One of the big advantage of the Canon 7D vs the 5D is the various frame rate you can shoot with. While for most people it means shooting at 24p to give their clip a more filmic look, shooting at 50 or 60p enable nice slow motions which in turn add to the creative aspect of a clip.

Here is a nice example of what the 7D is able to do.

Notes: the video submitter is not the person who shot it. The original video comes from this review fromRob Galbraith.

Contrary to the 5D Mark II who is stuck at a 30 fps, 7D owners have a nice array of frame rate to pick from according to their needs. The optimal shutter speed is in direct relationship with the selected frame rate. Consult the chart to select the best shutter speed according to the desired frame rate.

• 24p: 1/50
• 30p: 1/60
• 50p: 1/100
• 60p: 1/125
