Compact, lightweight and with a lot of potential

To use this lens comes to my EOS 6D. Experiences for a comparison I have, among other things with my EF17-40 f / 4; EF70-200 f / 4IS; EF40 f / 2.8; EF100 f / 2.8; EF28 f / 2.8, EF 50 f1.8

I have long wondered whether I of this objective, in addition to my other, ever need, especially since I'm not a fan of zoom lenses. Meanwhile, I'm glad to have it, because it is compact and light, thereby gladly and often in Eisatz. The zoom range I think for most standard situations than enough sufficient. The picture quality and especially the color and contrast, I feel very good and I'm rather critical.

The 24-70 f / 4L IS is approximately d = 83mm L = 93mm and weight only 600g relatively small and light, yet there is still a really good and very quiet IS. A useful macro function is turned on quickly when needed. With 70mm and at close range (
The 24mm wide-angle are as (at full size) far enough to really get what's on screen and rich as a standard safe usually made. At the telephoto end, however, is already at 70mm conclusion as more tele would have been nice. With security would be the construction of bigger, heavier and illustration technically been accompanied by more compromises - then prefer that.

I've noticed that the raw images only average look, although the colors are very good but somehow comes not a real Wow on, anything but average, so I was initially disappointed. In Lightroom often enough a few adjustments in tone or some other moderate corrections and the image reveals a whole lot of processing resources. The color and contrast can be increased even more strongly, if required, without increasing the overall quality is lost. Overall, I know so not of other lenses, because the limits were reached more quickly.

The IS is almost inaudible and very effective, with some (more) Fortunately, I have already received images to 1 / 6s sharp. The AF does his thing well and not fall to continue, he meets, is quiet and fast.

Another note in terms of focus shift. The 24-70 f / 4L IS USM is said that at close range, simply by stopping down, the focus point at 1-3 cm shifted backward, so a back focus is created, which is not at maximum aperture there. This is in limited and applies only at 70mm at close range (approx 0,3-1m), you can switch here to Macro, this effect is no longer there, also, the image quality again visibly.

Conclusion: (Very) thought long and hesitated, but now very happy, because universal, lightweight, small, and with very good results.
