Take this with a grain of salt, but Canon Rumors suggests a new constant f/4 aperture RF-S zoom lens is on the way. This announcement coincides with the rumored spring release of the EOS R7 Mark II.
A dedicated prime lens for APS-C users has long been a missing piece in the RF-S lineup. Introducing a zoom that locks at f/4 would finally give photographers a lightweight option for video and low-light work without sacrificing image quality.
This constant aperture design is a smart move by Canon, especially if you are looking to pair it with the upcoming R7 Mark II. The RF mount ensures compatibility across your current kit while keeping the profile slim enough for travel.
Compared to the pricier RF L-series optics, an f/4 zoom in this segment should offer better value for money. We expect the pricing to sit somewhere between $500 and $600, making it accessible for hobbyists upgrading from EF-S glass.
