Canon announces new lightweight wide-angle lens for mirrorless cameras

Canon today announced the RF14-35mm F4 L IS USM lens. The new wide-angle lens is designed for use within the expanding family of EOS R full-frame mirrorless cameras, including the upcoming EOS R3.  The Canon RF 14-35mm F4 L IS USM lens features f/4 aperture, L-Series optical construction — highlighted by three UD-glass elements, and three Aspherical elements — and lens coatings, including Sub-wavelength Structure Coating (SWC) and Air Sphere Coating (ASC). 

Key features

• 77mm screw-in filters
• Compact design — Approximately 1.2 lbs. in weight
• Optical Image Stabilizer with up to 5.5 stopsi of shake correction
• Minimum focusing of 7.9 inches at all focal lengths and a maximum magnification of 0.38x at 35mm zoom setting.
• High speed, smooth and quiet autofocus with Canon’s Nano USM
• Control Ring for direct setting changes of aperture, shutter speed, ISO speed and exposure compensation. 
• Up to 7 stopsⁱⁱ of shake correction when paired with Canon EOS R series cameras that feature In-Body Image Stabilizer (IBIS). 

ⁱⁱ Based on CIPA (Camera & Imaging Products Associations) standards. Testing performed at focal length of 35mm, using the EOS R5 camera.

A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens’ results from center towards the corners.
