Loxia 2.8/21 overview
The Zeiss Loxia 2.8/21 is a 21mm f/2.8 prime for full-frame cameras on Sony E-mount, announced by Zeiss in October 2015. 39 cameras we track take it without an adapter. It is discontinued, so new stock may be limited.
Going by its spec sheet, it suits landscapes and interiors. It is a weaker pick for fast-moving subjects and close-ups.
No store we track in Europe lists it today. It is listed in the United States, the United Kingdom and Australia. It launched at €1,499.
Worth comparing it with the Zeiss Batis 2.8/18, Sony FE 20mm F1.8 G and Sigma 20mm F2 DG DN | Contemporary.
