Nikon's last APS SLR, from 1998 — compact IX240 body, F mount for IX-Nikkor and AF Nikkor lenses
The Nikon Pronea S was launched in September 1998 as Nikon's second and last APS single-lens reflex, following the Pronea 600i. It packaged SLR versatility into a compact, rounded body for the Advanced Photo System's IX240 film cartridge, aimed at step-up snapshooters during APS's brief heyday.
It is an autofocus, electronically controlled focal-plane-shutter SLR taking IX240 cartridges with a 16.7x30.2mm frame. The Nikon F lens mount accepts the dedicated IX-Nikkor range as well as standard AF Nikkor lenses, with 3D six-segment matrix metering (EV 2-21 at ISO 200), shutter speeds of 30 to 1/2000 second, program, shutter-priority, aperture-priority and manual modes plus four scene programs, and a built-in Speedlight of guide number 16. The body alone weighs about 325g.
Its small size and light weight make it one of the most compact autofocus SLRs Nikon built, and modern AF and many AF-S Nikkors mount and work, which keeps it more usable than most APS hardware. Note the reverse is not true: IX-Nikkor lenses protrude too deep to fit 35mm F-mount bodies, so a Pronea is the only home for them.
APS film was discontinued in 2011, so only expired stock remains and processing options are limited — many examples now sell for display, for parts, or as inexpensive mounts for IX-Nikkor glass. Check the camera powers up, the film door latches, and the built-in flash charges; with film loaded, confirm the motorised cartridge load and mid-roll functions work, as transport faults are uneconomic to repair.
