Fast Continuous Shooting: 8.0fps In the world of sports photography, faster is always better.
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.
Fast Max shutter speed: 1/25600s Sigma BF's 1/25600s 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.
Anti Flicker feature Many sporting events involve flickering lights that cause unwanted effects on the photos. Anti flicker feature reduces this effect, although generally reduces the maximum continuous shooting speed of the cameras.
Average Ergonomics&Handling although not as good as a DSLR body, Sigma BF is good enough for most conditions.
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: 260 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 260 shots per charge, you may need to change batteries very frequently in the middle of an event.
No Built-in Viewfinder In the lack of a a viewfinder, holding the camera away from the body while using live view is not very stable, especial with heavy camera bodies and lenses. Besides, LCD screens are very hard to read under bright sunlight.
No Image Stabilization Due to the lack of sensor based Image stabilization, Sigma BF 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 L mount lenses with Image Stabilization for Sigma BF.
