Zeiss Loxia Sonnar 2.4/85 T* vs Canon RF 85mm F2 MACRO IS STM
When comparing Canon RF 85mm F2 MACRO IS STM and Zeiss Loxia Sonnar 2.4/85 T*, which one is better?
1. Lens Mount Comparison
The lenses each feature different lens mounts — the Zeiss Loxia Sonnar 2.4/85 T* features a Sony E while the Canon RF 85mm F2 MACRO IS STM features a Canon RF — and because of this the preference varies. If you have a compatible camera, then of course that lens will be a better choice for you.

2. Largest Aperture Comparison
The Canon RF 85mm F2 MACRO IS STM has the largest aperture of the two lenses at 2 compared to the 2.4 aperture of Zeiss Loxia Sonnar 2.4/85 T*. This means that you get more light to your sensor using Canon RF 85mm F2 MACRO IS STM wide open, and therefore it might be a better lens in dark situations.
Winner: Canon RF 85mm F2 MACRO IS STM
Regarding largest aperture: A lower aperture number means that the widest aperture on the lens is larger. This means that more light will hit the sensor and also that the depth of field will be shallower, better separating your subject from the background.
3. Lens Type Comparison
Both lenses are Prime lenses, which means that you can choose both Zeiss Loxia Sonnar 2.4/85 T* or Canon RF 85mm F2 MACRO IS STM if you're looking for that type of lens.
Winner: Tied
Regarding type: There are two types of lenses; zoom lenses and prime lenses. Prime lenses have a fixed focal length and cannot be zoomed, while zoom lenses have a focal length range and can be zoomed in to get closer to the subject. Prime lenses are usually lighter, cheaper and let in more light. Zoom lenses are more versatile but are more expensive since they require a more advanced lens design.
