Photography News: Canon has released three new RF-mount zoom lenses: the RF 24-105mm f/2.8 L IS USM Z, the RF 200-800mm f/6.3-9 IS USM, and the RF-S 10-18mm f/4.5-6.3 IS STM

NEW YORK, Nov. 2, 2023 /PRNewswire/ — B&H is pleased to introduce three RF zoom lenses from Canon: RF 24-105mm f/2.8 L IS USM Z, the RF 200-800mm f/6.3-9 IS USM, and the RF-S 10-18mm f/4.5-6.3 IS STM. Each of these lenses appeals to a different application and shooter type, with the 24-105mm f/2.8 featuring a speedy f/2.8 maximum aperture and compatibility with an optional Power Zoom Adapter; the 200-800mm hitting a special place in the portable, hand-holdable super-telephoto world; and the APS-C-specific 10-18mm combining ultra-wide performance with a compact design to suit the needs of vloggers.

The Canon RF 24-105mm f/2.8 L IS USM Z stands out for a few reasons; namely, the bright f/2.8 lens is an impressive feat compared to the f/4 speed typically associated with this zoom range. This is the first 24-105mm lens to have a constant f/2.8 maximum aperture, giving it the speed you’d associate with professional 24-70mm lenses, along with the extra reach at the telephoto end. It’s going to be the go-to lens for many creator types, especially those working in a hybrid capacity with a substantial emphasis on video.

The second lens of the day is an impressively versatile super-telephoto zoom, the RF 200-800mm f/6.3-9 IS USM. Aimed squarely at enthusiast wildlife, nature, sports, and bird photographers, as well as those looking to produce some dramatic compositions of distant landscapes, this is a relatively compact and portable lens offering a huge focal length range in a manageable package. It weighs 4.5 lb, measures just over 12″ in length, and has 5.5-stop effective optical IS at 800mm—it’s a lens that can be handheld, especially in midday conditions, but also features an integrated mount for sure use atop a monopod or a tripod.

In the RF lineup, this lens fills a gap in the already pretty deep telephoto range: it sits next to the Canon 100-500mm f/4.5-7.1 L, offering greater reach with a slight penalty on weight and speed, and serves as a faster, more versatile alternative to some of the lightweight prime super-telephoto options, like the 600mm f/11 and 800mm f/11.

In case the reach of this zoom isn’t long enough, this 200-800mm f/6.3-9 is compatible with the optional Extender RF 1.4x and Extender RF 2x teleconverters, resulting in effective 280-1120mm f/9-13 and 400-1600mm f/13-18 options, respectively.

Despite this lens not being an L Series lens, it does still feature several upgraded design assets, including a weather-resistant design, UD glass elements, an SSC multicoating, a Nano USM AF system, and the characteristic white paint exterior.

This is going to be a very enticing lens for budding wildlife and sports photographers, especially those looking to invest in super-telephoto optics without the hefty price tag of some of the more exotic primes. This lens gives a high degree of versatility in a very practical configuration.

Canon RF-S 10-18mm f/4.5-6.3 IS STM – Compact Ultra-Wide Zoom for Vloggers and Creators

Finally, Canon’s trifecta of new zooms with the smallest option, the RF-S 10-18mm f/4.5-6.3 IS STM. Compared to the other two, this is a decidedly petite option built for vloggers and content creators working with APS-C-format RF-mount cameras, like the EOS R100, R50, R10, and R7, and offers a 16-28.8mm equivalent focal length range.

Canon is positioning this lens for vlogging and selfie video productions, due to its light weight and ultra-wide field of view, but it also makes a great compact option for travel, landscape, and cityscape shooting. It also has an impressive minimum focusing distance of 5.5″ with AF or 3.4″ with MF, making it an interesting choice for ultra-wide close-up shooting.

The lens has 4-stop effective optical IS, supports up to 6 stops of shake control with Coordinated IS, and can be used in conjunction with Movie Digital IS for stable handheld video footage. Also, the STM AF system offers smooth and silent focusing performance that’s great for stills and video. This 10-18mm matches other RF-S-series lenses with a sleek and retractable design; it weighs just 5.3 oz and measures 1.8″ long.

Additionally, Canon introduced PZ-E2B and the PZ-E2 Power Zoom Adapters that enables complex zoom control for the Canon RF 24-105mm f/2.8 L IS USM Z lens. Zoom speed of the DC motor can be adjusted via a dial in a stepless manner to allow rapid and low-speed zooming. The PZ-E2B draws power from the camera through contacts on the lens.

