Mic CompatibleTally Lamp and Dedicated Selfie Controls

The Nikon Z30 mirrorless camera is designed with today’s content creators in mind who are looking to record and share their everyday adventures. This DX-format camera borrows specs and capabilities from other Z cameras, including Nikon’s renowned image quality and advanced autofocus performance, but sports an all-new design and offers purpose-built handling that prioritizes video and single-shooter productions.

The video specs are focused on online sharing and livestreaming with UHD 4K recording at up to 30p is the top-spec recording format, along with Full HD at 120p for slow-motion playback. The recording limit is more than two hours for those situations where a long continuous take is required, such as when recording performances or events. If using the camera as a webcam, then FHD at up to 60p is possible, or 4K at 30p, and constant power delivery is available through the USB Type-C port.

The Z30 supports a 20.8MP sensor, which suits 4K video recording, as well as benefits any day-to-day photo needs you have, including shooting your promo shots, thumbnails, or even for photographing fast-moving action at up to 11 fps. The large sensor size helps produce imagery with a high degree of clarity and can create blurred backgrounds to highlight your main subject. The sensor and image processing also enable useful low-light performance, with sensitivity up to ISO 25600 for video, or up to ISO 51200 for stills, and digital image stabilization, e-VR, also permits recording in low light by stabilizing any wobbly footage. Additionally, it’s worth pointing out that the Z30 can record time-lapse sequences with in-camera processing and there is a series of in-camera effects and filters for producing ready-to-share footage straight from the camera.

The Nikon Z30 is available as just the camera or can be bundled in a one-lens kit with the NIKKOR Z DX 16-50mm f/3.5-5.6 VR lens, or in a two-lens kit, including the body, 16-50mm lens, and the NIKKOR Z DX 50-250mm f/4.5-6.3 VR lens.

On the optical side of today’s launch, the super-telephoto prime NIKKOR Z 400mm f/4.5 VR S follows in the footsteps of the impressive Z 800mm f/6.3, and Nikon describes it as “the smallest, lightest 400mm” the brand has ever created. Providing a healthy mixture of reach and portability, this lens promises to be an excellent option for nature and wildlife photography, especially when hiking is required, or for handheld sports and action capture.

Key Features

As similar to the Z 800mm f/6.3 as this lens is, one notable distinction is the 400mm f/4.5 does not use a Phase Fresnel (PF) element to achieve its sleek size. Rather, it relies on more “conventional” specialized elements to realize well-controlled imagery while remaining compact. Super ED, ED, and SR (short-wavelength-refractive) glasses are used to control a variety of aberrations and color fringing, and a Nano Crystal Coat is also featured to reduce flare when working in strong lighting.

The new  400mm sacrifices 1.3 stops of light and a built-in teleconverter for a very handy 3.8-lb weight reduction (the 400mm f/4.5 weighs just 2.7 lb) and a useful 6″ reduction in length—the new lens measures 9.2″ long. In more relative sizing terms, this 400mm prime has nearly the same dimensions as Nikon’s Z 70-200mm f/2.8 but still weighs 4 oz less than that. Portability is one of the key assets for this new lens—especially if you’re able to sacrifice a bit of light and depth of field, you end up with this truly portable, hand-holdable super-telephoto. The lens features optical Vibration Reduction, which compensates for up to 5.5 stops of shake on its own or up to 6 stops of shake when paired with a camera’s IBIS system using Synchro VR.

Greater Precision of HER2-Expressing Breast Cancer Treatment with 3D Pathology: New JelloX Research Collaboration

Published

on

By

In the preliminary findings of a study conducted with the National Taiwan University Hospital, over 50% of sample cases were reclassified as HER2-expressing when 3D pathology was applied.

HSINCHU, April 17, 2025 /PRNewswire/ — JelloX Biotech Inc., a Taiwan-based startup at the forefront of cancer pathology, announced the preliminary results of a research collaboration with the National Taiwan University Hospital (NTUH) on breast cancer patients. The study found that JelloX’s 3D pathology technology identified a significantly increased proportion of tumors with HER2-low and HER2-ultralow expression compared to conventional methods, demonstrating this technology’s increased sensitivity and potential as a superior diagnostic tool for HER2 detection in breast cancers.

Contact JelloX at sales@jellox.com to explore partnerships and learn more about the company’s cutting-edge 3D pathology technology.

According to the US National Cancer Institute, breast cancer is the most prevalent form of cancer. However, the difficulty of precisely determining treatment has made the identification of HER2 expression essential. In HER2-low and HER2-ultralow metastatic breast cancer, the novel antibody-drug conjugate (ADC) Trastuzumab deruxtecan (T-DXd) has demonstrated robust efficacy over conventional chemotherapy. Yet considering HER2 spatial heterogeneity, traditional diagnostic methods have shown to be less precise than 3D pathology in detecting the presence of the HER2 protein.

“For the specific challenges posed by metastatic breast cancer and the need to identify predictive biomarkers accurately, the high sampling capacity of 3D pathology holds particular potential,” commented Dr. Yen-Yin Lin, CEO of JelloX. “JelloX Biotech’s Comprehensive HER2 Diagnostic Solution is poised to revolutionize HER2 diagnostics. With a more comprehensive data set on tumor samples, healthcare providers can be empowered to make more precise diagnoses, ensuring that the right patients receive the right treatment at the right time.”

New findings with NTUH on HER2 breast cancer

In JelloX’s research collaboration with NTUH, preliminary findings indicate that more than half of the analyzed cases exhibited diagnostic discrepancies when re-evaluated using the company’s advanced 3D pathology methods. Notably, among patients initially classified as HER2-null by traditional methods, more than 66.7% were reclassified as HER2-expressing (HER2-low or HER2-ultralow) using 3D technology, thereby becoming potentially eligible for T-DXd treatment.

These findings echo the company’s recent results using samples from colorectal and esophageal cancers, demonstrating that 3D pathology may have broader potential across various cancer types.

The full findings will be shared at the Global Breast Cancer Conference in South Korea on April 17. https://gbcc.kr/Main.asp

Implications for breast cancer treatment and drug guidelines

T-DXd has demonstrated significant efficacy in tumors with HER2 expression. However, tumors classified as HER2-null under conventional pathological testing are ineligible for T-DXd treatment. By detecting HER2 more precisely using 3D pathology methods, we can identify more patients eligible for T-DXd therapy.

In addition to cancer patients, JelloX’s 3D pathology technology has the potential to expand possibilities across healthcare stakeholders:

For physicians: This advanced diagnostic tool offers a more comprehensive patient data set and, when integrated with AI, helps reduce physician workloads.For pharmaceutical companies and research institutions: The technology enhances companion diagnostics (CDx) for drug usage and is a valuable tool for new drug development.For healthcare systems: 3D pathology optimizes medical resource allocation and minimizes unnecessary financial and healthcare burdens.

About JelloX Biotech Inc.

Based in Hsinchu, Taiwan, JelloX Biotech Inc. is a startup that focuses on advancing cancer pathology through 3D digital imaging and AI technology.
