Fast Max shutter speed: 1/4000s Leica M10'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.
Good Low Light ISO A good high ISO performance is very important in sports photography in order to have a fast shutter speed.
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.
Optical Built-in Viewfinder During a sports shoot, using a viewfinder allows the photographer to stabilize the camera and reduce the camera shake since it is closer to the body. Besides, it comes handy where LCD screens are very hard to read under bright sunlight.
Average Continuous Shooting: 5.0fps In the world of sports photography, faster is always better.
Average Ergonomics&Handling although not as good as a DSLR body, Leica M10 is good enough for most conditions.
Environmental Sealings 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.
Poor Battery Life: 210 shots In most sports events, you shoot at high speed for a long time and this drains the battery pretty quick. With a battery life of only 210 shots per charge, you may need to change batteries very frequently in the middle of an event.
No Image Stabilization Due to the lack of sensor based Image stabilization, Leica M10 users have to rely on lenses with optical IS in order to maximize the sharpness of their sports photography photos. Currently there are native Leica M mount lenses with Image Stabilization for Leica M10.
