Panasonic Announces the S1II and the S1IIE

Panasonic held a YouTube livestream on May 13, 2025, where new Lumix products were debuted. The event unveiled two full-frame mirrorless cameras—the S1II and S1IIE—new L-mount lens, and firmware for the Lumix S1RII. This account, in a technical and dry style for technical reviews, summarizes the announcements and their relevance to the mirrorless camera industry.

The Lumix S1II and S1IIE are designed for hybrid content creators who need camera and videography equipment. Both feature a 24-megapixel partially stacked CMOS sensor with 4K 60p uncropped video and a wide dynamic range for various lighting situations. The S1II is a do-it-all hybrid camera for applications like portraits and short films. The S1IIE has a barebones design, targeted at customers who desire fewer features but maintain basic performance. Both cameras utilize phase-detection autofocus, an upgrade over the S1 series' contrast-detection. It allows for improved subject tracking for moving subjects in action scenes. These capabilities place the S1II and S1IIE in the mid-to-high-end mirrorless ranks.

Panasonic also unveiled a new L-mount standard zoom lens, a 24-60mm f/2.8, for its L-mount system, which is also common to Leica and Sigma. The lens has a fast f/2.8 aperture to facilitate low-light image capture and depth-of-field control, and it is compatible with the S1II, S1IIE, and other L-mount cameras. The new addition is part of the L-mount lens family.

An upgrade to the firmware of the Lumix S1RII added 8.1K Open Gate recording and ARRI LogC3 support. Reframing in post is offered by Open Gate format, while ARRI LogC3 offers compatibility with professional cinema pipelines. The update is designed to bring the S1RII up to date for video professionals.

The announcement came during a string of tech announcements, making for an active news week. Panasonic's pre-Christmas timing appears aimed at the holiday shopper. The S1II and S1IIE address the requirement for hybrid cameras that can perform well in both still photography and video, and the L-mount lens and S1RII refresh address the requirement for support of the Lumix ecosystem.

The new lenses and cameras focus on hybrid capability, improved autofocus and video performance. The S1RII firmware update targets video consumers. The products position Panasonic in the competitive mirrorless market.

Additional information is found via Panasonic's official Lumix channels. Pre-orders for the S1II and S1IIE are available now, with the S1RII firmware update later in 2025.

Panasonic Introduces New Large-Aperture Standard Zoom Lens:

LUMIX S 24-60mm F2.8 (S-E2460)

Panasonic is pleased to expand its LUMIX lens lineup, with the introduction of the LUMIX S 24-60mm F2.8 (S-E2460), a new large-aperture standard zoom lens bult according to the L-Mount system standard.

This new lens features a large F2.8 aperture throughout its versatile zoom range. Its unique compact and lightweight design enhances mobility, making it an ideal choice for dynamic landscape and architectural photography, at the 24mm wide-angle perspective, as well as for capturing beautifully bokeh-rich portraits at 60mm focal length. The Hybrid Zoom feature (*1), extends the zoom range up to 187mm (*2) for both photos and videos. The generous aperture of F2.8 provides high-resolution performance and exquisite bokeh across the zoom range, offering fast shutter speeds and minimizing subject blur even in low-light conditions.

Through a carefully optimized lens configuration and a minimized filter diameter, the new lens achieves compactness and a light weight of 544g, with a total length of approximately 99.9mm. It also incorporates a recently developed Dual Phase Linear Moto and advanced optical encoder, resulting in high-speed, high-precision AF performance. Versatility is further boosted by an equipped focus button on the lens barrel, facilitating intuitive shooting and allowing customization of preferred features assigned to the button. For the first time in the S series (*4), the LUMIX S 24-60mm F2.8 lens supports control ring assignment (*5). This added feature enables quick access to key settings such as aperture control and exposure compensation through the use of the focus ring as a customizable control ring.

Moreover, it has outstanding video production capabilities, including an advanced optical design and an optimized internal barrel structure that effectively suppress focus breathing. In high-contrast scenes, micro-step aperture control ensures smooth F-stop transitions, preventing abrupt exposure changes. With its wide starting angle at 24mm and broad feature set, it is also an excellent choice for video, offering phenomenal versatility in a single lens.

The LUMIX S 24-60mm F2.8 (S-E2460) Lens will be available starting late June at valued channel partners.
