From the editor

Made by Tokina.

Although the Spiratone-branded version is labeled 18mm, it is optically identical to the Tokina 17/3.5. Some copies were labeled 17mm, though.

Notes

Independent-brand lenses were made for 35mm film SLR cameras by companies that competed with the camera manufacturers. Some came from factories that made lenses under their own brand names (Angenieux, Kiron, Sigma, Tamron, Tokina). Many others were national and international marketing organizations (Kalimar, Panagor, Rokunar, Soligor, Starblitz) that bought lenses from anonymous manufacturers. One firm — Vivitar — actually designed its own lenses and accessories, which were then subcontracted to manufacturing firms. Still others were private labels, sold only by specific photo specialty shops (Cambron, Quantaray, Spiratone).
