SLRgear have reviewed the new Canon EF 24-105mm f/4L IS USM lens, which features a fixed aperture of f/4 throughout the zoom range and an Image Stabiliser that allows shutter speeds of 3 stops slower than normal.

“Bottom line, the Canon 24-105mm f/4 L is a really excellent optic, but one that struggles a bit along the edges and in the corners with full-frame bodies. As such, it’s an almost ideal candidate for use with DxO Optics Pro, particularly if you’re shooting with a full-frame dSLR.”
