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.

Earth’s pulse monitored: a review highlights remote sensing time series progress

Published

on

By

As urbanization accelerates and environmental dynamics shift, the need for accurate and timely terrestrial monitoring has never been more urgent. A review has introduced a novel approach to remote sensing time series analysis, integrating multi-source data to enable near real-time monitoring. This innovative methodology promises to transform environmental conservation and urban planning by providing unprecedented insights into terrestrial changes and offering a more precise understanding of environmental dynamics.

GUANGZHOU, China, Dec. 22, 2024 /PRNewswire-PRWeb/ — An international team of researchers from South China Normal University, the University of Connecticut, and the Chinese Academy of Sciences has made a significant breakthrough in remote sensing. Their review, published (DOI: 10.34133/remotesensing.0285) in the Journal of Remote Sensing on December 11, 2024, addresses key challenges in remote sensing, such as incomplete data and noise interference. The team’s new time series analysis technique leverages advanced data reconstruction and fusion methods, significantly enhancing the precision and efficiency of remote sensing for monitoring environmental changes.

The research team has developed an advanced time series analysis technique that combines deep learning algorithms with traditional remote sensing methods to integrate data from various remote sensing sources. This innovative approach allows for the extraction of subtle patterns from large, complex datasets, which is crucial for monitoring critical environmental parameters such as land use and vegetation health. Unlike conventional techniques that struggle with incomplete or noisy data, this new methodology offers enhanced accuracy and more reliable insights into terrestrial dynamics, paving the way for more effective environmental monitoring.

Central to the study’s success is the integration of Long Short-Term Memory (LSTM) networks and Generative Adversarial Networks (GANs) to address the challenges posed by missing or noisy data. The LSTM networks capture temporal trends over time, while the GANs generate synthetic data that mimics real-world observations to fill gaps and correct for atmospheric distortions. This dual approach has resulted in a cleaner, more accurate time series dataset, which was validated against independent ground truth measurements. The researchers demonstrated significant improvements in key vegetation indices, such as the Normalized Difference Vegetation Index (NDVI), setting a new benchmark in the field of remote sensing.

Experts in the field have lauded the study’s potential to revolutionize remote sensing applications. They see the method as a transformative tool for enhancing high-resolution monitoring and extending its coverage, particularly in agricultural surveillance, urban planning, and environmental management. “This method represents a crucial advancement in our ability to monitor environmental changes,” says Professor Fu. “As it evolves, it could play a key role in addressing climate change and other global challenges.”

The methodology’s future applications are vast, especially in global environmental monitoring and supporting sustainable development goals. By integrating multi-temporal data from Landsat and Sentinel-2 satellites, the team has created a framework for accurate and continuous terrestrial analysis. As computational power advances and algorithms improve, this technology is expected to become a vital tool for natural resource management, disaster response, and climate change mitigation. In the years to come, it could provide critical data to help policymakers address pressing environmental issues on a global scale.

ZINZINO AB (PUBL.): ENTERS INTO AGREEMENT TO PROVIDE DIP FINANCING TO ZURVITA INITIATING CHAPTER 11 PROCESS

Published

on

By

GOTHENBURG, Sweden, Dec. 22, 2024 /PRNewswire/ — Zinzino has in a press release dated 20240617 announced that a letter of intent to acquire 100% of the shares in the North American direct selling company Zurvita Inc. “Zurvita or the Company” was signed. Since then, Zinzino has negotiated with the owners of Zurvita Inc. and instead concluded that the purchase of Zurvita’s assets in a Chapter 11 proceeding for the Company is in Zinzino’s best interest.

Zinzino is providing a debtor-in-possession (DIP) financing to Zurvita, which filed for Chapter 11 bankruptcy proceedings on the 20th December 2024. By entering as a financier in Zurvita’s Chapter 11 with loans totaling USD 4.5 million, Zinzino simultaneously makes an offer to acquire the company’s assets via a so-called stalking horse bid. If the bid is accepted, the DIP loan will be converted into part of a debt-settled purchase price, which will be determined after Zurvita has completed the sale process that is subject to higher and better offers in accordance with the applicable terms of Chapter 11. Other bidders have the right to submit bids for Zurvita during the process and if another bid is accepted, Zinzino’s loan will be repaid and certain of its costs associated with the process will be reimbursed. 

Zurvita is a direct selling health company with operations in the United States, Canada and Mexico. The brand portfolio offers a range of innovative health and wellness products. The business has total annual sales of approximately USD 30 million with good gross margins. A potential transaction with Zinzino is expected to add growth through the synergies arising from the joint networks, combined with Zinzino’s test-based product concept. The profitability of the Company will thus be able to develop well by utilizing Zinzino’s existing technical platform and organization.

A visionary mindset, tech first perspective, test-based nutrition at the cellular level and a strong position to capitalize on current trends will form the basis of the new partnership. Following the acquisitions of VMA Life in 2020, Enhanzz in 2022, the strategic partnership with ACN and the recently completed asset acquisition of Xelliss, Zinzino has been looking for further strong investments to maintain its sustainable, profitable growth, strengthen its distribution power, expand into new markets and leverage the product portfolio in new consumer areas.

– “Individualized advice and tailored solutions are the future, and not just in health and wellness,” says Dag Bergheim Pettersen, CEO of Zinzino. “Together, we have years of combined industry experience and everything it takes to drive the modern, personalized shopping experience through direct sales”. Jay Shafer, CEO and co-founder of Zurvita, states “After considering multiple options for the company and under the guidance of our attorneys and third-party advisors, we feel this presents the best opportunity to continue Zurvita’s mission, deliver the highest quality products, and provide continuity for our staff and consultants. We are excited to see what the future holds for Zurvita.”

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.
