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.

New, it sells for A$2,499.95 in Australia (Ted's Cameras); used and refurbished copies start at A$999.95. Over the last 90 days it has usually cost A$2,500 to A$2,732 new.

Worth comparing it with the Zeiss Batis 2.8/18, Sony FE 20mm F1.8 G and Sigma 20mm F2 DG DN | Contemporary.
