Sigma expands its Art and Sports lines for mirrorless with a 15mm f/1.4 diagonal fisheye and the handheld-friendly, super-telephoto 500mm f/5.6 lens.

NEW YORK, Feb. 20, 2024 /PRNewswire/ — B&H is pleased to announce new prime lenses from Sigma’s Art and Sports lines for mirrorless cameras: the 15mm f/1.4 DG DN Art and the 500mm f/5.6 DG DN OS Sports lenses. Available in L-mount and Sony E-mount configurations, the pair offers exceptional imaging and professional-grade performance at both ends of the focal-length spectrum.

 

Take a night walk on the wide side with Sigma’s latest astro-centric offering, the 15mm f/1.4 DG DN Art lens. Joining two 14mm lenses and a 20mm lens, this bright, ultra-wide prime distinguishes itself as the line’s only diagonal fisheye. Boasting an expansive 180° angle of view, the lens shares similar optical construction, incorporating Special Low Dispersion (SLD), “F” Low Dispersion (FLD), and aspherical elements to optimize the reproduction of bright points of light. The lens also carries over many of the astro-friendly practical features from its Sigma Art line siblings.

The newest member of the Sigma Sports line, the 500mm f/5.6 DG DN OS Sports lens, combines innovative optics with its advanced OS2 Optical Stabilizer Algorithm, which provides up to five stops of image stabilization, to create a super-telephoto lens designed for handheld shooting. At 4.2 x 9.2″ and weighing 3 lb, the compact and lightweight form factor encourages mobility and benefits wildlife and aviation photography in addition to sports.

Both lenses feature an autofocus system powered by a high-response linear actuator (HLA), bringing speed, precision, and silence for stills and video. The HLA also offers improved following performance for subjects in motion. They also feature dust- and splash-resistant construction and coatings to protect against the elements for use in any environment.

The New DePin: OKZOO’s Environmental AIoT Machine Network Leads New Tech Trend

Published

on

By

HO CHI MINH CITY, Vietnam, April 26, 2025 /PRNewswire/ — The “new DePin” (Decentralized Physical Infrastructure Network) trend is arising, as OKZOO’s AIoT devices see explosive growth and traction.

AIoT is short for AI combined with Internet of Things (AIoT), a new category that bridges physical hardware with decentralized network. OKZOO uses AIoT devices to gather environmental data such as noise pollution, air pollution, CO2 levels, and humidity.

OKZOO has already seen massive adoption with 12 million ecosystem users, primarily through its virtual AI pet apps OKZOO V1 and V2.

How AI Pets and Portal Devices Collect Environmental Data

OKZOO’s development began with an intriguing hypothesis: could engaging pet applications serve as the foundation for sophisticated real-world AIoT networks? The team systematically validated this concept through strategic platform iterations.

Their V1 release, a straightforward pet simulator, attracted 7 million users, demonstrating that emotional connections remain powerful in today’s digital landscape. Following this achievement, V2 introduced AI-powered pets capable of learning and evolution, gaining 700,000 users within its initial month.

This validated market traction led to the creation of the P-mini—a compact AIoT device that integrates digital pets with environmental monitoring technology. The P-mini o1 incorporates both sensor technology and an interactive AI companion that reacts to environmental conditions, enabling digital pets to exist in contexts beyond traditional screens.

Traditional environmental monitoring faces significant challenges: data sparsity, lack of real-time granularity, and verification difficulties. Government sensors provide only generalized data that misses hyperlocal variations in air quality, noise pollution, and other environmental factors that directly impact daily life.

This creates blind spots in urban environments where pollution levels can vary dramatically between neighborhoods or even streets.

The P-mini addresses these gaps by creating a grassroots network of sensors collecting street-level data. What sets OKZOO apart from conventional DePin networks is its innovative approach to user engagement. Rather than relying solely on financial incentives, the P-mini integrates virtual pets that respond to environmental surroundings, transforming data collection into an interactive, emotional experience.

In-House Manufacturing Capabilities

A key competitive advantage for OKZOO lies in its in-house manufacturing capabilities. Unlike many projects that rely on third-party manufacturers, OKZOO controls its hardware production process, ensuring scalability, quality control, and faster iteration based on user feedback. This vertical integration allows for rapid adaptation to market demands and technological advances.

The ecosystem operates on an incentive model that rewards users for running P-mini devices and contributing environmental data. These contributions establish a comprehensive database powering sophisticated AI applications ranging from customized health guidance to urban planning solutions.

As environmental awareness becomes increasingly important, OKZOO positions itself at the intersection of utility and engagement. By making data collection enjoyable through pet companions, the project creates sustainable user participation while addressing real environmental monitoring needs.

For a market seeking practical applications, OKZOO’s unique positioning across AI, environmental monitoring, and hardware manufacturing presents a compelling vision for addressing real-world challenges while creating engaging user experiences.
