SFX / SF1
General Description
The SFX / SF1 was Pentax’s answer to the overwhelming success of the Minolta 7000 auto
focus SLR camera. Like the Minolta 7000 and unlike the much earlier PENTAX ME F, the auto focus motor is
integrated into the camera body. With the SFX / SF1, the new F series auto focus lenses are introduced.
The SFX / SF1 fully supports all older K-, M- and A-series lenses, and the F-series lenses can be used
on all K-mount bodies before and after the SFX / SF1.
The SFX / SF1 was the very first SLR camera offering a built-in flash. The hot-shoe for external flashes now sits on top of the large camera grip, so that internal and external flashes can be used simultaneously.
