contacts for transmitting EXIF data and focus confirmation with Sony E-mount cameras. While it’s optimized for full-frame cameras, the Loxia line of lenses is fully compatible with APS-C Sony E-mount cameras with a 1.5x crop factor.
Standard Prime. When used on a full-frame camera, you have yourself a “nifty fifty” that’s long been popular for just about every type of photography. With an APS-C sensor camera, you’ll have a normal/short tele lens with a focal length equivalent to 75mm.
Fast Aperture. The f/2 aperture enables decent low-light shooting speed and great background blur for controlling depth of field. The manual aperture ring offers 1/2-stop clicks throughout the f/2-22 range, as well as the ability to mechanically switch to clickless operation.
Manual Focus. The knurled metal focus ring rotates 180º, providing smooth, weighted operation. Engraved depth-of-field and distance-scale markings ensure easy visibility, and the lens’s built-in electronics enable both focus confirmation and automatic viewfinder magnification.
Advanced Optics. The symmetrical Biogon design features four groups/six elements to minimize chromatic aberrations and distortion without the need for additional specialized elements. Carl Zeiss T* anti-reflective coating eliminates lens flare and ghosting while providing the famous high micro-contrast Zeiss look.
High-Quality Build. The all-metal barrel provides gives the Loxia 50mm a solid feel with a weather-resistant gasket at the lens mount to protect against the elements.
