OSIRIS-REx OCAMS fields of view compared
OSIRIS-REx took these 3 images of the Moon with its 3 science cameras within about an hour of each other on 25 September 2017. The pictures illustrate the differences in field of view and resolving power among the cameras. SamCam has a 21 degree field of view; MapCam has a 4 degree field of view; and PolyCam has a 0.82 degree field of view.

Here is how the 3 OCAMS fields of view relate to the size of the NavCam field of view.

OSIRIS-REx NavCam field of view compared to OCAMS
OSIRIS-REx's NavCams have a wide field of view (44 by 32 degrees) and large detectors (2592 by 1944 pixels). This is a photo of the Moon taken a few days after OSIRIS-REx's Earth flyby. The squares on the image show the fields of view of the mission's science cameras.
