Sony lenses

Sony offers a wide range of lenses for its mirrorless cameras: full-frame (FE) and APS-C format lenses.

Full-frame and APS-C format Sony lenses are designed to work with different sensor sizes and camera systems, and understanding the differences between the two can be important when choosing the right lens for your camera.

Full-frame Sony lenses are designed to work with full-frame sensors, which are the same size as traditional 35mm film. Full-frame sensors offer a larger surface area than APS-C sensors, meaning they can capture more light and detail. Full-frame lenses are typically more expensive than APS-C lenses and tend to be larger and heavier due to the larger image circle required to cover the full sensor.

APS-C format Sony lenses, on the other hand, are designed to work with APS-C sensors, which are smaller than full-frame sensors. APS-C sensors have a crop factor of 1.5x or 1.6x, depending on the camera manufacturer, which means that they capture a smaller portion of the image circle produced by the lens. APS-C lenses are typically smaller and lighter than full-frame lenses, and are often less expensive.

While full-frame lenses can be used on APS-C cameras, the crop factor means that the effective focal length of the lens will be multiplied by the crop factor. For example, a 50mm lens used on an APS-C camera with a crop factor of 1.5x would have an effective focal length of 75mm. This can be advantageous for certain types of photography, such as wildlife or sports, where a longer effective focal length can be useful.

APS-C lenses, on the other hand, cannot be used on full-frame cameras without vignetting, as the image circle produced by the lens is too small to cover the entire sensor.

Overall, the choice between full-frame and APS-C format Sony lenses depends on several factors, including your camera system, your shooting style, and your budget. While full-frame lenses are generally considered to be of higher quality, they may not always be necessary for every type of photography, and APS-C Sony lenses can be a more affordable and lightweight alternative.
