Carl Zeiss Otus 55mm f1.4 APO-Distagon Camera Lens: ZE Canon

Employing a no-holds-barred design, the Canon EF-mount ZEISS Otus 55mm f/1.4 ZE is an optically refined normal-length prime characterized by its bright maximum aperture and advanced optics for high sharpness and color accuracy. The fast f/1.4 design excels in difficult lighting conditions and is also suitable for adjusting depth of field to isolate subject matter using selective focus. A Distagon optical concept is used to promote edge-to-edge sharpness and low field curvature, and, through the use of low dispersion and aspherical elements, this lens also achieves a well-corrected image quality void of aberrations, color fringing, and distortion. A floating elements system is also used, for consistent performance throughout the focusing and aperture ranges, in order to achieve even sharpness and clarity. An enhanced ZEISS T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and color fidelity when working in strong lighting conditions.

Its manual focus design is complemented by a rubberized focus ring for fine-tuned, precise control over your focus position. Additionally, Otus-series lenses also feature an equally aesthetic and durable anodized metal lens barrel surface along with engraved focusing scales and distinctive high-visibility yellow paint.

Normal-length prime lens is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides an 88mm 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 six anomalous partial dispersion elements 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.

Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 1.6' 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.
