Canon RF 100-500mm f/4.5-7.1 L IS USM Lens Summary

The Canon RF 100-500mm f/4.5-7.1 L IS USM is a significant telephoto lens aimed squarely at professionals and enthusiasts, which provides longer reach than many comparable models. This versatile super telephoto focal range is ideal for a number of subjects including action, sports and wildlife photography such as birding, together with creative compressed landscape photography. Stunning full-frame images can be captured even in low light thanks to optical stabilisation which achieves up to 5 EV stops (or 6 stops when mounted on the Canon EOS R5). Autofocus is blisteringly quick with high speed Dual Nano USM. This uses two near silent focus motors which is the same technology employed by the excellent RF 70-200mm.

There are further similarities as the RF 100-500mm has also been housed within an extremely compact 207mm casing and is weather sealed for outdoor use during inclement weather. A number of high quality UD and super UD glass elements ensure brilliant optical quality, sharp details and accurate colours from the 20 elements in 14 groups. Despite packing this optical technology the RF 100-500 only weighs in at 1.53kg. making it eminently portable for the range it provides. Front and rear Florine coatings also create a barrier to dust, smears and oil at either end of the lens. Another benefit for tripod or monopod users is the supplied tripod mount ring F, which enables immediate deployment onto a support system. The aperture range is identical to competitor models throughout focal ranges with a very competent f/5.6 at 400mm through to f/7.1 at 500mm. For photographers who need even greater reach the lens accepts compatible RF Extender 1.4x and 2x RF Extender for up to 1000mm focal range. This places any extremely distant subjects enviably close, whilst maintaining full autofocus and stabilisation functionality.

Our Verdict

Canon’s mirrorless camera system is rapidly expanding and the introduction of the RF 100-500mm f/4.5-7.1 L IS USM is a high quality addition. This lens has broad appeal to professionals and enthusiasts thanks to its’ combination of compact portable form, weather sealing and versatile telephoto reach. Image quality is outstanding earning L-series quality through the use of an advanced optical design with high quality elements. Dual Nano USM focussing has already proven itself as the ideal solution for extremely quick, silent and highly capable subject acquisition. This will appeal to any photographers requiring a reliable AF system for their subjects including fast moving sports and wildlife.

A close focus distance of between 90cm and 1.2m allows for yet more creativity with .33x magnification to capture diverse and pleasing close-up images. Compatibility with Canon’s RF extenders also enables photographers to work at huge focal ranges up to either 700mm with the 1.4x or 1000mm with the 2x. The fact that AF and optical stabilisation will work regardless, cements the RF 100-500 lens as the new goto choice for photographers who need vast telephoto reach with their Canon mirrorless cameras. Handheld photography is possible even during low light thanks to the 5 stop stabilisation system and tripod users benefit from an included tripod mount ring. All of this combines to create a highly compelling proposition for users working in a range of photographic fields.
