Frequently Asked Questions
Why does the Panasonic Lumix S1 II have two different card slots?
The Lumix S1 II features dual card slots – one CFexpress Type B and one SD UHS-II – to offer versatility and cater to different shooting demands. The CFexpress slot handles the most demanding tasks like 6K and 5.1K open gate video, 4K 120p, and internal ProRes recording, requiring extremely high sustained write speeds. The SD UHS-II slot provides a widely compatible and robust option for high-resolution stills, many 4K video formats, and serves as a great backup or overflow solution.
Can I use older SD cards in the Lumix S1 II’s SD slot?
Yes, you can technically use older SDHC or SDXC cards (UHS-I or non-UHS) in the Lumix S1 II’s SD slot. However, their performance will be severely limited compared to what the camera is capable of, especially for video recording and high-speed burst photography. Using slower cards may lead to the buffer filling quickly, limiting burst shooting, or even dropped frames and recording interruptions during video capture, particularly with higher resolution and bitrate settings. For optimal performance, a UHS-II V90 card is strongly advised.
What is VPG certification, and why is it important for the S1 II?
VPG stands for Video Performance Guarantee, and it’s a certification found on some CFexpress and SD cards (e.g., V90, VPG200, VPG400). This rating guarantees a *minimum sustained write speed* under demanding video recording conditions. For a camera like the S1 II, which records high-bitrate video like 6K RAW, a high VPG rating ensures that the card can continuously write data at the required speed without dropping frames, leading to smooth, uninterrupted footage.
Is it worth investing in a high-capacity CFexpress card for my S1 II?
Absolutely, especially if you plan to utilize the S1 II’s advanced video capabilities or engage in extensive burst photography. The massive file sizes generated by 6K video or high-frame-rate RAW stills can quickly fill up smaller cards. A high-capacity CFexpress card (256GB, 512GB, or more) minimizes the need to swap cards during a shoot, ensuring you don’t miss critical moments and streamlining your workflow. While expensive, it’s a worthwhile investment for professionals.
Do different brands of memory cards perform differently in the Lumix S1 II?
Yes, different brands and even different series within the same brand can perform quite differently. While advertised peak speeds are important, the sustained write speed is often the real differentiator for high-performance cameras like the S1 II, particularly for video. Some users have reported varying thermal performance with certain brands of CFexpress cards in Lumix cameras, so it’s always wise to check reviews and compatibility lists from trusted sources to ensure optimal performance and reliability.
