Excerpt: A professional standard zoom lens covering the popular 24-70mm focal range, which sports a constant fast maximum aperture of f/2.8 and silent focusing with full-time manual focus override. This lens carries a very high price tag of around £2300, which is really quite expensive for a standard zoom lens. In this review we'll take a look at how it performs and whether the premium price is justified.
Pros: Very good build quality, Excellent sharpness, Relatively lightweight, Low CA, Low distortion
Cons: Reassuringly expensive, Falloff at 24mm is quite pronounced at fast apertures and doesn't even fade out until f/8
