Overview
The Sigma 105mm ƒ/2.8 DG DN Macro Art Photography Lens with L-Mount is a telephoto prime covering Full Frame sensors. Telephoto focal lengths flatten perspective and lift a subject clear of its background, which portrait and sports photographers rely on. 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 L-Mount. Closest focus is 11.6 in, for a maximum magnification of 1:1.
Features
Key Features
Telephoto Full Frame Coverage
The lens covers Full Frame sensors. A telephoto field of view compresses distance and separates a subject from its background, the range portrait and sports photographers work in.
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.
1:1 Maximum Magnification
At life size the lens projects a subject onto the sensor as large as it is in reality, which is the threshold for true macro work and the range product and nature photographers use for detail.
De-clickable Aperture Ring
The aperture ring can be switched between clicked and clickless. Clicked stops give repeatable exposure by feel for stills; clickless allows a silent, stepless iris pull during video, which is why the switch matters to anyone shooting both.
Aperture Control
Hybrid Aperture Control
Aperture can be set either on the ring or electronically from the camera body, so the lens suits a photographer working from the barrel and a hybrid shooter driving exposure from the body without either giving anything up.
Mount & Build
L-Mount
The lens mounts via L-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.
Weather-Sealed Construction
Seals at the mount and control rings resist dust and moisture, which matters for landscape and field sports work carried out in the open.
