This Sigma 28-45mm F1.8 DG DN Art single lens can effectively take the place of carrying 28mm, 35mm, and 50mm f/1.8 primes. It will be larger than any of those single primes, though, measuring 3.5 x 6″ and weighing 2.1 lb. Considering it’s a single lens, though, it’s a usable design that’s still suitable for handheld use. Beyond the uniqueness of the speed and zoom range, Sigma is also pushing the optical qualities of this lens and stating that the sharpness and rendering is also comparable to that of prime lenses. Aspherical and low dispersion elements contribute to high sharpness and accurate color rendering and also promote better focus breathing performance. The lens has a minimum focusing distance of 11.8″ throughout the zoom range and, at the 45mm position, offers a 1:4 maximum magnification ratio for close-up work. Coupling the bright f/1.8 design and 11-blade diaphragm, this 28-45mm f/1.8 is a standout choice for shallow depth of field shooting and selective focusing, especially when working with nearby subjects.

In terms of handling, internal zoom and focusing designs are used to maintain the overall lens length and balance while shooting, making this a perfect candidate for video shooters using a gimbal setup or for one-man productions on a mirrorless platform. This non-moving design also adds to overall dust and splash resistance for working in inclement weather conditions. Another physical touch that’s been optimized for video needs is the manual aperture ring, which can be locked in place to prevent accidental switching and can also be de-clicked for smooth and silent iris transitions.
For autofocus, a High-response Linear Actuator (HLA) is used, which achieves fast, quiet, and smooth focusing performance that, again, is also beneficial to solo shooters working handheld or atop a gimbal. And, for L Mount users, the manual focus ring can be set for linear and non-linear focusing depending on the range one needs to cover during a shoot.
