What are the different types of Canon lens mounts?
At Canon we have four different types of lens mount: EF, EF-S, EF-M and RF. Put simply, a lens mount is the interface between a camera body and a lens. This feature allows for interchangeable lenses. Depending on your camera, different lens types can be used with or without a lens mount adapter.
What is the diameter of Canon lens?
There’s no set standard lens diameter size, but there are some common sizes for the diameter of DSLR lenses: 43mm, 49mm, 52mm, 44mm, 58mm, 62mm, 68mm, 72mm, and 77mm.
What is the difference between EF-S and EF-M lenses?
EF-S lenses feature a protective pin that stops these lenses from being mounted on a full-frame EOS camera. EF-M – a new lens format specifically designed for the Canon EOS M mirrorless camera system with EF-M mount. Just like the EF-S lenses, EF-M are designed for APS-C sensor cameras.
Do all Canon lenses fit every Canon camera?
No, crop sensor cameras (all Rebel cameras, 40/50/60D, and the 7D) can take EF or EF-S lenses. Full frame cameras (all 1D, 5D and 6D) only take EF lenses. The mirrorless camera (EOS-M) use EF-M lenses, but can use EF and EF-S with an adapter.
What does EF and RF mean?
RF mount is the new mount from Canon that is used on their lineup of full frame mirrorless cameras. EF mount is the older mount used by Canon in their Film SLR and Digital DSLR cameras (cameras with mirrors in them).
How do I know my lens size?
Eye Size (Lens Width) is the horizontal with the frame’s lens in millimeters. Usually, the eye size ranges from 40 mm to 60 mm. When measuring, please measure the inside of the frame. Lens Height is the vertical height of an eyeglasses lens which is measured from the top to the bottom of the lens excluding the frame.
Does lens diameter make a difference?
Modern DSLR cameras allow a photographer to vary the aperture of their lens, thus changing the f-ratio or speed of their camera. While a larger aperture diameter might increase the brightness and sharpen the focus, increasing the lens magnification will increase the focal length and thus enlarge an image.
Will EF lens fit on EF-S mount?
The short answer to your question is yes, an EF lens can be used on a crop-sensor (EF-S) Canon camera. The longer answer is that EF-S lenses are designed for crop-sensor lenses, the ‘s’ denotes a smaller image circle, but it’s otherwise a compatible mount.
