SIGMA 28-45mm F1.8 Maximum Aperture DG DN Art Lens with Internal Zoom and HLA Autofocus (L Mount)

Capture images that inspire with the SIGMA 28-45mm F1.8 DG DN Art Lens, the world’s first full-frame f1.8 maximum aperture zoom lens. It is a successor of the SIGMA 18-35mm F1.8 DC HSM Art (for APS-C DSLR cameras). It features 3 aspherical lens elements and 5 SLD glass elements that deliver spectacular results and the ultimate bokeh effect. The outstanding performance of the lens can be compared to single focal length lenses, even better than the SIGMA 24mm F1.4 DG DN Art and SIGMA 50mm F1.4 DG DN Art. It suppresses axial chromatic aberrations and minimizes ghosting and flare for crystal-clear images with intricate details. The lens has a minimum focusing distance of 30cm (11.8 inches) throughout the entire range, and a maximum magnification ratio of 1:4 at 45mm focal length. Experience minimal focus breathing with the advanced internal zoom and HLA (High-response Linear Actuator) autofocus. The SIGMA 28-45mm F1.8 DG DN Art Lens is ideal for video work including gimbal setup. It features a click or de-click switch and has a lockable aperture ring that is perfect setting personal preferences. The dust- and splash-resistant design is the cherry on the cake, making it versatile for use in not-so-favorable shooting environments.

The SIGMA 28-45mm F1.8 DG DN Art Lens is the world's first full-frame zoom lens with a maximum aperture of F1.8. It features an inner zoom mechanism, and boasts a minimum focusing distance of 30cm across the entire zoom range. The lens has a filter size of 82mm phi.

The F1.8 aperture of this lens makes it at par with most prime lenses. It offers the user of a full-frame camera to expose hand-held in low-lit surroundings to produce stunning bokeh, all this while making the most of a flexible zoom. This advance feature is a brainchild of SIGMA’S production base in Aizu, Japan.

This lens features an inner zoom which enables the length of the lens to remain constant even if focal length or focus distances change. This is extremely helpful while shooting hand-held. It also offers the advantage of mounting the lens on a tripod or gimbal, and maintains its resistance to dust and water contamination.

The focus distance of the lens remains 30cm across the entire range with a maximum magnification of 1:4 at the telephoto end which means that it maintains image sharpness when using zoom, despite being close to the subject. This allows easy close-up shooting and is perfect for use in confined spaces. 

Fast zoom lenses are expected to be bulky and heavy, however this SIGMA Lens weighs under 1kg while offering a versatile filter size of phi 82mm. It is powerful and sturdy, yet lightweight and portable.

The SIGMA 28-45mm F1.8 DG DN Art lens corrects each optical aberration meticulously throughout the zoom range. Its advanced coatings help the lens to produce crystal-clear images, even in low-lit environments.

High-Quality in a Zoom 

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 coloration, from sharply focused details to large, smooth bokeh.

The SIGMA 28-45mm F1.8 DG DN Art lens suppresses breathing and corrects angle-of-view change even when the focus moves from near to far.

SIGMA's lens features Nano Porous Coating and Super Multi-Layer Coating that offers superior resistance to backlighting. This cuts down ghosting and flare to a great extent to deliver rich and clear images in all lighting conditions.
