Re: Why the EOS-M is such a great camera...

The 18-55mm M lens that you used has a burst rate of 1.7 shots per second.

But an EF lens will offer a burst rate of around 4.5 shots per second. I don't know why this is.

Burst rate is ~4.3 fps for all lenses if the camera is set to one-shot AF.

It drops to 1.7 fps for the 18-55mm EF-M lens and 1.2 fps for the 22mm EF-M lens when using Servo AF.

EF and EF-S lenses retain the 4.3 fps shooting rate even when using Servo AF because the Servo AF is effectively disabled and the camera locks focus on the first shot.
