Sony FE 85mm F1.8 vs Canon RF 85mm F1.2L USM
When comparing Canon RF 85mm F1.2L USM and Sony FE 85mm F1.8, which one is better?
1. Lens Mount Comparison
The lenses each feature different lens mounts — the Sony FE 85mm F1.8 features a Sony E while the Canon RF 85mm F1.2L USM 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.

Regarding lens mount: Popular lens mounts are Canon RF and EF, Micro Four Thirds and Nikon Z. Different lens mounts lets you connect different lenses to camera bodies, but some might not be compatible. This can be helped by using an adapter, like a Canon EF to RF adapter.
2. Largest Aperture Comparison
The Canon RF 85mm F1.2L USM has the largest aperture of the two lenses at 1.2 compared to the 1.8 aperture of Sony FE 85mm F1.8. This means that you get more light to your sensor using Canon RF 85mm F1.2L USM wide open, and therefore it might be a better lens in dark situations.
Winner: Canon RF 85mm F1.2L USM
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. Anamorphic Comparison
Neither Canon RF 85mm F1.2L USM or Sony FE 85mm F1.8 are anamorphic lenses.
Winner: Tied — Neither have this feature
Regarding anamorphic: Anamorphic lenses are usually used on cinema cameras and squeezes the image when its recorded, which gives the final, stretched out, image oval bokeh and a different angle of view. The most common lenses, however, are not anamorphic but spherical, which gives a spherical bokeh and is a much cheaper lens design.
4. Lens Type Comparison
Both lenses are Prime lenses, which means that you can choose both Sony FE 85mm F1.8 or Canon RF 85mm F1.2L USM 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.
5. Autofocus Comparison
Both lenses have autofocus, which means that they're both great at focusing targets while taking photographs or filming video. Just remember, most cameras do not offer good autofocus while filming video.
Winner: Tied — both have this feature
Regarding autofocus: Lenses with autofocus help you focus when shooting pictures or video. If a lens only has manual focus it means that you have to focus manually by adjusting the focus wheel on the lens. Most cinema lenses do not use autofocus and are manual focus only.
6. Macro Comparison
Neither Sony FE 85mm F1.8 or Canon RF 85mm F1.2L USM are macro lenses.
Winner: Tied — Neither have this feature
Regarding macro: Macro lenses can focus much closer to your subjects and might be suitable when photographing flowers, insects, wildlife and nature.
