The EF 24–105mm f4/L IS II USM’s new optical composition includes 17 elements in 12 groups, including 4 glass-molded (GMo) aspherical lenses on 5 surfaces for excellent overall resolving power. These improvements help increase peripheral brightness for better edge-to-edge results with reduced distortions, delivering still photos and video of great clarity and resolution.
Offering coverage from 24mm wide-angle to 105mm mid-telephoto, the EF 24–105mm f/4L IS II USM is a true walk-around lens that can be used for any number of shooting scenarios. From landscapes and portraits to snapshots and videos of breaking news, and anything else that catches the photographer’s or filmmaker’s eye, the EF 24–105mm f/4L IS II USM range is highly adaptable. You can spend less time changing lenses and more time taking pictures or recording video.
EF 24–105mm f/4L IS II USM features Air Sphere Coatings (ASC) on its lens elements to help combat flare, ghosting and reflections, and deliver clean images with reduced aberrations from reflected light. Designed to significantly reduce distortions, this technology puts an ultra-low refractive layer on the lens element. This layer works with the EF 24–105mm f/4L IS II USM’s overall optical formula to help deliver a clean image to the camera’s sensor, which can decrease the need for post-production.
Thanks to its 10-blade, circular aperture, the EF 24–105mm f/4L IS II USM is capable of gorgeous, evocative out-of-focus areas and soft backgrounds throughout its zoom range. By delivering an incredible level of control over background blur, it helps you define the mood of your image, creating impactful photos and videos.
To help maintain a clean lens, even after multiple lens changes in sub-optimal conditions, the EF 24–105mm f/4L IS II USM has a specially designed non-stick fluorine coating on its front and rear surfaces. This fluorine coating helps prevent dust, water, oil and other surface residue like fingerprints from sticking to the lens, resulting in quick and easy wiping, without the use of solvents.
Befitting an L-series lens, the EF 24–105mm f/4L IS II USM is built to endure photography and moviemaking in even the harshest conditions. It features a dust- and water-resistant construction on the switch panel, the zoom and focus rings, and on the lens mount, helping to prevent dust and moisture from interfering with operation.
The EF 24–105mm f/4L IS II USM is engineered to provide fast, accurate operation for efficient performance across the board. It features a high-performance control CPU that drives Canon’s quick inner focusing with ring USM for quick starts and stops. Plus, it’s programmed with optimized AF algorithms that help achieve fast, accurate focus and maintain it consistently.
The EF 24–105mm f/4L IS II USM offers complete manual control, even when AF is engaged, with a simple twist of the lens’s focus ring. Additionally, full-time manual focus means it’s easy to achieve and maintain focus manually, which can be especially handy when shooting video or composing still images on an SLR’s screen.
