Atlas Orion 21mm T2 2x vs Canon RF 85mm F2 MACRO IS STM
Atlas Orion 21mm T2 2x vs Canon RF 85mm F2 MACRO IS STM
When comparing Canon RF 85mm F2 MACRO IS STM and Atlas Orion 21mm T2 2x, which one is better?
1. Lens Mount Comparison
The lenses each feature different lens mounts — the Atlas Orion 21mm T2 2x features a Arri PL Mount 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.
Winner: Tied — It depends on your gear
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
Both lenses share the same aperture of 2 — this means that you may buy both Atlas Orion 21mm T2 2x and Canon RF 85mm F2 MACRO IS STM in this regard; they''re the same.
Winner: Tied
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
Winner: Atlas Orion 21mm T2 2x
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 Atlas Orion 21mm T2 2x 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.
5. Autofocus Comparison
In regards to autofocus, the winner is Canon RF 85mm F2 MACRO IS STM since the other lens in this comparison, the Atlas Orion 21mm T2 2x does not have autofocus at all — it is a manual focus lens.
Winner: Canon RF 85mm F2 MACRO IS STM
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
Res
Winner: Canon RF 85mm F2 MACRO IS STM
Regarding macro: Macro lenses can focus much closer to your subjects and might be suitable when photographing flowers, insects, wildlife and nature.
7. Full Frame Comparison
Canon RF 85mm F2 MACRO IS STM covers a full frame sensor while Atlas Orion 21mm T2 2x does not. If you have a full frame camera then Canon RF 85mm F2 MACRO IS STM is the only choice for you in this comparison.
Winner: Canon RF 85mm F2 MACRO IS STM
Regarding full frame coverage: All lenses do not cover full frame sensors, but not all cameras are full frame cameras either. If a lens covers a full frame sensor it can be used on all cameras with a matching lens mount, both full frame and crop sensors, except for medium format cameras.
