Cam locked after one recording

[Peter Addor]

I recently purchased a Sony alpha 6600 (I had a DSLR for years). When I press the shutter button, the camera stays locked for 2-3 seconds. Is this the case with mirrorless cameras? My DSLR was immediately ready for a new shot. If I take a picture of a flock of birds, for example, it has long since flown away by the time the camera allows a new picture. That can't be! In continuous shooting mode, the camera is capable of taking photos in quick succession. Why not in single-shot mode?
