Three APS SLR systems were released as:
* [[Canon EOS IX]] (EOS IX and IX Lite)<ref>{{cite magazine |url=https://books.google.com/books?id=_lM3mdMJNHIC&pg=PA40 |title=And here they come ... |date=October 1996 |magazine=Popular Photography |pages=40;88 |access-date=14 October 2024}}</ref><ref>{{cite magazine |url=https://books.google.com/books?id=yNijOBJattoC&pg=PA138 |title=Canon EOS IX Lite |date=December 1999 |magazine=Popular Photography |page=138 |access-date=14 October 2024}}</ref>

* [[Nikon Pronea]] (6i/600i and S) with [[Nikon F mount#IX-Nikkor zooms|''IX-Nikkor'' lenses]]<ref name=PopPhoto-9612/><ref name=PopPhoto-9904/>

In addition to these interchangeable-lens models, Olympus released the Centurion, a [[Zoom-lens reflex camera]] (ZLR), similar to an SLR, but fitted with a fixed zoom lens (25~100&nbsp;mm {{f/|4.5~5.6}}). Fujifilm also sold a rebranded version of the Centurion as the Endeavor 4000SL.<ref>{{cite magazine |url=https://books.google.com/books?id=IZdHOG7zepoC&pg=PA115 |title=Top APS point-and-shoots compared |first=Dan |last=Richards |date=December 1996 |magazine=Popular Photography |pages=114–116 |access-date=14 October 2024}}</ref><ref>{{cite magazine |url=https://books.google.com/books?id=AU_di09SdbkC&pg=PA90 |title=Field Test: ZLR meets APS |first=Russell |last=Hart |date=September–October 1997 |magazine=American Photo |page=90 |access-date=14 October 2024}}</ref> Before the system was released, [[Herbert Keppler]] expressed doubt about the potential market for APS SLRs, as both professional and amateur photographers would be constrained by the format's limitations, but thought the reduced size could appeal for niche uses such as photographers who want a more flexible lightweight travel option than a point-and-shoot.<ref name=PopPhoto-9504/>{{rp|22}} APS SLR cameras were not particularly successful; they were too expensive for the high-end amateur market when they first appeared, and professional photographers continued to use 35&nbsp;mm cameras, which offered a wider choice of films, greater image quality and resolution.

Of these the Canon EOS IX and the Nikon Pronea SLRs could use existing 35&nbsp;mm SLR lenses with [[Canon EF mount|Canon EF]] and [[Nikon F mount]], respectively, whereas Minolta opted to create a new lens mount which later was shared with the [[Minolta Dimâge RD 3000]], an early digital SLR (DSLR). Using existing lenses meant the field of view was reduced by around 1.6×, but had the advantage of a larger lens selection. Creating a new lens system on the other hand gave the possibility of creating smaller and lighter lenses as they had a smaller [[image circle]] to cover.

Concurrently with their APS SLR film cameras, Canon, Minolta, and Nikon released lenses specifically intended for use on APS film cameras; the APS-specific lenses have shorter focal lengths to compensate for the reduced image size. Canon's lenses, which included the [[Canon EF 24-85mm lens|EF 24-85mm]],<ref>{{cite web |url=https://global.canon/en/c-museum/product/ef337.html |title=EF 24-85mm f/3.5-4.5 USM |website=Canon Camera Museum |access-date=24 October 2024}}</ref> [[Canon EF 22-55mm lens|EF 22-55mm]],<ref>{{cite web |url=https://global.canon/en/c-museum/product/ef344.html |title=EF 22-55mm f/4-5.6 USM |website=Canon Camera Museum |access-date=24 October 2024}}</ref> and [[Canon EF 55-200mm lens|EF 55-200mm]] lenses,<ref>{{cite web |url=https://global.canon/en/c-museum/product/ef343.html |title=EF 55-200mm f/4.5-5.6 USM |website=Canon Camera Museum |access-date=24 October 2024}}</ref> were fully functional with 35&nbsp;mm EOS SLRs; at least one (24–85mm) was available in silver finish to match the EOS IX camera.<ref name=EOS-IX/>

Minolta released eight lenses for the Vectis V mount, with five zooms covering a range from 22 to 240&nbsp;mm and three prime lenses at 17, 50 (macro), and 400 ([[catadioptric]])&nbsp;mm focal lengths.<ref>{{cite web |url=http://www.minoltausa.com:80/consumer/accessories/lenses/vectis/index.asp |title=Vectis Lenses |publisher=Minolta USA |archive-url=https://web.archive.org/web/19991012221651/http://www.minoltausa.com:80/consumer/accessories/lenses/vectis/index.asp |archive-date=October 12, 1999 |url-status=dead}}</ref> An adapter was available to use 35&nbsp;mm A-mount (Alpha / Dynax / Maxxum) lenses, with limited functionality.<ref>{{cite magazine |url=https://books.google.com/books?id=yNijOBJattoC&pg=PA133 |title=Minolta Vectis S-1 |date=December 1999 |magazine=Popular Photography |page=138 |access-date=14 October 2024}}</ref>

To accompany the Pronea SLRs, Nikon released six [[Nikon F-mount#IX-Nikkor zooms|''IX-Nikkor'' zoom lenses]], all designed by Haruo Sato, which were lighter and had a smaller image circle, similar in concept to the later [[Nikon DX]] format lenses released with the company's DSLRs, starting in 2004. The Nikon IX series of lenses were not compatible with the existing line of Nikon 35&nbsp;mm SLRs; as they were designed with a smaller image circle and had a shorter back-focus, the rear elements, protruding into the body, would foul the mirror.<ref name=Nikkor75>{{cite web |url=https://imaging.nikon.com/imaging/information/story/0075/ |title=NIKKOR - The Thousand and One Nights No. 75: An exciting new photo system that changed the times!
