Canon EF 11-24 f/4 L – an Extreme Approach

TEST: Canon’s 11-24 mm f/4 has been called the world’s vidvinkligaste lens that is raktecknande. But what stands out against the Tamron’s counterpart – and how useful is actually 11 millimeters?

Canon describes the actual lens ideal for shooting landscapes, interiors and architecture. It must also have minimal distortion, which is a bold statement when it comes to lenses with that by viewing angle.

At an earlier look at the lens just before it was launched, however, got the idea that it is raktecknande. But of course we have measured it out during our test.

Robust construction

As can be read in the name so the included lens in Canon’s L-series which means it is supposed to be used for professionals and amateurs with high demands on their equipment. It also means that it is sealed against moisture and dust. Emphasis is on 1180 grams which is 80 grams heavier than the Tamron’s 15-30 f/2.8 and Nikon 14-24 f/2.8 is located one hundred grams less weight. The Canon lens is slightly heavier depends probably on the larger front element. If you look at the measurements, it is almost as long as wide, it distinguishes three centimeters to skilled advantage. But it’s a big piece. Mounted on a 5DS is a heavy thing that requires supporting the lens with your hand in order to take photographs in a sensible way. On the other hand, the fact is the case with most of the more expensive lenses for full frame sensors, with some exceptions. So 11-24 f/4 is not exceptional in this way – the advantage, however, is that it is pretty short, which means that the weight ends up fairly close to the camera body.

Both zoom ring and focus ring has a comfortable feel with a little bit of moderate resistance. It provides a comforting feel and are both nice and good to work with.

Fast focusing

As you could read in the paragraph before the feeling in the focus ring, even if you usually use the autofocus. Action shot of a USM motor (Ultrasonic Motor) who work both quickly and quietly. To focus with such a wideangle lens is a fairly easy history because the depth of field is so large. That focusing is slow is usually not a problem for this type of lens where the lenses should not be moved so far in the lens body.

We have just tested the lens on Canon 5DS, 5DS R new and which has the same fokusmodul as in the 1 d x. it should give as good conditions as possible for a quick and painless, and I don’t think there is any problem with other cameras either.

Requires new coating

Because the front element is so curved it becomes easy problem with light bouncing around and reflected resulting in lower contrast and poorer image quality. One of the solutions is so clearly a lens hood and lens are such that sits against movement, so filters with thread cannot use. But Canon has also used new coatings on the lenses to reduce problems with light that bounces off and causing reflections and ghosting.

Both the design and the coatings seem to be doing their job then the images that come out of the camera has nice contrast and stray light is handled in a good way.

High price

Compare it with Tamron’s version that we tested in the previous issue, it is a big difference on the price tag. Canon lens is just over 31 000, while Tamron’s costs in round throw 13 000 SEK. That’s more than double the price. The difference in focal length is not big, but noticeable.

The four millimeters separating 11 from 15 provides a greater difference than if we had been talking about a telephoto lens with the same difference in focal length. Tamron’s lens also features image stabilization and a larger apertur

Image quality

Canon’s latest wide angle may cost a lot and have a smaller aperture than some of its competitors. But it is very crisp. My focus is really, really good and out at the edges, it is not much worse, already from maximum aperture. The chromatic aberration is visible, but not problematic because it is easy to edit out afterwards. Vignetting is there even at maximum aperture, but dazzles you down a few steps to clear it.

As far as distortion is relatively absent, especially around 15 millimeters. Compare it with Tamron’s 15-30 mm at its most Wide mode is Canon lens for more raktecknande.

But none of the lenses have a disturbing distortion.

Summary

This is a lens that is not likely to end up in every photographer’s camera bag. Partly because it’s a rather extreme focal length, all subjects that do not fit the plates with 11 mm (or 24 for that matter) but also because it is quite a lot more expensive than the competition, which is also very good.But you will need the last millimeters wide angle, it can of course be worth the money.

It is a very good lens, there is no doubt, but the question is whether there is enough better to out-compete the more affordable options.
