    Digital cameras are generally equipped with buffer memory. The image data received by the image sensor is processed by the image processing engine, stored in the buffer memory, and then written to the recording media (memory card). If the writing to the recording media is slow, the time that data is stored in the buffer memory will be longer. If you take high-speed continuous shots and the image data is stored in the buffer memory, you will not be able to take continuous shots. There are two ways to solve this problem. One is to increase the capacity of the buffer memory. This was often done in the heyday of digital SLRs. However, since buffer memory is expensive, it is not easy to increase the capacity, so it is necessary to increase the writing speed of the recording media, which is the second method. If you can write to the recording media at high speed, the data stored in the buffer memory will gradually decrease, achieving what is called "buffer release." When that happens, it will be possible to accumulate image data in the buffer memory again. For this reason, high-speed recording media is necessary, and this is why I personally hope that CFexpress Type B will become more widespread. However, many users invest in cameras but do not invest much in recording media unless they are professionals. This is the same situation as when many users invested in cameras but not tripods in the past. Professionals invest in recording media because it's their job, and buy recording media that is as fast and stable as possible. Recently, professional-grade digital products seem to have a good reputation. In any case, I'm looking forward to the widespread use of high-speed recording media. If that happens, the price will naturally go down.

    JPEG taken straight out. Taken in August 2021. I had just bought this camera at the time, and it doesn't have the dust-proof and water-resistant structure that I liked because of its small size and light weight, but I haven't been using it that much recently, so it's enough. The recording media is also single-slot, but this is not a problem because I'm not a heavy user. Olympus OM-DE-M5 MarkIII, M 75-300mm F4.8-6.7II, aperture F8, 1/500 seconds, AWB, ISO auto.
