Any camera that has manual settings and a remote shutter release will work for high-speed photography (I shoot with Canon 7D and XS).
Using the correct camera settings is the most difficult step: every camera has a so-called shutter lag, namely the time from pressing the shutter button to taking the photograph. Shutter lag can vary from milliseconds to a few seconds depending on the speed of the auto-focus system, exposure measurements, aperture step-down, and SLR mirror. To achieve precise synchronization, the shutter lag must be minimal and constant, which means taking over some of the camera’s functions:
- Pre-focusing and switching the camera to manual focus
- Pre-measuring the scene and setting the exposure to manual
This brings the shutter lag down to exactly 60 ms on Canon 7D and to 100 ms on Canon XS.
