Great informative video as always thanks you. One important question: What would be the "slowest" sd card for electronic first curtain, that allows for bottomless continuous shooting? Do you need v90 or v60 is enough?
V90 and V60 are *Video* Speed Classes, or more precise according to the SD Card Association: “Speed Class designates *minimum writing performance* to record video.” So totally useless for continuous shooting performance^^ Better do the simple math: Electronic first curtain shutter equals 6 fps in case of the EOS R8. And as a rule of thumb, 1 Megabyte per Megapixel for RAW images. 6 frames/s * 24 MB/frame = 144 MB/s. So if you use the table mentioned in the video [ vturl.de/g/219 ], everything above 150 MB/s should be fine for unlimited continuous shooting with 6 fps.