Meet With Culture: Exquisite Craftsmanship of Traditional Chinese Architecture

Published

on

By

BEIJING, Dec. 22, 2024 /PRNewswire/ — The Temple of Agriculture in Beijing played a significant role during the Ming (1368-1644) and Qing (1644-1911) dynasties. Over nearly 600 years, 25 emperors personally visited or sent ministers to perform spring farming ceremonies and offer sacrifices to Shennong, the god of agriculture.

 

Built in 1420 during the Yongle reign, the temple’s predecessor was the Temple of Mountains and Rivers in Nanjing. When Emperor Zhu Di moved the Ming capital to Beijing, he constructed a larger temple inspired by the Nanjing temple, which gradually evolved into the Temple of Agriculture.

The Taisui Hall, the largest building complex in the temple, now serves as a major exhibition hall of the Beijing Ancient Architecture Museum, showcasing models of classical Chinese buildings and demonstrating the solemnity of royal architecture.

Ancient Chinese architecture is predominantly wooden-structured, chosen for its availability, versatility, and earthquake resistance. Artisans developed sophisticated techniques in material selection and construction. The wooden framework consists of columns, beams, girders, and purlins, with innovative structural forms like lifting-beam and piercing-bracket structures.

A unique architectural element is the dougong (bracket sets), which supports weight and connects beam frames with column walls. Mortise-tenon joints were invented to create elastic frameworks by connecting different components.

While discussing the Temple of Agriculture, it’s worth noting another remarkable example of architectural hierarchy which could be found in the Temple of Heaven. The hierarchy of architectural designs reflected social stratification, with eave structures like the triple-layered eaves of the Hall of Prayer for Good Harvest representing the highest-level architectural design.

Over centuries, the Temple of Agriculture has transformed from an imperial garden to a public park and a museum for historical architecture, now standing as a significant cultural landmark that symbolizes China’s agricultural civilization and architectural heritage along Beijing’s Central Axis.

Quickly join Alexandre to study and explore the traditional Chinese architecture.

Patent leverages AI technology to improve patient outcomes and reduce cost of care

DANA POINT, Calif., Dec. 22, 2024 /PRNewswire-PRWeb/ — SecondOpinionExpert, Inc. (SOE), a leading healthcare technology company, announced today that it has filed patent application 133902-0002UT01 with the United States Patent and Trademark Office entitled “Method and Apparatus for Generating Automated Medical Opinions Using Artificial Intelligence.” The patent covers the company’s proprietary system that communicates a medical opinion to a user based on a trained model that uses artificial intelligence (AI) or machine learning (ML).

“In the near future, we’ll launch our free app, enabling users to access high-quality medical opinions. This innovative app empowers individuals with insightful medical guidance that improves health and saves lives,” said Steve Krause, President of SecondOpinionExpert, Inc.”

Medical second opinions have traditionally been obtained by seeking out another healthcare professional who reviews the patient’s medical records, diagnoses, and tests. However, the rapidly increasing complexity of medical information, the demand for faster turnaround times, and the limitations of human expert availability have created a need for automated systems that utilize AI to generate both first and second medical opinions.

Artificial intelligence has made significant strides in medical diagnostics, including image recognition, predictive modeling, and natural language processing (NLP). These advancements present an opportunity to augment traditional second opinion systems by automatically processing patient medical records, diagnostic tests, and clinical data to generate high-quality first and second medical opinions.

SecondOpinionExpert’s technology increases the quality and efficiency of healthcare delivery, improves healthcare access and empowers doctors and patients to make better informed medical decisions. The HIPAA-compliant patented platform leverages recent advancements in artificial intelligence, machine learning and electronic medical record systems enabling the company to provide fast, reliable and secure online medical opinions. The system provides patients greater peace of mind by leveraging the power of AI and ML.

“Our patent-pending AI enabled technology platform provides a cost-effective choice that improves patient care,” said Steve Krause, President, SecondOpinionExpert, Inc. “In the near future, we look forward to launching our user-friendly app that will be initially free of charge. People using our platform will be able to quickly obtain high quality medical opinions while avoiding unnecessary travel time and expense, knowing that they will be getting insightful medical guidance that improves health and saves lives.”
