Bright-eyed and wide-angled, the Canon EF-mount ZEISS Otus 28mm f/1.4 ZE is an optically-refined prime poised to deliver a high degree of resolution and clarity in nearly any shooting condition. Featuring an apochromatic design, and utilizing the Distagon concept to reduce distortion, this lens uses a series of eight anomalous partial dispersion glass elements and two aspherical elements to virtually eliminate chromatic and spherical aberrations throughout the aperture range. A floating elements system is also used for consistent performance throughout the focusing range and a ZEISS T* anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity. Equaling the optical prowess of a Strigidae-inspired lens, the Otus 28mm f/1.4 is also characterized by a robust physical design for intuitive, exacting handling.

The wide-angle focal length pairs with the bright f/1.4 maximum aperture to suit working in broad variety of lighting conditions and is well-suited to a range of applications, including landscape, architecture, and interior photography. Accentuating the range of control, this manual focus lens is complemented by haptic design elements, including a rubberized focus ring and an all-metal lens barrel with high-visibility yellow scale markings.

Wide-angle prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 44.8mm equivalent focal length.

Impressively bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.

Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.

Apochromatic optical design utilizes eight anomalous partial dispersion elements to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.

Two aspherical elements control 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.

Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 11.8" to infinity.

Manual focus design is benefitted by focusing and depth of field scales, which are filled with a high-visibility yellow paint, along with hard stops at both infinity and minimum focusing positions.

All-metal lens barrel has a frosted, anodized surface along with a rubberized focusing ring for both durability and improved tactile control.

Q: 1. Can you manually change the iris on these lenses?

A: No, as with most lenses compatible with the EF mount system, the aperture on the ZEISS Otus ZE lenses is controlled electronically by the camera body.

Q: 2. Sony?

A: Yes. the following unit will mount but an adapter must be set in its place. Please review the following items. https://bhpho.to/3vUanM0

Q: 3. Can this lens work on a Nikon FM3A film camera? And how about Leica M cameras?

A: Yes, the ZEISS Otus 14/85 will work on this FM3A camera. For a complete list of compatible cameras, visit our site at: https://www.zeiss.com/camera-lenses/int/photography/content/camera-mounts.html. With regards to compatibility with M mount cameras, yes it can be used with any 3rd party F-mount to m-mount adapter.

Q: 4. is it sealed against dust and moisture?

A: I'm sorry - I really don't know. Sorry!

Q: 5. Is there any way to use a Zeiss Otus lens on an Arri Alex Plus, that allows the F-Stop to be changed?

A: The ZEISS Otus Lens is available in EF or F mount. The first determination is whether this camera model has an optional mount system to accept these still camera mounts. Second, if an EF mount option is available, it must be an 'active' mount in order to engage the electronic aperture in the lens.

Q: 6. Will I have manual aperture control when using this lens with the Black Magic Pocket Cinema Camera (using a dumb Photodiox Nikon F to MFT adapter)?

A: yes, you can. Agree, with previous answers. It has F-stop ring. It is manual.

Q: 7. Is there an adapter to the full frame NEX a7 which would transmit the focus confirmation light?

A: I don't know about the mount for the model u have though I believe there is one for the nex 5. On my d800 the 50 mm zeiss can produce soectacular pictures tho it takes time to get used to manual focus. I hope This helps. Robert

Q: 8. Two lens gears or three?

A: The ZEISS Otus ZE 3-Lens Bundle for Canon EF includes three lens gears. You get one ZEISS Lens Gear (Medium) abd two ZEISS Lens Gear (Large).

Q: 9. Dows this lens work with apsc sensors?

A: You will be able to use this APS-C sensors as long as it is a Nikon F mount camera.

Q: 10. Would you please explain to me.why zeiss do not have 85mm circular polarize{CP} ?

A: Could be because Zeiss doesn't make a lens that takes an 85mm filter.
