Fast Max shutter speed: 1/4000s
Canon SX420 IS'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. Image Stabilization
Image stabilization reduces the effects of camera shake at long focal lengths thus ensuring sharper photos during sports photography. 1008 mm Tele Lens
1008 mm reach lens will be adequate in most sports events.
although not as good as a DSLR body, Canon SX420 IS is good enough for most conditions.
Slow Continuous Shooting: 0.5fps
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. 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: 195 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 195 shots per charge, you may need to change batteries very frequently in the middle of an event. No Manual Exposure Mode
Even though modern digital cameras features advanced algorithms to calculate the right exposure, they still may fail some difficult conditions. Lack of manual exposure mode in these conditions means lot of shadow and highlight clipping. No 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. 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 External Flash Shoe
When shooting indoor sports or outdoor sports at low light, an external flash may become very helpful. Slow Lens at Tele: f6.60
You will have hard time getting fast enough shutter speeds with a lens that is slow at tele. No 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.
