The Pentax SFXn/SF1n is a autofocus 35mm SLR camera introduced in 1989, two years after the SFX (SFI).
It uses a electronic vertical traveling metal focal plane shutter with speeds from 30 to 1/4000 of a second. Slower shutter speeds less than 1/30 of a sec has to be used in manual mode. Flash sync is at 1/125 of a sec.
Exposure modes include Programed AE (normal, action, depth), aperture priority, shutter priority and metered manual modes. The meter is a TTL center weighted type with a range of 1 to 20 EV at (ASA 100, 50mm f/1.4), and can be set for DX-coded film speeds from 25 to 5000 ISO and manual speeds of 6 to 6400 in 1/3 stops. The motorized film transport is able to travel at up to 2.2 fps. It can be powered by a 2CR5 battery or by four AA batteries with the optional grip.
