Ease of Use
For a professional Fifty-serial standard zoom, the Canon EF 24-70mm f/4L IS USM isn't too big and bulky, and not besides heavy either at 600g. While y'all can utilise it on a smaller APS-C body for a 38-112mm equivalent angle of view, it won't rest as well - equally demonstrated by the images above, it'due south a much improve lucifer for a professional-grade, total-frame photographic camera like the 6D.

As you would wait from a lens that costs this much, build quality is excellent, certainly upwards to the "L" moniker that denotes Canon'south premium lenses. The Canon EF 24-70mm f/4L IS USM feels very solid in your hand, even if the outer barrel and the filter thread appear to be fabricated from plastic. The focusing ring is simply as wide every bit information technology needs to be, and has a ridged, rubberised grip ring. It has no discontinuity ring, which is no large deal unless you lot wanted to use it on a very old motion picture body. The lens as well features a altitude calibration.

The Catechism EF 24-70mm f/4L IS USM boasts Prototype Stabilisation which Canon claims offers an reward of up to 4 f-stops over lenses without a stabilizer. This is activated via the On/Off switch on the side of the lens. If the camera trunk supports information technology, Canon's IS applied science is also able to detect intentional panning movement and automatically switch from the Normal IS mode to the Panning IS mode.

The new Macro / Lock switch turns the Canon EF 24-70mm f/4L IS USM into a very competent macro lens with a close focusing altitude of 20cms, rather than the standard 38cm, and a magnification ratio of 0.7x. This specification means that the Canon EF 24-70mm f/4L IS USM will double upwardly as both a standard zoom and macro lens for many users.
Macro mode is activated by pushing and property the switch to the Macro setting and rotating the zoom ring to the yellow Macro setting at the terminate of the range. You can then slightly fine-melody the composition of the prototype past rotating the zoom ring through the distance indicated by the yellow line, with the respective yellow line on the distance calibration indicating th focus range.
The same switch too activates the Lock function - set the focal length to 24mm and move information technology backwards to the Lock position to prevent the zoom mechanism from creeping when the camera is pointed downwards or in storage.

The final control on the lens barrel is a focus manner switch with the usual AF/MF settings. Note that this lens usefully offers total-time manual focusing even when AF is selected.

At the 70mm focal length the angle of view is 29 degrees.

Focusing
The Canon EF 24-70mm f/4L IS USM lens has a broad-enough focus ring. There are hard stops at both ends of the range, making it easier to fix focus at infinity. Polariser users should be pleased that the 77mm filter thread doesn't rotate on focus.
When it comes to motorcar-focusing, the Canon EF 24-70mm f/4L IS USM zoom is a quick performer, taking nigh 0.15 seconds to lock onto the discipline when mounted on the Catechism EOS 6D that we tested it with.
We didn't experience much "hunting", either in proficient or bad light, with the lens accurately focusing almost all of the time. It's too a fairly tranquility performer, thanks to the congenital-in USM (Ultra Sonic Motor), which makes this lens quite well-suited to video recording.
Chromatic Aberrations
Chromatic aberrations, typically seen as royal or blue fringes forth contrasty edges, are impressively well controlled with this lens - the examples below show the worst-case scenario.
Light Autumn-off
With the lens wide open at f/iv, you can come across some slight light fall-off in the corners. Stopping down helps, although to completely get rid of this phenomenon, yous will need to utilise an f-stop of f/v.half-dozen or smaller.
Barrel distortion isn't too bad at all at the 24mm wide-angle focal length, disappearing completely at 35mm.

Macro
The Catechism EF 24-70mm f/4L IS USM also usefully doubles upwards as a competent macro lens. When the Macro mode is activated the close-focus betoken is at 20cm from the picture show/sensor plane, and Catechism quotes a maximum reproduction ratio of 0.7x for the lens. The following examples illustrate how shut you tin can get to the subject field in both standard and Macro modes.

Bokeh Examples
Bokeh is a give-and-take used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such equally smoothen / creamy / harsh etc. Canon have employed an iris diaphragm with 9 rounded blades for a pleasing rendering of the out-of-focus highlights. Based on what we have seen, we can say that they largely succeeded. Below you'll discover some examples, merely you are also encouraged to check out our sample images.
