Canon RF 100-400mm F5.6-8 IS USM Lens Features In Detail

Advanced Optical Design

The Canon RF 100-400mm F5.6-8 IS USM lens incorporates advanced optics to deliver exceptional sharpness and clarity across its entire 5x zoom range. It includes an aspherical lens element and UD glass that effectively minimises chromatic and spherical aberrations. With Super Spectra Coating, flare and ghosting are also reduced for greater contrast and colour accuracy. Whether shooting at 100mm or 400mm, this lens captures crisp details and vivid results.

5.5-Stop Image Stabilisation

Built-in Optical Image Stabilisation provides up to 5.5 stops of shake correction for incredible handheld performance. This allows photographers to capture sharp images and smooth footage handheld at slow shutter speeds and in low light. The stabilisation also handles movement effectively, enabling clear shots of fast action. Users can handhold the RF 100-400mm lens confidently in a variety of conditions knowing their images will come out sharp.

Lightweight but Durable Design

Despite its impressive reach, the RF 100-400mm F5.6-8 IS USM lens weighs just 635 grams. This lightweight design makes it comfortable for prolonged handheld shooting without fatiguing the user. The lens is constructed using strong yet lightweight materials to produce this portable form factor that travels well. Measuring 6.5 inches when retracted, it takes up minimal space in a camera bag. The lens also features a dust and moisture-resistant construction for use in challenging environments.

Fast, Quiet USM Autofocus

A Nano USM focusing motor drives the quick, near-silent autofocus of this telephoto lens. Users can quietly track subjects such as wildlife without startling them to capture natural behaviours. The autofocus pairs extremely effectively with the EOS R systems Eye AF and Tracking AF ensuring accurate focusing on moving subjects. Focusing is also highly customisable, with both AF and MF modes available.

Control Ring for Convenient Operation

The RF 100-400mm F5.6-8 IS USM lens includes a customisable control ring that is programmable directly through EOS R series camera interfaces. This provides an intuitive way for photographers to adjust key exposure settings without taking their eye off the viewfinder. They can instantly change aperture, shutter speed, ISO and more according to their personal preferences.

Teleconverter Compatible

To further extend the reach of this lens, Canon teleconverters are fully compatible. The drop-in style RF 1.4x and 2x extenders seamlessly integrate autoexposure, autofocus and metadata communication between the lens and camera body. When combined with the teleconverters, impressive focal lengths up to 1600mm are possible with maintained functionality.

Ideal for Distant Subjects

Featuring a powerful super-telephoto zoom range of up to 400mm, the RF 100-400mm F5.6-8 IS USM lens excels at photographing small, distant subjects. This makes it the perfect choice for wildlife, birding, airshows and astrophotography. Users will delight in capturing handheld reach shots of subjects near or far in fine detail.

  • Aviation Photography – 100-400mm flexibility suits airshows, able to tightly crop in on aerobatic planes performing whilst retaining image quality.
  • Astrophotography – Effective stabilisation and 400mm reach make it possible to photographically capture intricate details of lunar craters and celestial bodies.
  • Travel Photography – Lightweight and compact design that conveniently packs in bags for hiking and world exploration, versatile for all opportunities.

What We Think The Canon RF 100-400mm F5.6-8 IS USM lens Review

The Canon RF 100-400mm F5.6-8 IS USM lens hits a sweet spot between price and performance. As a more affordable alternative to high-end super-telephotos, it brings lightweight reach to wildlife, sports and travel photography.

We love the compact, portable form factor. At just 1.45 lbs, it’s easy to pack in your kit bag for a full day of handheld shooting. The weather-resistant design also inspires confidence for hiking and outdoor use. Canon managed to keep size and weight down without compromising on features or optics.

The dual benefit of the built-in stabilisation and Nano USM focus motor stands out. This combination makes it simple to capture tack-sharp action shots with quick, accurate autofocus. Stabilisation further expands creative options for handheld video and low-light photography.

While the maximum f/8 aperture translates to a slight low light limitation, we don’t see it as a deal breaker given the friendly price point. For situations demanding fast glass, primes around 100-400mm provide one solution. Optional extenders also help enhance the 100-400’s capabilities.

For its balance of portability, features, and affordable reach, we consider the RF 100-400mm lens a compelling choice. Wildlife and sports enthusiasts will love bringing small, active subjects crisply into the frame with the versatility this 5x telezoom affords.
