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

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.

The Hottest Dog Bronchial Health Supplement on Shopee in 2024

Published

on

By

SEOUL, South Korea, Nov. 10, 2024 /PRNewswire/ — As a dog owner, you may have often heard your furry friend coughing, whether it’s a dry hack or a honking sound. Though it might seem trivial, these coughs can cause serious discomfort for your furry friend and create anxiety for you as a caring pet parent.

DOCTORBY’s BREATH CARE is a nutritional supplement designed to support bronchial health in dogs, currently gaining attention among many pet owners on Shopee.

Coughing in dogs can be triggered by various factors, including temperature fluctuations, strong air conditioning, and dust or debris inhaled during walks. Additionally, as dogs age, their bronchial immunity can weaken, leading to potential health issues.

BREATH CARE contains a blend of functional ingredients like the plant-based complex extract TF-343, magnesium, and propolis, which can help alleviate respiratory issues such as coughing and support the elimination of waste accumulated in the bronchial passages.[1] With a taste dogs love, it doubles as a treat, making it incredibly easy for pet owners to administer. Furthermore, it has passed heavy metal and toxicity tests, ensuring safety without the use of synthetic sweeteners or colorings.

Currently, BREATH CARE ranks as one of the top products in Shopee’s pet nutrition and supplement category. In May 2024, it achieved the number one sales position in the pet nutrition category on Shopee Singapore, garnering immense popularity. Shopee has reported a staggering 3,000% growth in sales compared to 2023. Notably, DOCTORBY has not only topped the charts on Shopee but has also held the number one position on Amazon Japan for 22 consecutive weeks, establishing itself as a leader in the South Korean pet nutrition market and rapidly expanding in the global market.

For cat owners, the cat-specific bronchial supplement, CAT BREATH CARE, is also enjoying tremendous popularity. Additionally, DOCTORBY offers a variety of health supplements, including ‘SKIN & COAT’ for skin support, ‘EYES CARE’ for eye health and tear stain improvement, and ‘HAIRBALL CARE’ to assist with hairball elimination in cats. In Singapore, DOCTORBY products are exclusively available on Shopee.

Enjoy fast delivery via Shopee’s reliable fulfillment services, with most orders arriving within 2 to 3 days for a satisfying shopping experience. Shopee also hosts monthly promotional events, such as Double Day and Pay Day, offering a range of exciting deals. Moreover, a special Mega Day event is planned for November 11, promising additional benefits for shoppers.

LG Display Succeeds in Developing World’s First Stretchable Display that Expands by 50 Percent

Published

on

By

SEOUL, South Korea , Nov. 9, 2024 /PRNewswire/ — LG Display, the world’s leading innovator of display technologies, announced today its unveiling of the world’s first Stretchable display capable of expanding up to 50%, the highest rate of elongation in the industry. At LG Science Park in Seoul on Nov. 8, the company demonstrated the panel at a meeting of more than 100 South Korean industry, academia, and research stakeholders involved in a Stretchable display national project.

Stretchable displays are seen as the ultimate free-form screen technology because they can be freely transformed into any shape, including by stretching, folding, and twisting.

The new prototype features a 12-inch screen that stretches up to 18 inches, while simultaneously delivering a high resolution of 100ppi (pixels per inch) and full red, green, and blue (RGB) color.

Compared to the first Stretchable display prototype unveiled in 2022, the new panel’s maximum elongation rate has more than doubled from 20% to 50%. This enhanced stretchability enables various display design possibilities, raising the technology’s potential competitiveness when commercialized.

By applying a number of new technologies, such as improving the properties of a special silicon material substrate used in contact lenses and developing a new wiring design structure, LG Display improved the panel’s stretchability and flexibility, exceeding the original national project’s target of 20% elongation.

In addition, by using a micro-LED light source of up to 40μm (micrometers), the new prototype’s strengthened durability means it can be repeatedly stretched over 10,000 times, maintaining clear image quality even in extreme environments such as exposure to low or high temperatures and external shocks.

Stretchable displays are not only thin and lightweight but also capable of adhering to irregularly curved surfaces like clothing and skin. They are expected to be widely applied in various industries, from fashion and wearables to mobility.

The company showcased numerous concepts for the application of Stretchable displays, including an automotive panel that stretches out into a convex shape and can be operated by hand as well as a wearable display attached to firefighters’ uniforms that provides real-time information.

LG Display was selected as the lead company for the national project to develop Stretchable displays in 2020 and since then has been conducting joint R&D with 19 domestic industry and research institutes. It is one of the major tasks of a wider project to develop core technologies for next-generation displays promoted by South Korea’s Ministry of Trade, Industry and Energy (MOTIE) along with the Korea Planning & Evaluation Institute of Industrial Technology.

By successfully completing the project, LG Display has not only secured core technologies that can lead the next-generation display market but also contributed to localizing materials, components, and equipment as well as building an R&D infrastructure.

“We will continue to build a sustainable future display ecosystem through close cooperation between South Korean industry, academia, and research stakeholders,” said Soo-young Yoon, CTO and Executive Vice President of LG Display.
