RF14mm F1.4 L VCM

Improved sharpness, especially at the edges and corners. Great reduction in chromatic and other aberrations. Significant reductions in lens flare, in strong back-lit scenes. A total re-design of the 14mm lens brings all these to EOS R-series users. Canon’s L-series optical technologies are showcased here, with multiple types of specialized lens elements, including one Canon’s BR (Blue spectrum Refractive) optics and the first-ever application of a Fluorite lens element in a Canon ultra wide-angle lens. And two distinct types of Canon-developed lens coating technologies — Canon’s Air Sphere Coating (ASC) and Subwavelength Structure Coating (SWC) — are keys to reducing flare and ghosting.

Two stops faster than Canon’s previous EF-mount 14mm F2.8 L II USM lens — and likewise, two stops faster than F2.8 zoom lenses — the RF14mm F2.8 L VCM lens opens new doors to critical still-image and video users. Its ultra-wide coverage makes it ideal for dramatic creative imagery, as well as for subjects ranging from interiors and landscapes to music video productions. And with its maximum F1.4 lens aperture, this lens becomes ideal for low-light work, up to and including starscapes. The combination of such wide-angle coverage with a wide F1.4 lens aperture is an optical mountain for lens designers, but Canon’s engineers have graced the 14mm F1.4 L VCM lens with incredible performance. And that can equal incredible opportunities for visual creators.

A specific design goal of the RF14mm F1.4 VCM lens was superb performance in the challenging environment of starscape photography — where even the slightest aberrations at wide apertures can be immediately noticeable by critical users in finished, high-resolution images. The above-mentioned specialized optics combine for what may be Canon’s finest lens to date for starscape imagery — and a huge improvement in astrophotography image quality, vs. the previous EF 14mm F2.8 L II design.

The RF14mm F1.4 L VCM lens, as the name suggests, is another member of Canon’s VCM lens series. This is truly a hybrid lens series — each VCM lens has consistent length and width*, and consistent placement of manual focus rings. This consistency simplifies lens changes for video users working with rigs or other support devices. And, it features a manually-adjustable Iris Ring, allowing critical video users smooth manual aperture adjustments if desired. Excellent control of “focus breathing” is another big part of the optical design. But to be clear: any of the VCM lenses, including the 14mm F1.4, are spectacular for still-image work, and should never be considered as “video-only” optics.

A relatively recent technology introduction in Canon’s RF lens line, VCM focus drive motors offer superb power and torque, to rapidly move heavier groups of internal focus elements for swift and virtually silent AF performance. These are up to the dual challenges of both extremely quick AF for still-image shooting, but smooth and positive focus transitions during video recording with EOS R-series cameras. And, compared to the ring-type Ultrasonic Motors (USM) used in the previous EF-mount 14mm f/2.8 L lens, the VCM motor design has noticeable benefits in reducing overall lens diameter as well.

A stunning reduction in lens diameter and weight is achieved by the RF14mm F1.4’s optical and mechanical design, vs. the previous EF14mm f/2.8L II lens. A wider maximum aperture normally means an increase in size and weight. But the combination of the overall mirrorless structure and Canon’s innovative designs make this lens lighter and slimmer in diameter than the previous f/2.8 version. Again, the RF14mm lens shares common exterior design and most dimensions with previous RF-mount VCM fixed focal length lenses.

Conveniently located on the side of the lens barrel, one Lens Function Button can be user-customized in the camera’s menu to perform any one of a multitude of potential tasks. For users who desire, it can mean instant access to an important camera setting, feature or focus setting. With an advanced camera like the EOS R6 Mark III, any one of 77 different possible functions (plus totally disabling the Lens Function Button) can be chosen in the camera’s Customize Buttons menu.

Eleven aperture blades in the RF14mm lens’s diaphragm preserve smooth rendering of out-of-focus in video and still images — especially at close focus distances — even when conditions require the aperture to be stopped-down from its maximum F1.4 opening.
