A new patent filing has revealed a design for a Canon RF 90mm f/2.8 IS STM macro lens, according to a report from Canon Rumors dated October 6, 2026. The document shows an optical layout that includes image stabilization (IS) and STM focusing motor technology, indicating a lens aimed at both stills and video creators who need close‑up capability.

The report notes that this forthcoming lens would not belong to Canon’s L‑series lineup. That distinction is made because the RF 100mm f/2.8L IS USM macro lens already occupies the premium macro slot in the RF mount family. By positioning the 90mm version as a non‑L offering, Canon appears to be targeting a different price point or feature set while still providing macro performance.

This latest patent resembles an earlier design for a 90mm macro lens that Canon had previously disclosed. The similarity suggests the company is refining a concept it has explored before, possibly incorporating updates to stabilization or focusing mechanisms based on user feedback and technological advances since the first iteration.

For creators, the addition of another RF macro option expands the choices within Canon’s growing RF lens ecosystem. The RF mount already hosts a variety of lenses ranging from ultra‑wide to telephoto, with several macro solutions available for product photography, nature work, and detail‑oriented video work. A 90mm f/2.8 IS STM macro would sit between the existing 100mm L macro and shorter focal length macro lenses, offering a moderate working distance with built‑in stabilization.

While the patent confirms that Canon is actively developing this lens design, the report does not specify a release timeline, pricing, or final specifications. The appearance of the patent, however, signals ongoing investment in the RF macro segment and reinforces Canon’s commitment to providing creators with a diverse set of tools for close‑up imaging.
