Panasonic’s 2025 product line showcased significant advancements in its full-frame Lumix S system, highlighted by the introduction of the Lumix S1 II and the long-awaited S1R II. In contrast, the company made no announcements regarding its Micro Four Thirds lineup, raising questions about its future commitment to this segment.
The full-frame offerings included the S1 II, featuring a new 44.3-megapixel image sensor capable of shooting at 40 frames per second, advanced AI-powered autofocus, and the ability to record in 8K. This camera builds on the legacy of the original S1, which marked Panasonic’s entry into full-frame photography in February 2019. The S1R II, arriving six years later, addresses previous critiques regarding size and performance.
Chris Niccolls, a well-regarded reviewer in the photography community, noted that “the S1R II is the most well-rounded Panasonic full frame body so far.” Although it lacks a stacked sensor, which limits its performance in fast-paced shooting scenarios, the camera still manages to deliver impressive results.
The S1 II has been praised as a potential leader among video-centric hybrid cameras. Its 24-megapixel partially stacked sensor enhances imaging capabilities significantly, making it a strong competitor against models like the Nikon Z6 III. Niccolls highlighted that this model could be particularly appealing to videographers, thanks to its combination of features and performance.
Alongside the S1 II, Panasonic also released the S1 IIE, which is priced approximately $800 lower than the S1 II. While it retains a 24MP BSI CMOS sensor, it does not feature the advanced technology of the S1 II, resulting in slower performance for both photography and video. With a current market price of $1,000 less than the S1 II, the S1 IIE targets budget-conscious users but may struggle to compete against established alternatives.
The L-Mount Alliance continues to benefit Panasonic users, allowing access to a wide range of high-quality lenses from partners like Sigma and Leica. However, Panasonic’s lens releases in 2025 were limited to just two new offerings. One notable addition is the Lumix S 24-60mm f/2.8, a compact zoom lens priced at $899, catering to those seeking versatility without the bulk.
This year’s lack of new products in the Micro Four Thirds category has drawn criticism. Panasonic has increasingly focused on its full-frame lineup, leading to speculation about the future of its Micro Four Thirds system. As noted, “the writing for Panasonic’s Micro Four Thirds ambitions… is bold and surrounded by flashing lights.” Many enthusiasts continue to value the Micro Four Thirds system, yet its future looks uncertain with no new releases announced in 2025.
Despite the challenges faced by its Micro Four Thirds offerings, Panasonic’s commitment to the full-frame Lumix S system remains strong. The introduction of the S1 II, S1 IIE, and S1R II provides a range of options suited to various photographers and videographers. The company continues to innovate and adapt, ensuring its presence in a competitive market. As the industry evolves, the direction of Panasonic’s product strategy will be closely watched by both consumers and professionals alike.
