The Rokinon Reflex 300mm f/6.3 ED UMC CS Lens (Black) is a mirror lens designed specifically for use on Fujifilm x mirrorless cameras. The lens' Cassegrain design enables it to achieve a 450mm 35mm-equivalent focal length perspective within a compact and lightweight lens design that is significantly smaller than a traditional 300mm lens. It features a fixed f/6.3 aperture and utilizes manual focus operation for focusing as closely as 2.95'. One extra-low dispersion element and the inherent mirror construction of the lens work to eliminate chromatic aberrations while providing notable image sharpness and clarity. Furthermore, the UMC (Ultra Multi Coated) coating has been applied to reduce surface reflections, lens flare and ghosting while also contributing to improved overall contrast.
- CAPTURE DISTANT SUBJECTS: The 300mm focal length (450mm equivalent) brings far-off subjects into clear view, ideal for wildlife, sports, and surveillance photography with your Fujifilm X camera.
- UNIQUE DONUT BOKEH: Achieve distinctive out-of-focus areas with the reflex design, creating eye-catching backgrounds that make your subject stand out, adding artistic flair to your images.
- COMPACT AND LIGHTWEIGHT: At just 11.2 oz, this lens is easy to carry, making it perfect for on-the-go shooting without sacrificing telephoto reach, ensuring comfort during extended use.
- SUPERIOR IMAGE QUALITY: Experience enhanced clarity and reduced chromatic aberration thanks to the ED (extra-low dispersion) lens element, delivering sharp, vibrant images with accurate colors.
- SMOOTH MANUAL FOCUS: The precise manual focus allows for fine-tuned control over your images, ensuring sharp focus and creative flexibility, especially in challenging shooting conditions.

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.

As part of the EOS R System, it’s nice and compact thanks to its RF mount so you can shoot – and get a great shot – anywhere and anytime. Size isn’t all though. As a fixed focal length lens, it lets you be creative with composition and can be used for a wide range of scenes from snapshots to portraits, landscapes to low-light situations and more. Those images will stand out, too, just like you intend whether on social media, or when sharing or printing, thanks to impressive optical features like a PMo aspherical lens to suppress aberrations, Super Spectra coating to reduce flaring and ghosting, and a large f/1.8 aperture for low-light shooting and beautiful bokeh. Pick it up and use it one time and you’ll see for yourself, and you won’t be able to leave the house without it.
