Even then the entry level full-frame cameras will shoot something like 10 photos per second in RAW which is usually sufficient for sports or motorsports photography. There is a compressed raw mode that's required to enable the fastest capture mode but when you get into more expensive cameras like the Sony A1, it can shoot full resolution (50 megapixel) raw with auto focus at 30 frames per second which is mind blowing. It costs $6,500 vs $2,000 for the A7Iv though so you're definitely paying for it.
