Canon EF 24-70mm f/4L IS USM preview
Tuesday, November 06, 2012 Lens Review
The latest in the L series, the Canon EF 24-70mm f/4L IS USM is an ideal transtandard lens for reporting and can also make a good choice for portraiture. Versatile, it can also function as a macro with a reproduction ratio of 0.7x, Canon having worked hard to optimally match up the optical elements.
The optical formula of the Canon EF 24-70mm f/4L IS USM integrates two aspherical and two UD glass lenses as well as an ultra-low dispersion lens, and benefits from a Super Spectra coating to ensure optimal contrast by fighting against glare and ghosting.
As an L series lens, the Canon EF 24-70mm f/4L IS USM’s optical formula is particularly well thought-out. Although many observers expected simply a stabilized version of the 24-70mm f/2.8, this stabilized 24-70mm sees the light of day at f/4. This more modest aperture will be less likely to generate a blurry background than if Canon had opted for f/2.8, but the lens still counts nine circular diaphragm blades with which to handle the bokeh.
The Canon EF 24-70mm f/4L IS USM embeds Canon’s latest hybrid optical image stabilization system, resulting in a gain of 4 stops, and iable to correct angular displacement and shift during macro photography. Its autofocus is powered by a USM system that allows for continuous adjustment.
The Canon EF 24-70mm f/4L IS USM’s finish is consistent with L series standards, and the zoom and the focus rings have been redesigned. The lens is tropicalized and resists both dust and moisture. It is possible to lock lens deployment while traveling, and both front and back lenses have been treated with a fluorine protective coating to keep them clean even in light rain or in dusty conditions.
The Canon EF 24-70mm f/4L IS USM will be available in January 2013 at a price of 1,699 euros.

I do not believe
Most likely incorrect tests.I'll explain why DxO does not provide graphical results of the tests but only their personal considerations.So as another to drive the conclusion

I do not believe
because your tests are so far from reality?

Re: I do not believe
Interesting point but you have to remember you're not really comparing apples to apples here. The link you provided compares a Canon f/4 VS Sigma f/2.8 which isn't a true apple's to apple's comparison. More like a peach and orange.
DXO Lab tests thousands of lenses under Strict controlled environments, I highly doubt they're fluffing up the test results. PLUS "IF" they were...what are they gaining from doing so? Something to think about. Reply |
