ZEISS 21mm f/2.8 overview

  • 1Description

Combining an expansive field of view with a compact form factor, the Loxia 21mm f/2.8 from ZEISS is a sleek wide-angle prime, designed for full-frame Sony E-mount mirrorless cameras. Based on the Distagon optical concept, this lens uses four anomalous partial dispersion elements and one aspherical element to provide a marked reduction in chromatic and spherical aberrations for improved color rendering, sharpness, and clarity. For minimizing flare and ghosting, an enhanced ZEISS T* anti-reflective coating has also been applied to benefit working in difficult lighting conditions.

Loxia-series lenses are distinguished by their manual focus operation along with a manual aperture ring that can be de-clicked for silent operation; making them especially suitable for filmmaking applications. Loxia lenses are also characterized by their compact form factor and all-metal lens barrel, which incorporates engraved focusing and depth of field scales, for fine-tuned control. Additionally, the lens body sports a dust- and moisture-sealed design to permit its use in trying environments.

Wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it provides a 31.5mm equivalent focal length
Bright f/2.8 maximum aperture suits working in available-light conditions and is also well-suited for astrophotography use.
Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
Four anomalous partial dispersion elements are used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
One aspherical element controls distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering.
ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
Manual focus design is benefitted by focusing and depth of field scales along with a 90° focus ring rotational angle and hard stops at both infinity and minimum focusing positions.
Manual aperture ring has clicked indicators throughout aperture range. Using the included De-Click Tool, this ring can be mechanically 'de-clicked' for smooth, silent rotation throughout the aperture range; making it ideal for video applications.
Weather-resistant construction includes internal seals to guard against dust and moisture as well as a blue sealing ring at the lens mount to protect the lens-camera interface.
The lens mount is fitted with an electronic interface that conveys all lens Exif data to the camera and can also be configured to automatically activate the camera's focusing magnification function when turning the focus ring.

    ZEISS 21mm f/2.8 reviews

    Loxia 21mm f/2.8 Lens for Sony E Mount is rated 4.9 out of 5 by 40.
    Rated 5 out of 5 by from A splurge, and absolutely worth it This is an expensive lens, by my standards, but the first I've found that takes every advantage of the 42-megapixel sensor in my Sony A7rII. It is crisp from corner to corner, even wide open, and the color and contrast are a revelation. I used my old Canon FD lenses (20mm and 17mm) for a long time, and they were great, but this lens is in a different class altogether. It's manual, but I see that as an asset, especially since (particularly with wide-angles) autofocus doesn't regularly focus where I want it to. AND, this lens is sufficiently automated to engage the focus-magnification feature in my camera, and leave behind EXIF data, too! This is one heck of a lens.

    Rated 5 out of 5 by from A keeper for wide angle shooters The Good: Sharp images, very little distortion, nice colors, fast, compact and fun to use (I am an amateur photographer) The Bad: As other reviewers stated, a little tricky to connect to camera housing due to weather sealing and limited grip area. Very little real estate between aperture ring and focus ring, hence caution is advised when changing aperture. Last, but not least: Rather expensive lens! The Ugly: No complaints here. Summary: For amateur shooters who are really into wide angle photography, I'd say it is worth the money. If you shoot W.A. only occasionally, you might be content with a 24 mm legacy lens.

    Rated 5 out of 5 by from Oh my. I've heard so many good things about the Loxia 21 compared to the DSLR version, the Distagon 21/2.8, that I've been using on my A7RII. I expected the Loxia to be better, but...what a difference. Center sharpness is similar, although I'd say with a slight edge to the Loxia. But the ends on Loxia are also terrific, even into the farthest tips of the corners. Simply amazing, and when you consider the reduced bulk and weight, it's a no brainer. I should have ordered it sooner. Hoping for a 28mm Loxia sometime soon...

    Rated 5 out of 5 by from Worth the hype The most gorgeous wide angle lens I have ever used. The focus ring is insanely smooth, the build is incredible, and the pictures have a sharpness and a look that you will fall in love with. The best of the Loxia line and one of the best wide lenses you will ever use. Extra points for the fantastic hood and being able to de-click the aperture for video. A fantastic lens for photography and video. It does vignette wide open, but that's to be expected and is gone once you stop down.

    Rated 5 out of 5 by from Zeiss, please expand the Loxia line! I was initially torn between the Batis 18 and the Loxia 21. I had a lot of trepidation contemplating the purchase of a manual focus lens, especially to pair with such an advanced camera system such as the Sony A7Rii. After renting both, I quickly decided that it was a no-brainer, and the Loxia 21 was the superior lens of the two, for my purposes in landscape photography. Took the Loxia 21 with me on a 3 week trip to France, and it hardly came off my camera. I loved this lens so much, that when I return from my trip, I immediately purchased the Loxia 35. I will most likely end up purchasing the Loxia 50 as well as any other Loxia lens that Zeiss ends up creating. As many reviews have stated, the build quality is second to none, and the form factor is a PERFECT match for the A7 line. The image quality is stunning. If you own an A7 series camera and wide angle/landscape photography is your thing, this lens is a must own.

    Rated 5 out of 5 by from excellent optic, aperture design lacking Very sharp, better than the Zeiss 25/2. Which wasn't as sharp as my adapted Canon 16-35 f/4. For precise focus On the A7r2, I focus wide open in A mode w/magnified view & stop down to expose. Not ideal! I would have preferred auto aperture. Off of the tripod I zone focus using the distance scale. Again auto aperture & magnified view would have been better. I don't care for focus peaking on a wide angle lens. The aperture ring is to flush with lens body, difficult to use. I added two layers of 3/16 wide Gorilla(thick) tape to the aperture ring. It raises it up enough to make aperture changes easier. Not exactly in keeping with the jewel like quality of the lens, but it works. I've used it for years on other camera's. Heat's not a problem in the NW, in the SW maybe less so.

    Rated 4 out of 5 by from Superb Sharp! I sold my Sony Zeiss 16-35 2.8 to purchase this lens and I made the right decision. I would have preferred auto focus but can live without it. I use this lens for architecture and landscape. The best image quality achieved at f8.

    Rated 5 out of 5 by from Fantastic One of the most enjoyable lenses you can use on an A7 series and probably one of my favorite lenses I have ever used. Just a fantastic rendering and great sharpness. It has to be one the best wide angle lenses I have had the pleasure to use. Expensive, but in this case you really get what you pay for. Good luck finding it in stock, but hopefully it will be more available.
