The camera was quite unusual: shutter speed and aperture was automatically set by the camera (AE mode), with no user interaction possible. This reduced the user's workload to focusing, releasing the shutter and winding the film. Film winding could be further simplified by attaching an "Auto-Winder F" to the camera house.
Most SLR cameras would at this time be fully manual, with an option of using one or more automatic exposure modes. The FP-1 was basically a point-and-shoot camera, like most viewfinder cameras, but with the benefit of TTL metering and exchangeable lenses. A similar camera, for the same entry-level user group, is the later Canon T-50.
The AE mode itself was unusual. The camera operated with only 3 possible apertures, f/2.8, f/5.6 or f/11, and would use shutter speeds from 1/30 to 1/1000 sec. in 1/3 light value steps. A f/1.8 lens would have full light strength in the viewfinder, but at exposure the max. aperture would be f/2.8. An e.g. f/3.5 lens would use f/5.6 as the max aperture during exposure.
The only exposure control the user could exercise was to 'cheat' the camera by deliberately mis-setting the film speed.
The camera handles and performs well, but suffers from a very loud shutter/mirror operation. The battery control can be cheated: with a lithium battery, the battery control lamp can indicate 'OK', but not have enough energy to release the shutter. The camera has a sturdy feel, except for the very flimsy battery compartment cover. Without a winder attached, large amounts of dust can (and will!) enter the camera through the winder socket.
With some third-part optics – some authors specifically name Tamron's Adaptall-II – prolonged use can cause excessive wear on the shutter mechanism.
