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.

Delta Development Team and The Good Drone Company Awarded U.S. Army Contract for Aerial Blood Delivery

Published

on

By

TUCSON, Ariz., Oct. 20, 2026 /PRNewswire/ — Delta Development Team (DDT), a leader in prehospital blood storage and cold chain technology, and The Good Drone Company (GDC) have been awarded a U.S. Army contract to develop a drone-based blood delivery capability for the Army Blood Link (ABL) program.

The program is part of the broader Armed Services Blood Program (ASBP), which supplies blood products to U.S. military forces worldwide. Army Blood Link is designed to support battlefield medical logistics through rapid, temperature-controlled delivery of lifesaving blood products to the field, providing an additional resupply option when traditional ground transportation is unavailable, delayed, or unsafe. Under the contract, The Good Drone Company will provide two U.S.-built prototypes of its hybrid vertical takeoff and landing (VTOL) cargo drone, each designed to transport up to six units of blood, while DDT will provide the temperature-controlled storage capability through its Delta ICE 2L Smart Blood Cooler.

The companies are combining commercial off-the-shelf (COTS) technologies to create a U.S.-sourced aerial blood delivery system capable of transporting blood directly to the point of need.

To meet ABL program requirements, DDT will supply six Delta ICE 2L Smart Blood Coolers, each designed to maintain two units of blood within the required temperature range for three hours of aerial delivery in high-humidity environments with ambient temperatures ranging from 15°F to 120°F. Built-in temperature monitoring and data recording, along with Bluetooth and cellular connectivity, support cold-chain oversight and blood accountability. The program extends DDT’s blood storage and monitoring capabilities into aerial delivery.

“Getting blood to the point of need is only part of the challenge. It must also remain within the required temperature range throughout the journey,” said Montgomery Leija, CEO of Delta Development Team. “This program brings DDT’s experience in blood storage and cold chain management into a new operational environment, taking the blood supply chain from the ground to the air.”

The prototype system is designed to deliver blood within 10 meters of a designated target during both day and night operations. It will feature a communications range of up to 30 miles and semi-autonomous waypoint navigation. It is intended for single-person operation with minimal training and is built on GDC’s existing commercial cargo drone technology to accelerate development and fielding while meeting U.S.-sourcing requirements.

“We have seen strong interest in middle-mile drones in emerging markets for some time, from both public and private sector customers spanning healthcare to third-party logistics,” said Jake Vander Ploeg, CEO of The Good Drone Company. “This program is a great example of how the military is adopting commercial technology like our cargo drones to quickly test new ideas in the field without starting a full aircraft development program.”

The collaboration combines GDC’s expertise in commercial drone platforms and aerial delivery with DDT’s temperature-controlled blood storage and transport capabilities to support:

Rapid resupply: Delivering blood when conventional ground transportation is unavailable or unsafe.Cold chain protection: Maintaining required blood temperatures during aerial transport.U.S.-sourced capability: Supporting domestic defense supply chain objectives.Accelerated development: Combining GDC’s existing commercial cargo drone technology with DDT’s established blood storage solutions.

The ABL effort addresses the challenge of delivering critical medical supplies in contested and austere environments. When terrain, damaged infrastructure, or tactical conditions prevent conventional resupply, aerial delivery combined with temperature-controlled storage can expand options for getting lifesaving blood products to service members when and where they are needed.

About Delta Development Team

Delta Development Team (DDT) is a U.S.-based medical technology company headquartered in Tucson, Arizona, specializing in blood storage, transport, monitoring, and logistics solutions for military and prehospital environments. DDT develops technology designed to keep blood available, traceable, and mission-ready from the blood bank to the point of injury. Its portfolio includes the APRU 6L, Delta ICE 2L, TBS 40L, and BloodCOMM® blood management platform.
