Vazen 40mm T2 1.8x Anamorphic vs Canon EF 40mm f/2.8 STM
Vazen 40mm T2 1.8x Anamorphic vs Canon EF 40mm f/2.8 STM
When comparing Canon EF 40mm f/2.8 STM and Vazen 40mm T2 1.8x Anamorphic, which one is better?
1. Lens Mount Comparison
The lenses each feature different lens mounts — the Vazen 40mm T2 1.8x Anamorphic features a Micro Four Thirds while the Canon EF 40mm f/2.8 STM features a Canon EF — 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
The Vazen 40mm T2 1.8x Anamorphic has the largest aperture of the two lenses at 2 compared to the 2.8 aperture of Canon EF 40mm f/2.8 STM. This means that you get more light to your sensor using Vazen 40mm T2 1.8x Anamorphic wide open, and therefore it might be a better lens in dark situations.
Winner: Vazen 40mm T2 1.8x Anamorphic
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: Vazen 40mm T2 1.8x Anamorphic
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 Vazen 40mm T2 1.8x Anamorphic or Canon EF 40mm f/2.8 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.
