Sí, es cierto. Baja de 14bits a 12bits y por lo tanto menos rango dinámico.

Frame Rate, Buffer Depth, Shutter
I'm excited and cringing at the same time. The Canon EOS R5 can capture up to 12 fps with the mechanical shutter. If 12 fps is still not fast enough, select the full electronic shutter to enable completely silent shooting at up to 20 fps with full autofocus and autoexposure functionality. Sometimes the difference between an average image and a great one is separated by milliseconds, and I'm excited that this camera delivers 45 MP images with the speed necessary to catch the perfect peak action moment. Daunting is selecting the best images from a shoot involving significant use of the 12 or 20 fps capability.
Today, maximum frame rate determination is complicated by many variables. The 12 and 20 fps numbers are achieved when using the High-speed Continuous "+" Shooting mode vs. no "+". I've been trained to expect significant downsides to any speed rating with a "+" at the end, but have been so impressed with this camera's performance that I haven't yet selected the reduced speed. The non-plus mode reaches up to 8 fps. Many other factors can affect the maximum continuous frame rate, including the lens model used (see page 452 and 896 in the owner's manual along with the updated Canon Malaysia list here). Note that RAW and C-RAW have 14-bit A/D conversion with mechanical and electronic 1st curtain shutter, 13-bit in H+ mode, and 12-bit A/D conversion in H+ mode with the full electronic shutter.
