Sigma 28-45mm F1.8 Full Frame DG DN Art Lens Announced; YouTube Video First Look, Learn More Info at B&H Photo Video

Published

Photography News: Sigma has released a fast full-frame zoom offering a versatile focal length range, a bright f/1.8 design, and optical performance that rivals a prime.

NEW YORK, June 3, 2024 /PRNewswire/ — B&H is pleased to share the new Sigma 28-45mm f/1.8 DG DN Art lens—a unique full-frame zoom that features a constant f/1.8 maximum aperture and a short wide-angle to normal-length zoom range. This lens is effectively the full-frame mirrorless successor to their popular 18-35mm f/1.8 DC HSM Art lens from nearly a decade ago, serving as a go-to option for filmmakers and photographers looking for a single lens that blends versatility and speed.

 

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.

Simpli5 Announces Platform Expansion Designed to Close the Gap Between Self-Awareness and Team Action

Behavioral intelligence leader addresses the knowing-doing problem that leaves most assessment investments unrealized

AUSTIN, Texas, April 19, 2026 /PRNewswire/ — Simpli5, the behavioral intelligence platform that powers team effectiveness at organizations including LinkedIn, Kaiser Permanente, and Notion, today announced a significant expansion of its platform aimed at solving one of the most persistent challenges in enterprise learning and development: the knowing-doing gap.

While behavioral assessments have proliferated across the Fortune 500, the vast majority of users never return to their insights after initial onboarding — leaving significant organizational investment unrealized. The upcoming Simpli5 release is engineered specifically to close that gap, translating one-time self-awareness into an ongoing team practice embedded in the flow of daily work.

“Self-awareness that lives in a report is just data. Self-awareness that lives in your daily relationships is transformation,” said Karen Wright Gordon, Founder and CEO of Simpli5. “We built this because we knew the highest-value moments in our platform were sitting unused for too many users. These features are about closing that gap without adding friction.”

The expansion introduces a suite of interconnected capabilities designed to keep behavioral insights present in the flow of daily work — accessible at the moments that matter most, and creating reinforcing loops that grow in value as organizational adoption scales.

Unlike point-in-time assessments, Simpli5 is engineered to compound in value over time. Each connection made, each insight applied, and each colleague activated increases the network intelligence available to every user on the platform. The upcoming release is designed to accelerate that compounding effect.

Full feature details and availability will be announced in the coming weeks.

About Simpli5

Simpli5 powered by 5 Dynamics is a behavioral intelligence platform built on the science of five natural work energy phases: Explore, Excite, Examine, Execute, and Evaluate. Unlike static assessment tools, Simpli5 is a living team intelligence platform that deepens in value as adoption scales across an organization. Its AI coaching product, SenSai, delivers personalized behavioral insights at the moment of need.
