Can I use EF lenses on EF-S cameras?
EF lenses can be used on EF-S cameras, but there are some limitations and considerations to keep in mind. The main difference between EF and EF-S lenses is the image circle they produce. EF lenses produce a larger image circle that covers the entire full-frame sensor, while EF-S lenses produce a smaller image circle that is designed specifically for APS-C sensors. When using an EF lens on an EF-S camera, the lens will still work, but the camera will automatically crop the image to match the smaller sensor size.
This means that the effective focal length of the lens will be increased by a factor of 1.6, due to the crop factor of the APS-C sensor. For example, a 50mm EF lens will have an effective focal length of 80mm on an EF-S camera. Additionally, some EF lenses may not be optimized for use on APS-C sensors, which can result in reduced image quality or vignetting. However, many EF lenses are designed to work well on both full-frame and APS-C cameras, and can provide excellent image quality when used on an EF-S camera.
What is the difference between EF and EF-S lenses?
The main difference between EF and EF-S lenses is the image circle they produce. EF lenses produce a larger image circle that covers the entire full-frame sensor, while EF-S lenses produce a smaller image circle that is designed specifically for APS-C sensors. This means that EF lenses can be used on both full-frame and APS-C cameras, while EF-S lenses are designed specifically for use on APS-C cameras. EF-S lenses are also generally smaller and lighter than EF lenses, since they do not need to produce as large of an image circle.
In terms of image quality, both EF and EF-S lenses can produce excellent results, but EF lenses are often considered to be of higher quality due to their larger image circle and more complex optical designs.
