EF lenses are compatible with EF-S cameras, but there are some limitations to consider. EF lenses are designed for Canon's full-frame cameras, while EF-S lenses are made specifically for Canon's APS-C sensor cameras. The main difference lies in the image circle projected onto the camera's sensor, with EF lenses covering a larger area to accommodate the full-frame sensor. When using an EF lens on an EF-S camera, the camera automatically crops the image to match the smaller APS-C sensor, resulting in a longer effective focal length due to the crop factor. This means that a 50mm EF lens on an EF-S camera will behave like an 80mm lens due to the 1.6x crop factor of Canon APS-C cameras.
While EF lenses can physically be mounted on EF-S cameras, there may be compatibility issues with certain lenses, particularly older EF lenses. Some EF lenses may have protruding rear elements that interfere with the smaller mirror in EF-S cameras. Canon has introduced the EF-S lens electronic contact feature in newer EF-S cameras to address this problem. Additionally, EF-S cameras may not offer the same level of autofocus performance with certain EF lenses.
It's worth noting that Canon has been focusing on developing EF-S lenses tailored for their APS-C sensor cameras, optimising performance and features for this format. Therefore, while EF lenses can be used on EF-S cameras, it is recommended to consider EF-S lenses for optimal compatibility and performance on Canon APS-C sensor cameras.

What You'll Learn
EF lenses can be used on EF-S cameras with a crop factor
EF lenses are compatible with EF-S cameras, but there are some limitations and considerations to keep in mind. EF lenses are designed for Canon's full-frame cameras, while EF-S lenses are designed for Canon's APS-C sensor cameras. The main difference between the two types of lenses is the image circle they project onto the camera's sensor. EF lenses project a larger image circle to cover the full-frame sensor, while EF-S lenses project a smaller image circle that is specifically designed for the smaller APS-C sensor.
When an EF lens is mounted on an EF-S camera, the smaller sensor size results in a crop factor. This means that the effective focal length of the lens is increased, providing a narrower field of view compared to when the same lens is used on a full-frame camera. For example, a 50mm EF lens mounted on an EF-S camera will have an effective focal length of around 80mm due to the crop factor. It is important to note that the crop factor is not a property of the lens but of the camera's sensor size. The lens will produce the same field of view on a camera with a larger sensor.
While EF lenses can physically be mounted on EF-S cameras, not all EF lenses are fully compatible. Some EF lenses, especially older models, may have protruding rear elements that can interfere with the smaller mirror in EF-S cameras. Canon has introduced a feature called "EF-S lens electronic contact" in newer EF-S cameras to address this issue. This feature allows the camera to detect if an incompatible lens is mounted and displays a warning message.
It is worth mentioning that Canon has been focusing more on developing EF-S lenses specifically for their APS-C sensor cameras. These lenses are designed to take full advantage of the APS-C sensor and offer improved performance and features. Therefore, while EF lenses can be used on EF-S cameras, it is recommended to consider EF-S lenses for optimal compatibility and performance.

EF lenses can be mounted on EF-S cameras but with restrictions
EF lenses can be mounted on EF-S cameras, but there are some restrictions and considerations to keep in mind. Firstly, it's important to understand the difference between EF and EF-S lenses. EF lenses are designed for Canon's full-frame cameras, while EF-S lenses are specifically designed for Canon's APS-C sensor cameras. The main distinction lies in the image circle they project onto the camera's sensor. EF lenses produce a larger image circle to cover the full-frame sensor, whereas EF-S lenses create a smaller image circle tailored for the APS-C sensor.
When EF lenses are mounted on EF-S cameras, the camera automatically crops the image to match the smaller APS-C sensor size. Consequently, the effective focal length of the EF lens increases due to the crop factor. For instance, a 50mm EF lens used on an EF-S camera will yield an effective focal length of approximately 80mm. This extended focal length can be advantageous for telephoto photography. However, it's important to be mindful that wide-angle lenses may not provide the same broad field of view as they would on a full-frame camera.
It is worth noting that not all EF lenses are fully compatible with EF-S cameras. Some older EF lenses may not communicate seamlessly with EF-S cameras, resulting in limited functionality. Additionally, certain EF lenses might have protruding rear elements that can interfere with the smaller mirror in EF-S cameras. Canon has introduced the "EF-S lens electronic contact" feature in newer EF-S cameras to address this issue by detecting incompatible lenses and displaying a warning message.
In summary, while EF lenses can be mounted on EF-S cameras, the crop factor and compatibility limitations should be taken into account. The crop factor alters the effective focal length, and certain EF lenses may not be fully supported by EF-S cameras. It is recommended to refer to specific lens and camera body compatibility information before making any purchases.

