Sony FE 12-24mm ƒ/2.8 GM Photography Lens with E-Mount
Overview
The Sony FE 12-24mm ƒ/2.8 GM Photography Lens with E-Mount is an ultra-wide 12-24mm zoom covering Full Frame sensors. Ultra-wide coverage takes in a whole room or a whole horizon from close in, which is why architectural and landscape photographers reach for it. A fast ƒ/2.8 maximum aperture separates subject from background and keeps shutter speeds up as the light falls, closing to ƒ/22. Autofocus lets the camera's own subject detection drive the lens, which is what makes it usable for tracking moving subjects and for video. It mounts via E-Mount. Closest focus is 11 in, for a maximum magnification of 1:7.1.
Features
Key Features
Ultra-Wide Full Frame Coverage
The lens covers Full Frame sensors. An ultra-wide field of view holds an entire landscape or interior in one frame, and is the range architectural and astro work depend on.
ƒ/2.8 Maximum Aperture
A fast ƒ/2.8 aperture separates a subject from its background and holds shutter speed up in poor light, and the lens closes to ƒ/22.
Autofocus
The lens focuses under the camera's control, so hybrid shooters can use the body's own subject detection and tracking rather than pulling focus by hand — the difference between catching a moving subject and losing it.
1:7.1 Maximum Magnification
A maximum magnification of 1:7.1 sets how large a small subject renders on the sensor, with a closest focus of 11 in.
Optical Design
12-24mm Zoom Range
The 12-24mm range covers a scene without a lens change, which travel, event and documentary work depend on.
9-Blade Diaphragm
9 blades hold the iris closer to a circle when stopped down, which keeps out-of-focus highlights round rather than polygonal — visible in portrait backgrounds and night work.
Mount & Build
E-Mount
The lens mounts via E-Mount, which sets the bodies it fits directly and those it reaches through an adapter.
Electronic Lens Communication
Contacts in the mount pass aperture, focus and focal length between lens and body, so exposure data is recorded to EXIF and in-camera corrections for distortion and vignetting apply automatically.
