1. Control the shutter speed
The majority of EOS cameras have a 'Sports' Special Scene Mode that will automatically set up the camera's exposure and focusing settings for shooting moving subjects. This will give you great results, but you can take more control when you want to get creative, produce a particular effect or adjust for the specific circumstances, such as when you're shooting a fast-moving subject handheld from a distance.
To take direct control of the shutter speed, set your camera to Shutter Priority (or Tv, which stands for Time Value). You can then set the shutter speed by rotating the camera's main dial, or by using the touchscreen that's available on many EOS cameras, including the EOS R50 and EOS R8. Your camera will automatically adjust the aperture to produce a standard exposure. If you want to take full control, switch to Manual mode (M) and you can choose any combination of settings you like.
The fastest shutter speed available varies between models, and also according to which shutter mode you select, where a choice is available – mechanical shutter or electronic shutter. The mechanical shutter on a Canon EOS camera typically goes up to either 1/4000 sec or 1/8000 sec, while the electronic shutter in advanced mirrorless EOS R System models can be much faster – up to 1/64,000 sec in the EOS R3. The longest automatically-set shutter speed is 30 seconds. If you want longer exposures, for example for capturing fireworks or light trail photography, you can select Bulb mode. In this mode, the shutter opens when you press the shutter button and stays open until you press it again.
