EF24-105mm f/4L IS II USM

EF24-105mm f/4L IS II USM

This lens is significantly renewed with the adoption of a large-diamiter GMo dual surface aspherical lens, realizing better image quality, less distortion, and improved peripheral illumination compared to its predecessor. For superior overall performance, the latest technological features of the lens include ASC that suppresses occurrence of flare and ghosting, a newly designed IS unit that enhances camera-shake blur compensation, improved durability resulting from a newly designed mechanical structure, and other factors. With its upgraded image quality and operability, this lens is strongly positioned as the new standard lens for full-frame cameras for professional and advanced amateur use.

  • Aspherical lens
  • ASC
  • Fluorine coating

This lens newly employs ASC (Air Sphere Coating) in addition to optimized coating. This suppresses ghosting and flare that conventional vapor-deposition coatings cannot prevent.

Enhanced IS performance
A newly designed IS unit and control algorithm improve camera-shake blur compensation to the equivalent of four stops*. This lens automatically detects whether the user is panning during shooting or not, then switches accordingly to optimize operating control. Also, a malfunction prevention feature automatically detects whether the camera is mounted on a tripod.
* CIPA standards. When using an EOS-1D X with a 105mm focal length.
Excellent reliability
The mechanical structure has been reexamined and renewed, resulting in improved vibration-resistant, shock-resistant performance and durability that are expected of a new generation L lens. Dust-proof, drip-proof structure is applied to the mount, switch panel, zoom ring, and focusing ring.* A fluorine coating is applied to the foremost and rearmost lens surfaces for easier lens maintenance.
* Complete prevention of extraneous materials from entering the lens body is not guaranteed.
High-speed autofocus
High-speed, high-precision autofocusing is made possible by optimally matching USM control via inner focus system, high-performance CPU of the lens, and the camera’s AF algorithm.