EF lenses are generally compatible with EF-S cameras
When using an EF lens on an EF-S camera, the camera will automatically crop the image to match the smaller APS-C sensor size. This results in a longer effective focal length due to the crop factor. For example, a 50mm EF lens on an EF-S camera will behave like an 80mm lens due to the 1.6x crop factor. It's important to note that this crop factor is a result of the smaller sensor size and not the lens itself.
While EF lenses can physically be mounted on EF-S cameras, there may be compatibility issues with certain lenses, especially older EF lenses. Some EF lenses may have protruding rear elements that interfere with the smaller mirror in EF-S cameras. Canon has introduced the "EF-S lens electronic contact" feature in newer EF-S cameras to address this issue by detecting incompatible lenses and displaying a warning message.
It's worth mentioning that EF-S lenses are not compatible with full-frame cameras due to their physical design. They protrude further into the camera body, which would interfere with the larger mirror and sensor of a full-frame camera. Canon has also introduced EF-S lenses specifically designed for APS-C sensor cameras, optimizing their performance for this format.
In summary, while EF lenses can be used on EF-S cameras, there may be limitations and considerations regarding compatibility, field of view, and autofocus performance. It is recommended to check the compatibility of specific lenses and camera bodies before making a purchase.

EF lenses can be used on EF-S cameras with certain limitations
Despite this difference, EF lenses can be used on EF-S cameras. The EF-S camera will automatically crop the image to match the smaller APS-C sensor size. This results in a crop factor that increases the effective focal length of the lens, providing a narrower field of view compared to when the same lens is used on a full-frame camera. For example, a 50mm EF lens used on an EF-S camera will have an effective focal length of approximately 80mm.
However, there are some limitations when using EF lenses on EF-S cameras. EF-S cameras may not have the same level of compatibility and autofocus performance with certain EF lenses, particularly older models. Some older EF lenses may not fully communicate with the EF-S camera, resulting in limited functionality. Additionally, the smaller mirror box in EF-S cameras can cause compatibility issues with certain EF lenses, as the rear elements of the lens may protrude too far into the camera body and interfere with the mirror movement.
It is worth noting that Canon has introduced a few EF-S lenses that are specifically designed for APS-C sensor cameras and are not compatible with full-frame EF cameras. These lenses are designed to take full advantage of the APS-C sensor and offer improved performance and features. Therefore, while EF lenses can be used on EF-S cameras, it is recommended to consider EF-S lenses for optimal compatibility and performance.

EF-S lenses are designed for Canon's APS-C sensor cameras
Canon EF-S lenses are designed for Canon APS-C sensor cameras. The "S" in EF-S stands for "Small image circle" and "Short back focus". The EF-S lens mount is a derivative of the EF lens mount, created for some Canon digital single-lens reflex cameras with APS-C-sized image sensors.
The EF-S mount was introduced in 2003 with the release of the EOS 300D/Digital Rebel/Kiss Digital camera. All consumer to mid-range digital EOS cameras released since then have been both EF and EF-S compatible.
EF-S lenses are designed to produce a smaller image circle of even illumination, which matches the smaller sensor size of APS-C cameras. This allows lens elements to protrude further into the camera body, reducing the minimum distance between the sensor and the back element of the lens. This combination of a smaller sensor and shorter back focal length distance enhances the possibilities for wide-angle and very wide-angle lenses.
EF-S lenses are also designed to be lightweight and compact, providing additional versatility and flexibility for photographers. They are often more affordable than their EF counterparts, making them a popular choice for amateur photographers.
It is important to note that EF-S lenses are not compatible with full-frame sensor cameras or 35mm film cameras. Attempting to mount an EF-S lens on an EF-only camera can cause physical obstruction and damage to the lens and/or camera.
In summary, EF-S lenses are specifically designed for Canon EOS DSLR cameras with APS-C sensors, offering advantages such as reduced size, weight, and cost, while also providing enhanced capabilities for wide-angle photography.
