The EF 24-105mm f/4.0L IS USM is a professional EF mount wide-to-telephoto zoom lens. It was introduced by Canon in 2005 to complement the well-regarded 17-40mm f/4L USM and 70-200mm f/4L USM.
The lens is often compared to the other L series zoom of comparable range, the 24-70mm f/2.8L USM, losing 1 full stop but gaining image stabilization (IS) in return. The Image Stabilizer (IS) provides an improvement in image stabilization equivalent to using a shutter speed three stops faster . It also has rubber gaskets for moisture and dust protection, although this feature is only fully realized if the photographer uses a weather-resistant camera body. Some early production models of the lens had a flare problem (reportedly the first 10,000 batch) and Canon offered to repair them for free.[2]
On a 1.6x APS-C camera body, this lens' field of view is equivalent to that of a 38mm - 168mm lens on a 35mm film camera; this is a very useful range, covering most normal to medium-telephoto needs.
Optical scheme of Canon EF 24-105L IS USM lens
- The lens includes sealing against dust and water, although it is not waterproof.
- It includes an 8-bladed curved diaphragm which remains nearly circular from f/4 to f/8.
- Uses common 77mm filters.
- Characteristic of zoom lenses, it exhibits some barrel distortion at its shortest focal length.
- This lens is available in a kit packaged with the Canon EOS 5D Mk II.
