Key Specs
- Lens Mount Compatibility: Sony E-Mount
- Lens Type: Other
- Minimum Focal Length: 21 millimeters (The minimum distance between the lens and the image sensor that allows the subject to be in focus. The shorter the focal length, the greater the area of scene captured.)
- Maximum Focal Length: 21 millimeters (The maximum distance between the lens and the image sensor that allows the subject to be in focus. The greater the focal length, the smaller the area of scene captured.)
- Maximum Aperture: f/2.8 (The limit to how wide a lens can be open, typically expressed in f-numbers. The smaller the number, the larger the aperture and the more light that can enter the lens. A larger aperture creates a shallower depth of field, helpful for keeping subjects in focus and blurring background details.)
