yes, it is an OV9653 (same as 9650 but lead-free and RoHS)
The info we received from the manufacturer is F2.8, view angle 65deg (I am guessing horizontal).
There are a bunch of datasheets floating around but they are marked confidential so I guess we should not post them here. But some keywords that may be useful are "ov9650 datasheet", "ov9650 implementation guide 1.1" and "ov9650 software application notes 1.03".
