It appears that Canon may be looking to expand its current lineup of non-L-series macro lenses for budget-conscious RF-mount shooters.
According to a new patent (publication number: 2026-155997) published by the Japan Patent Office on October 6, the company has at least devised a 90mm f/2.8, 100mm f/2.8, 130mm f/2.8, and 180mm f/4.0 prime lens featuring a distinct optical design from the company’s current L-series (Luxury) macro lenses, but that would still achieve life-size subject reproduction.
Currently, photographers navigating Canon’s full-frame mirrorless lineup face a divide in macro options. The accessible RF 85mm f/2 Macro IS STM offers everyday shooting but tops out at 1:2 (0.5x) magnification.
And the flagship RF 100mm f/2.8L Macro IS USM delivers sharp performance and 1.4x reproduction, but carries a steep price tag and is on the bulky side.
While there’s no saying which budget Canon could truly be gearing these patented designs toward, it would make sense if the lenses were affordable, lightweight, non-L primes capable of true 1:1 life-size reproduction without the weight or cost of L-series glass.
And according to the patent, Canon could be trying to solve this size and cost challenge with a nifty optical formula.
Instead of extending the front barrel during close focusing, the system contains a five-group structure with two counter-moving internal focus groups to achieve 1:1 magnification while suppressing focus breathing.
What’s more, a negative rear element group shortens the overall barrel length, while a simplified single-element front group comprising low-dispersion glass, in theory, would keep chromatic aberrations in check without adding unnecessary weight.
While patent filings never guarantee production, this latest publication does make it seem likely that Canon is actively developing 1:1 magnification lens offerings for its mid-range RF lineup.
