RF100-400mm F5.6-8 IS USM Lens
Perfect for wildlife, sports, travel and more, the RF100-400mm F5.6-8 IS USM is a compact, lightweight telephoto lens for EOS R Series cameras, offering a versatile zoom range that brings subjects closer with ease. The RF100-400mm F5.6-8 IS USM is similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens, and not only reaches to 400mm, but also has fast Nano USM focusing and up to 6 stops of Coordinated IS when used in combination with an EOS R series camera featuring In-body Image Stabilization, like the EOS R5 and EOS R6, or 5.5 stops with an EOS R/RP camera. Using a single Ultra Low Dispersion lens element towards the front of the lens group corrects chromatic aberration throughout the entire zoom range, making your images look crisp and colorful with minimal color blur. The RF100-400mm F5.6-8 IS USM lens can also accept both the RF1.4x and RF2x tele extenders giving you the effective maximum focal length of 560mm and 800mm respectively. With a control ring that allows for quick setting changes, including shutter speed and aperture, the RF100-400mm F5.6-8 IS USM lens puts quality, convenience and control in your hands.
Features:
Compact, lightweight and high-image quality RF tele zoom lens, with a versatile zoom range of 100-400mm
The travel-friendly size and weight (similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens but a bit lighter) of this lens makes it easier for it to be attached with a camera around your neck while walking around for an extended time and also allows room for more lenses in a camera backpack.
Optical Image Stabilizer with up to 5.5 Stops* of shake correction Because RF lenses are designed specifically for the RF Mount found on EOS R series cameras, the lens and camera combine to share Image Stabilization data, helping to dramatically reduce the effect of camera shake that can occur when working handheld. This applies when capturing both stills and video with up to 5.5 stops of stabilization* for accurate and clear content.
