Focal Length: 35mm
Maximum Aperture: f/1.2
Lens Mount: Canon RF mount (for full-frame mirrorless cameras)
Minimum Aperture: Typically around f/16 or f/22
Lens Construction: The lens would likely consist of multiple lens elements arranged in various groups to correct for aberrations and distortions.
Autofocus: Expect fast and accurate autofocus capabilities, possibly with Canon’s Nano USM or similar technology.
Image Stabilization: Some high-end Canon lenses include image stabilization, which helps reduce camera shake. Whether this feature is included would depend on Canon’s design choices.
Filter Thread: There would likely be a filter thread size specified for attaching filters to the lens.
Minimum Focus Distance: This would specify how close you can focus on a subject with the lens.
Maximum Magnification: This indicates the maximum size of a subject relative to its actual size that the lens can produce.
Physical Characteristics: Size, weight, and build quality of the lens would vary and would be specified by Canon.
Weather Sealing: High-end lenses often include weather sealing to protect against dust and moisture.
Compatibility: The lens would be designed for Canon’s RF mount cameras, such as the EOS R series.

Large Aperture: A maximum aperture of f/1.2 would allow for excellent low-light performance and shallow depth of field, making it suitable for various shooting situations, including portrait, street, and low-light photography.

High-Quality Optics: Canon would likely design the lens with high-quality optics, possibly including aspherical and UD elements to minimize aberrations and distortions and deliver sharp, high-resolution images.

Advanced Autofocus System: Expect fast, accurate, and silent autofocus performance, possibly utilizing Canon’s Nano USM or similar technology for both still and video shooting.

Image Stabilization: Canon might incorporate image stabilization (IS) into the lens to help reduce camera shake, especially useful when shooting in low light or with slower shutter speeds.

Weather Sealing: Professional-grade lenses often feature weather-sealed construction to protect against dust and moisture, allowing photographers to shoot in challenging environmental conditions.

Customizable Control Ring: Canon’s RF lenses typically include a customizable control ring that allows photographers to adjust various settings such as aperture, ISO, or exposure compensation conveniently.

Compact and Lightweight Design: While a fast aperture lens like an f/1.2 prime may be larger and heavier than slower lenses, Canon would likely strive for a balance between optical performance and portability.

Fluorine Coating: Canon often applies a fluorine coating to the front and rear lens elements to repel dust, water, and smudges, making it easier to clean and maintain the lens.

Compatibility with Canon RF Mount Cameras: The lens would be specifically designed for Canon’s RF mount cameras, ensuring seamless compatibility and optimal performance with Canon’s latest mirrorless cameras like the EOS R series.
