Launched in 1998, the Pronea S is Nikon’s second and last APS SLR. Nikon rapidly lost interest in the APS format, and refocused its R&D (and sales) efforts on the more promising Coolpix digital cameras. With its smaller image format and lenses, the Pronea can be considered a remote ancestor of the vastly more successful Nikon D40.

Apart from the fact it’s using APS film instead of more conventional 135 (24x36mm) film, there is nothing really remarkable about the Pronea S. Its characteristics are aligned on the other mid-level amateur cameras of its time.

It benefits from the advantages brought by the APS format (smaller size than 24×36 cameras, choice of three aspect ratios for the prints) but it also suffers from all the limitations that ultimately caused the demise of the APS format.

In a typical Nikon fashion, the Pronea S preserves some form of compatibility with the large family of Nikkor F lenses: in fact, modern AF and AF-S lenses work perfectly on a Pronea. However the IX-Nikkor lenses, designed specifically for the Pronea and its smaller APS format are absolutely incompatible with the rest of the Nikon bodies: the back of the IX lenses protrudes so far in the reflex chamber that it would be on the trajectory of the reflex mirror of a 24×36 SLR.

The resale value of the Nikon Pronea S is very limited. Mint (if not new) cameras and lenses can still be found, and they generally sell for a few dozens of dollars. They can be collected as curiosities, but their usage value is limited: Kodak and Fuji may cease manufacturing APS film rapidly, and the IX-Nikkor lenses are absolutely incompatible with any “normal” Nikon body.

APS SLR cameras are smaller than a comparable 24×36 autofocus SLR with a built-in flash, but the Pronea S is larger than an older SLR such as the Olympus OM-1
The choice of films was already very limited when the format was supposed to be the next big thing: practically, color print film from Kodak and Fuji in 100, 200 and 400 ISO declinations was the only thing you could get. Now that the format is near extinct, only 200 ISO film is available.
Color slide and black and white film were never widely available, if available at all.
Compared to a 24×36 image, an APS image is 56% smaller. APS requires higher enlargement ratios, which makes film grain more visible.
The film loading mechanism of APS cameras is fragile. The film can stay trapped in the camera if one of the little plastic parts holding the cartridge in place breaks.

Minolta Vectis S-1

The Nikon FA is the last major manual focus SLR launched by Nikon. An evolution of the FM2 and FE2 cameras, it shares with the latter most of its body shell, a very fast shutter (up to 1/4000sec., 1/250sec. flash synchro speed) and a TTL flash metering mechanism. It finally catches up with Canon’s A1 and offers the same four automatic exposure modes (aperture and shutter priority, program and semi-auto).

Its “Automatic Multipoint Metering” (AMP) – a world premiere – is its real claim to fame. Better known under names such as “matrix”, “evaluative” or “multi-segmented” metering, it is now the default metering system of every dSLR in production.

Launched in 1983, this conservatively styled camera with very conventional ergonomics had a relatively short sales career. It was made obsolete in 1985 when Minolta took the market by storm with its first autofocus SLR, the 7000 (Maxxum 7000 in the US). Minolta’s competitors, Nikon included, spent the best part of the following three years trying to catch up. The FA stayed on Nikon’s catalog until 1988, and was not replaced. Its semi-automatic sibling, the FM2n would be sold until 2001, when the FM3a, a sort of combination of the best characteristics of the FM2 and the FE2, was launched.

An impressive (and heavy) camera: the Nikon FA with the MD-15 motor drive.

The metering system

Until the FA was launched, most of the cameras only offered some form of center weighted metering: the exposure sensor evaluated the luminosity of the whole scene, and because the sky is typically in the upper third of the frame, and the main subject of the picture in the center, it was designed to give more importance to the portion of the picture located at the center of the lower part of the frame.

It worked for most of the cases. If the subject was back-lit and not centered, the photographer had to determine the exposure with the subject at the center of the frame, memorize the exposure settings, and move the camera to compose the desired picture.

Some high end cameras also had a second exposure metering system, which evaluated the luminosity of a much narrower portion of the scene, almost a spot in the middle of the viewfinder. But spot metering and exposure memorization are not always easy to use , and are far from being idiot proof. The engineers at Nikon were pretty sure that with the newly unleashed power of integrated circuits, they could develop a new approach.
