What shutter speed do our eyes see?

Is the Canon EF-S 15-85mm L lens any good?
This is not a Canon L Series Lens (as of the date of this review, Canon has not released an EF-S L lens), but the 15-85 IS has many L lens qualities including three aspherical elements and one UD glass element. The Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens is sharp to the corners even with a wide open aperture.
How much does the canon 15-85mm lens cost?
Canons’ 15-85mm lens costs around £639 and is the natural replacement for their popular EF-S 17-85mm IS USM lens which can be had for around £380, due in part to this new lens becoming available. The extra 2mm at the wide end gives a useful wide-angle field of view, equivalent to 24mm on a full frame camera.

AI Servo AF performs well – and more specifically, well on the cantering horses and kids on bikes I was shooting with it. FTM (Full Time Manual) focusing is provided.
