Fast Max shutter speed: 1/4000s
Ricoh GR III's 1/4000s shutter speed is fast enough to freeze any almost all sports action and is also helpful when you use a fast lens at largest aperture under bright sunlight. Wireless Connection
It may not be used by everyone but pro sports photographers use Wi-fi to transfer files simultaneously without having to wait to change the memory card. Manual Exposure Mode
Even though modern digital cameras features advanced algorithms to calculate the right exposure, they still may fail some difficult conditions. Manual exposure mode in these conditions helps a lot in order to achieve correct and consistent exposure. Manual Focus Mode
Compact cameras are not great at focusing moving objects especially at low light and your camera may not even fire bacause of not locking the focus, so manual focus mode is very useful at these times. External Flash Shoe
When shooting indoor sports or outdoor sports at low light, an external flash may become very helpful. Image Stabilization
Image stabilization reduces the effects of camera shake at long focal lengths thus ensuring sharper photos during sports photography. RAW shooting capability
RAW files contains much more color information compared to JPEGs, and gives you more room for post processing without significant quality loss. They provide wider dynamic range and option to recover shadow and highlight clipping to some degree.
Most outdoor sports games are held in all-weather, so your camera has to be ready for difficult conditions such as rain and snow. Exposure to dust and water splashes are also very common in sports. Focus Points
In sports photography , you keep continuous autofocus (AFC) mode on for tracking the subject and more focus means better tracking. Not so good Ergonomics&Handling
Ricoh GR III\s compact body is not very ideal for sports photography as it lacks the external dials and knobs to change the camera settings fast and the ergonomics doesn't help you to have the most stable shooting position. 28 mm Tele Lens
28 mm reach will not be adequate in many sports events.
