Canon has today announced its new Canon RF 100-300mm F2.8L IS USM telephoto lens, promising a long zoom range with a wide f/2.8 aperture.
While you may be familiar with Canon's current lineup of long prime lenses like the Canon EF 300mm f/2.8L USM IS, or short telephoto zooms, such as Canon's RF 70-200mm f/2.8L IS USM, this new super-tele optic marks a new generation of powerful zooms.
The RF 100-300mm aims to provide incredible telephoto reach with a versatile zoom range, constant wide f/2.8 maximum aperture and the outstanding image quality you’d expect to see from a prime lens (a lens with a fixed focal length and no zoom). The flexible zoom range and wide constant aperture of f/2.8 throughout the entire zoom makes the Canon RF 100-300mm F2.8L IS USM an ideal choice for sports, wildlife, and reportage photography.
The fast maximum f/2.8 aperture will also help allow in lots of light so you can shoot at faster shutter speeds without having to raise the ISO value higher, which can degrade image quality and introduce digital noise. This, paired with 5.5 stops of Optical Image Stabilization (increasing to 6 stops with an IBIS body) should make it ideal for fast subjects in low light, and opens the door to potentially capturing stills or video handheld.

Tipping the scales at 2.6kg, the new Canon telephoto is only 190g heavier than the fixed focal length Canon EF 300mm f/2.8L IS II USM, yet boasts the incredibly useful 3x optical zoom. In addition, it features 5.5 stops of Optical Image Stabilization and a Dual Nano USM motor, which Canon claims delivers a silent and blisteringly fast AF operation.
It's also Canon's first professional RF super telephoto lens to feature a control ring and also boasts a new customizable L.FN button for greater manual control.
As one of Canon’s top-flight L-Series lenses, you can expect dust and weather sealing to protect against the elements in harsh environments, making it a reliable optic for professionals. The aperture is made up of nine circular blades which Canon says will create beautiful bokeh. It also features a heat shield coating for consistent performance in high temperatures.
Also on the spec sheet is one Fluorite lens and four UD (Ultra-low dispersion) lenses which Canon claims will correct chromatic aberration and deliver incredibly sharp images with little color blurring. It also boasts a molded glass aspheric lens designed to ensure high resolution from the center to the edge of the image. We can't wait to get our hands on it and give it a thorough test to see if it lives up to its big claims.
The new telephoto is also fully compatible with Canon RF extenders. Attaching the RF 1.4x Extender will effectively turn the optic into a 140-420mm f/4 lens, and a 200-600mm f/5.6 lens when paired with a Canon RF 2x Extender.
The lens has a retail price of $9,499/£11,499.99/AU$26,999 with sales slated to start on May 19. There will undoubtedly be lots of immediate demand for this lens - so expect we'd expect you may well need to get on the waiting list behind hundreds of professional sports photographers and news agencies if you want this monster!
