APS film Lenses

Advanced Photo System film cameras and Minolta Vectis lenses | 30.2 x 16.7 mm APS-H film gate reference with a 34.51 mm diagonal

APS film, also known as IX240, was a cartridge-based film system introduced in the 1990s to simplify loading, mid-roll handling, and print-format selection. The recorded negative used the full 30.2 x 16.7 mm High Definition frame, while Classic and Panoramic output were print-time crops stored through the system's information exchange metadata. This catalog uses that full APS-H style gate because a lens still has to cover the complete recorded frame, even when the photographer requested a narrower print. The result is wider than digital APS-C but still smaller than the 36 x 24 mm 135 frame.

For lens metadata, this format is mainly important because APS film systems were real optical ecosystems, not just a later digital crop label. Minolta Vectis and other APS cameras used lenses designed around the smaller film gate, which allowed more compact bodies and shorter focal lengths than 35 mm SLR systems. In the catalog, APS film should stay distinct from digital APS-C because the dimensions, aspect ratio, era, and camera-system constraints are different.
