Canon’s VCM (Voice Coil Motor) prime lens series could expand with an RF 14mm f/2L VCM, marking the first departure from the lineup’s standard f/1.4L aperture. This shift makes optical sense for ultra-wide focal lengths, where maintaining faster apertures becomes increasingly difficult.
Canon has inadvertently revealed two upcoming RF lenses through a feedback form at a recent company event. The leaked lenses are the RF 45mm f/1.2 STM and RF 20-50mm f/4 PZ, both generating significant interest among photographers.
On September 9, 2025, Canon made significant announcements in the realm of professional imaging, unveiling the Cinema EOS C50 camera and the RF 85mm f/1.4L VCM lens. These introductions mark a substantial advancement in Canon’s commitment to providing high-quality tools for both filmmakers and photographers.
Canon is set to announce significant new equipment on September 9, 2025, including the Cinema EOS C50 that will replace the EOS R5 C, alongside two new lenses designed to complement the cinema camera.
Canon appears to be finalizing development of a highly anticipated RF 300-600mm f/4-5.6L IS USM lens, with sources suggesting an announcement could come before year’s end. This variable aperture telephoto zoom has been in development for over a year and represents a significant addition to Canon’s RF mount lineup.
Key Specifications and Features
The lens is expected to maintain f/4 aperture from 300-400mm, transitioning to f/5.6 from 400-600mm. While variable apertures typically concern some photographers, the anticipated size, weight, and cost advantages may make this compromise worthwhile for many users.
Pricing estimates place the lens between $6,499-$6,999 USD, though Canon enthusiasts hope it arrives under $6,000. Teleconverter compatibility remains unclear, but if the lens works with Canon’s 1.4x extender, it would provide an effective 840mm f/8 option for wildlife photography.
Market Positioning
Industry sources previously indicated this lens would “cannibalize” sales of the existing RF 100-500mm f/4.5-7.1L IS USM. The significant price gap between these models means many photographers might save longer to acquire the faster, longer-reaching option.
The RF 300-600mm would complement Canon’s recently announced RF 100-300mm f/2.8L IS USM, creating a comprehensive telephoto system without requiring teleconverters.
Development Timeline
Patent applications have surfaced showing supertelephoto RF designs with variable apertures, though none match this lens exactly. Canon rarely reveals exact optical patents before product announcements, making specific details limited.
With the lens reportedly undergoing final testing, photographers may not wait much longer. Canon appears poised for multiple announcements in coming months, beginning with the Cinema EOS C50 next week. For wildlife and sports photographers seeking extended reach with professional build quality, this lens could prove transformative.
