EF 24-105mm f/4L IS II USM

- New-generation Professional Full-frame f/4 Standard Zoom Lens with Improved Image Quality
- Newly developed 17 elements in 12 groups design with 4.4x zoom power that covers the most frequently-used focal-length from wide-angle to mid-telephoto.
- Use of 1 large-diameter Glass-molded (GMo) double-surface aspherical lens element and 3 Glass-molded (GMo) aspherical lens elements. Image quality is substantially improved by reducing distortion, curvature of field and astigmatism significantly and improving the peripheral brightness
- Incorporation of Air Sphere Coating (ASC) which offers excellent anti-reflection performance to reduce ghosting and flare
- 10-blade circular aperture produces beautiful out-of-focus image
- 0.45m minimum focusing distance with 0.24x maximum magnification (at 105mm)
- Optical image-stabilizer unit offers shake compensation up to 4-stop¹ shutter speed and automatically detects normal shooting and panning for optimized compensation
- Inner focusing design with the Ring-type USM supports low-speed driving to provide high-speed, silent and smooth AF during photo and video shooting
- Lens structure with improved zoom durability and resistance to shock and vibration to meet the demand of professional users
- Fluorine coating on foremost and rearmost lens surfaces makes lens cleaning easier
- Dust and water resistance design² to enable shooting in harsh conditions 
- New zoom ring lock to lock the zoom position at wide end
- Petal-type Lens Hood EW-83M and Lens Case LP1219 are included

A Flexible and High-Quality Everyday Professional Lens with ASC and Superior Optics that Promise Sharp and Detailed Images over the Entire Zoom Range
Infused with Canon’s superior L-series optical technologies, EF 24-105mm f/4L IS II USM professional full-frame standard zoom lens adopts a newly developed 17 elements in 12 groups optical design with 4.4x zoom power that covers the most frequently used focal length from wide-angle to mid-telephoto, and everywhere in-between. This compact, lightweight and all-purpose lens enables professional users to travel light while being able to capture diverse scenes and subjects flexibility in high-quality images with excellent sharpness and details.

The lens uses 1 large-diameter Glass-molded (GMo) double-surface aspherical lens element and 3 Glass-molded (GMo) aspherical lens elements to significantly reduce various types of lens aberrations throughout the zoom range, including image distortion, curvature of field and astigmatism, while also improving the peripheral brightness to achieve high-quality images with high levels of sharpness and detail across the frame. Furthermore, the incorporation of ASC (Air Sphere Coating) which offers excellent anti-reflection performance particularly with respect to incident light that enters lens vertically can guarantee significant suppression of ghosting and flare at a level not possible with traditional coating. The bundled petal-type Lens Hood EW-83M can be used to further reduce flare during shooting.

Advanced 4-Stop1 Image Stabilizer with Fast and Accurate AF for Responsive Performance and Professional Operability
EF 24-105mm f/4L IS II USM features an optical Image Stabilizer that offers shake compensation up to 4-stop1 shutter speed and can automatically detect normal shooting and panning for optimized compensation. This helps ensure high-quality photos and movies with exceptional clarity in many different scenarios, such as handheld shooting at night or tele-end, indoor shooting without flash, as well as the use of slow shutter speed in dim environment.

In addition, the lens adopts an inner focusing design with ring-type USM that supports low-speed driving to provide high-speed, silent and smooth AF during photo and video shooting, facilitating the capture of sharp subjects with responsive shooting. It also features a 10-blade circular aperture for the first time among EF Lens to produce beautiful out-of-focus effect for stunning portrait and movie results. With a minimum focusing distance of 0.45m and 0.24x maximum magnification (at 105mm), the lens realizes greater flexibility to capture small subjects in close range with intricate details revealed in exceptional clarity.

Improved Lens Durability and Reliability for Easy Shooting in Diverse Scenes and Outdoor Environment
To cope with the demands of professional users, EF 24-105mm f/4L IS II USM features an improved lens structure that brings higher zoom durability, shock and vibration resistance to the lens barrel. A new zoom ring lock is also added to lock the zoom position at 24mm wide end to prevent damage to the lens due to accidental extension. In addition, a fluorine coating is applied to the foremost and rearmost lens surfaces to minimize the amount of dust, dirt and fingerprints adhering to the lens, making cleaning easier for superior image quality. The lens also features dust and water resistance design2 to enable shooting even under adverse weather conditions.
