Mint Condition

The ZEISS Milvus 21mm f/2.8 ZE Lens is a wide-angle prime lens designed for Canon EF-mount cameras. Here's a detailed breakdown of its features and capabilities:

1. Optical Design and Image Quality:

   • The Milvus 21mm f/2.8 ZE employs a Distagon optical design, which ensures high sharpness and well-corrected image quality from edge to edge. This means your photos will be crisp and clear, even in the corners.
   • It features 16 lens elements arranged in 13 groups, including five low dispersion elements. These elements work together to minimize chromatic aberrations, color fringing, and distortion, resulting in accurate color reproduction and excellent contrast.
   • The lens also boasts a ZEISS T* anti-reflective coating on each surface. This coating reduces reflections, enhances contrast, and ensures faithful color rendition.

2. Aperture and Low-Light Performance:

   • With a bright f/2.8 maximum aperture, the Milvus 21mm is well-suited for low-light conditions. Whether you're shooting indoors or capturing the night sky, this lens performs admirably.
   • Astrophotographers will appreciate its wide aperture for capturing stunning starry landscapes.

3. Manual Focus and Precision:

   • The Milvus series is known for its manual focus design. While autofocus enthusiasts might miss the convenience of AF, manual focus allows for precise control over your focus point.
   • The rubberized focus ring provides a tactile feel, making it easier to fine-tune focus. Depth of field and focusing scales are also present.
   • Hard stops at both infinity and minimum focusing positions ensure consistent results.

4. Weather-Sealed Construction:

   • The lens is built to withstand the elements. It features internal seals that guard against dust and moisture.
   • Additionally, a blue sealing ring at the lens mount protects the lens-camera interface.

5. Compatibility and Focal Length:

   • The Milvus 21mm f/2.8 ZE is designed for full-frame Canon EF-mount cameras. However, it can also be used on APS-C models, where it provides an equivalent focal length of approximately 33.6mm.
   • Its ultra-wide-angle perspective makes it ideal for landscape photography, architecture, and creative compositions.

6. Weight and Filter Thread:

   • The lens weighs 735g (Nikon version) or 851g (Canon version). It feels substantial in hand, reflecting its robust build.
   • The 82mm filter thread allows you to attach filters for creative effects or protection.

In summary, the ZEISS Milvus 21mm f/2.8 ZE Lens combines optical excellence, precision engineering, and weather resistance. Whether you're an enthusiast or a professional photographer, this lens offers a unique perspective and exceptional image quality.
