yeah i first misread the sensor information.
i always thought they will use the latest (best) APS-C sensor for the M2.
why only 4.6 FPS?
other mirrorless cameras have much faster burst rates.
in fact the burst rates are one thing that i really like about mirroless cameras.
With mirrorless, you don't really need more than 2-3fps since you can't track moving subject anyway.
DPAF can track moving subjects, and well enough for 30fps video!
What is "DPAF"?
Dual Pixel Auto Focus, introduced in the 70D.
