The Canon EF 24-70mm f/2.8L II USM is a standard zoom lens that every pro wants. With f/2.8 it has a strong light value, which makes it able to cope with a large variety of lighting situations. It also works both inside and outside, in good weather or bad, thanks to it's protection against water and dust. This combination makes this 24-70mm standard zoom properly suitable for traveling or photo-blogging. Compared to the previous 24-70mm f/2.8L, this one has a restyled (smaller) design, more lens elements, 145 grams less weight, and a larger filter size (82 instead of 77).
