Excerpt: Boasting the superb build, mechanical and optical quality found in the Canon L-Series Lenses and a widely used range of focal lengths, the Canon EF 24-105mm f/4 L IS USM Lens is one of the best and most popular Canon general purpose lenses made. The 24-105 L Lens quickly became one of my favorite and most-used lenses. If I had only one lens, this would be the one.
Excerpt: Gary Wolstenholme takes a close look at this popular 'L' series lens which covers a 4.4x zoom range, has a constant maximum aperture of f/4 as well as image stabilisation and an ultrasonic focusing motor.
Pros: Excellent resolution in the centre throughout the zoom range, Excellent performance towards the edges when stopped down, Great Image Stabiliser, Good build quality, Fast silent autofocus
Cons: CA levels towards edges throughout the zoom range a little high
