The 5DII would have also been more accurately compared with the Canon EF 24mm f/1.4L II lens (according to the Exif data the sample photo was shot at 24mm).
The iPhone 4S's camera is a fixed focal length while the Canon lens they used is a zoom lens. Zoom lenses trade certain attributes for the flexibility of being able to zoom, one of which is corner softness at wide open apertures. The 24-70 is a decent all-around lens, and I have used it extensively, but I have never encountered a zoom lens that reaches the same image quality as a fixed lens for the same focal length.
- sk5t 15y agoWith those little bitty scaled-down snaps, there ought to be no discernible corner softness with a big 2.8 pro zoom (and IMHO there isn't); we're mostly eyeballing center sharpness, white balance, and range of contrast. Of course there'd be less barrel distortion with a prime... but it doesn't stand out either way with these scenes. You can see there's a little less blowout on the shiny roof with the 5D, and quite a bit more detail in the shadowed city streets. Certainly a higher color temperature, probably more accurate. But the 4S is quite impressive nevertheless. No apparent vignette issues. These photos are not useful for assessing high ISO noise/grain...
- rimantas 15y agoDon't know about Canon, but for Nikon there are 24-70/2.8 and 70-200/2.8 which are on par with fixes.
