Sigma 28-45mm F1.8 DG DN Art Lens - L-mount

The Sigma 28-45mm F1.8 DG DN Art for L-mount cameras is a versatile full-frame lens that delivers sharpness and clarity comparable to that of a prime lens throughout its entire zoom range. It's the world's first full-frame zoom lens with a maximum aperture of F1.8 and weighing in at just 960g, it is ideal for hand-held shooting or a gimbal setup. This lens also features high-speed and adaptable autofocus, a durable weather-resistant structure, de-clickable aperture ring and smooth manual focusing - perfect for both filmmakers and photographers.

Optical quality
Through the effective arrangement of 5 SLD elements and 3 aspherical elements, aberrations are rigorously corrected. Axial chromatic aberration, which is particularly noticeable with large-aperture lenses, has been thoroughly suppressed, and the lens delivers clear images with minimal colouration, from sharply focused details to large, smooth bokeh.

Fast focus with a linear motor
The lens’s AF mechanism uses an HLA (High-response Linear Actuator) to combine accelerated focusing speed with exquisite precision. And because the motor is near-silent it allows video recording without noise.

Precise manual focusing
To deliver delicate and accurate manual focus, the lens employs a bi-wire driven focus ring with optimum torque setting, high resolution and an adjustable rotation angle between 90° and 720°. This allows film-makers to pull focus with organic smoothness, and photographers to focus manually with outstanding accuracy.

Suppression of focus breathing
When using regular lenses, the angle-of-view can change as focus moves from near to far, affecting precise composition. With the SIGMA 28-45mm F1.8 DG DN | Art this focus breathing is suppressed, enabling natural focus pulls when shooting video.

Inner zoom
Employing an inner zoom mechanism, the overall length of the lens remains constant when the focal length or focus distance changes. This means the lens is easy to use when shooting hand-held, highly stable when mounted on a tripod or gimbal, and more resistant to dust and water contamination.

Close focus
The minimum focusing distance is a constant 30cm across the entire zoom range, with a maximum magnification ratio of 1:4 at the telephoto end, providing excellent close-up shooting capabilities. As well as offering precise focus in confined spaces, the lens can therefore be used close to a subject without affecting sharpness when using the zoom.

Minimal flare and ghosting
Flare and ghosting, which reduce image quality, have been largely eliminated using advanced simulation technology, ensuring the lens renders rich, high-contrast results in all conditions. In addition, in order to keep flare and ghosting to a minimum, the lens uses SIGMA’s Nano Porous Coating and Super Multi-Layer Coating, producing superior resistance to backlighting and enabling clear, saturated images in all lighting conditions.

Rugged build
In addition to a dust and splash-resistant body, the frontmost surface of the lens is coated with a water and oil-repellent coating so that it can be used safely even in harsh outdoor environments.
