The dynamic range is higher, and the overall noise level of the Flex4K is significantly lower than the Flex (2K).

The Flex4K is also super-35mm but with a full resolution of 4096 x 2304 and with 6.75 micron pixels. The Flex (2K) has a maximum resolution of 2560 x 1600 on a super 35mm CMOS sensor. The CineMag IV enables ProRes recording to save space and increase total record time. In both cases, Raw Cine files are transferred from RAM (or recorded directly) at speeds over 800 Mpx/second. They mount in the side camera enclosure of the Flex4K, and are not compatible with the earlier cameras. The CineMag IV is available in 1TB and 2TB memory sizes. The Flex4K uses a new CineMag design, called the Phantom CineMag IV. The Flex (2K) uses the CineMag or CineMag II non-volatile magazines. There are many other differences, which we have tried to capture here: The most obvious difference is the pixel resolution: The original Phantom Flex (aka Flex 2K), has a 2.5K sensor and the Flex4K has a full 4K sensor. What are the main differences between the Phantom Flex and Flex4K?
