Canon RF 100-400mm f/5.6-8 IS USM Telephoto Zoom Lens in Black

The Canon RF 100-400mm f/5.6-8 IS USM is a telephoto zoom lens designed for Canon's RF-mount mirrorless camera system. It provides a versatile focal range from 100mm to 400mm, making it suitable for capturing distant subjects such as wildlife, sports events, and detailed landscapes. The lens incorporates Canon's Optical Image Stabilisation (IS) technology to help minimise camera shake, which is particularly beneficial when shooting handheld at longer focal lengths. Its compact and lightweight design enhances portability for photographers on the move. Key features include a maximum aperture range of f/5.6 to f/8, a stepping motor (STM) for smooth and quiet autofocus operation—ideal for video recording—and a minimum focusing distance of 0.88 metres, allowing for surprisingly close-up shots. The optical construction comprises 12 elements in 9 groups, including one Ultra-low Dispersion (UD) element and one aspherical element to control chromatic aberrations and distortions. A Super Spectra Coating helps to reduce ghosting and flare. The lens includes a lens hood and features a 67mm filter thread for attaching circular polarisers or neutral density filters. This lens is best suited for enthusiast photographers and videographers seeking an affordable and portable telephoto option for their RF-mount camera. Its combination of reach, image stabilisation, and relatively compact form factor makes it a practical choice for travel, outdoor adventures, and situations where carrying heavier professional telephoto lenses is impractical. While the variable aperture becomes slower at the telephoto end, the effective stabilisation system helps maintain image quality in various lighting conditions when used with modern cameras featuring good high-ISO performance.
