The XA2 is "Program Mode" _only_ with three zone focusing settings. From
its instruction manual:
Lens: 35mm D.Zuiko f/3.5, 4 elements, 4 groups
Shutter: Programmed between-lens shutter
Exposure control: Programmed shutter. Automatic exposure range
2 sec @ f/3.5 to 1/750th sec @ f/14 (EV 2.5 - 17)
It doesn't say anything about how the program steps through combinations of
shutter speed and aperture. It is surprising the shutter is rated to
1/750th! The practical limit on a leaf shutter is about 1/500th. Shutter
speeds faster than 1/500th can have problems with producing an even
exposure across the film plane.
