Canon EF 24-70mm f/4.0L IS USM Review
Photographer Christopher Frost published an interesting review of the relatively new Canon EF 24-70mm f/4.0L IS USM and test to see how good it is and even more importantly if this lens is worth the hefty some that Canon is asking for it.
the Canon EF 24-70mm f/4.0L IS USM is newer than the older Canon 24-105mm f/4 and although it has a shorter focal length it is not much smaller in size. It does seem to have a very good image stabilizer and an interesting macro mode (not 1:1 macro mind you) and the image quality is good although not very different that that of the older 24-105mm (which was never considered to be a superb lens).
The lens has some barrel and pincushion distortion but nothing too bad, It isn’t very good at resisting flare and the macro mode is potentially very useful but you will need to stop down to at least f/5.6 (preferably to f/8 if you can).
At the end of the day it is a decent lens but probably a bit too big and to pricey to be really attractive for a lot of potential buyers.
The Canon EF 24-70mm f/4.0L IS USM is pretty expensive at almost $900 on Amazon.
