EF 24-70 f2.8L USM

1.The Canon EF 24-70mm f/2.8 L USM Lens is an impressively high performing zoom lens. I regard it as one of the best general purpose lenses available.

2. The solid 24-70 L focuses quietly and very fast thanks to Ring USM

3. The 24-70 L is sharp in the center at f/2.8 at all focal lengths. Corners are also very good with one exception - the extreme full-frame corners are soft at 28mm and below until stopped down to at least f/8.

4. The Canon EF 24-70mm f/2.8 L USM Lens' 77mm filter diameter makes sharing filters with most of Canon's other L-Series zoom lenses easy

5. The Canon EF 24-70mm f/2.8 L USM Lens focuses close enough to take close-to-macro pictures. It will not take a 1:1 macro shot, but capturing the flowers around your house is one of this lens' capabilities.

即使是蔡斯,大部分微距也就是做到1:2而已,又何必要求24-70做到1:1呢?
