In Canon terminology, EF-S stands for Electro-Focus Short back focus. These lenses are specifically designed for Canon DSLR cameras with APS-C (crop) sensors, allowing the rear element to sit closer to the imaging sensor. They are lightweight, compact, and incompatible with full-frame cameras.
Key details regarding Canon EF-S lenses:
"Short Back Focus": The rear element of the lens is closer to the sensor, enhancing wide-angle design possibilities.
Compatibility: Designed exclusively for APS-C DSLR cameras (e.g., EOS Rebel series, 7D, 80D, 90D).
Mount Difference: They will not fit on full-frame cameras (e.g., 5D, 6D, 1D series) because they will strike the larger camera mirror.
Image Circle: Smaller, matching the APS-C sensor size rather than full-frame.
Adapter Use: They can be used on Canon EOS M or EOS R mirrorless cameras with the appropriate mount adapter.
Distinction: EF stands for Electro-Focus, the standard lens mount for both full-frame and crop cameras, while EF-S is specifically for crop-sensor models.
