Lens Review: EF11-24mm f/4L USM in Landscape Photography

In the world of landscape photography, the demand for wider and sharper lenses seem to be echoed by professional landscape shooters all around the globe. Answering these demands is the EF11-24mm f/4L USM, Canon’s top-of-the-line ultra-wide angle lens for full-frame DSLRs. Armed with this and an EOS 5D Mark IV body, photographer Shirou Hagihara gives us his take on what makes this lens such a must-have for landscape photographers everywhere. (Reported by: Shirou Hagihara)


Experience the world of wide angle far beyond the scope of the naked eye

There were three times where I found myself stunned by the EF11-24mm f/4L USM. The first time was when I first purchased the lens. As the price of this lens is top-of-the-line even among the L-lens lineup, it certainly made its impact on my wallet. The second time was when I first held the lens after purchase. This lens is not exactly known for its light weight and compact size, but holding it in my hands for real, I realized just how much it was going to make its presence felt, especially for shoots that involve moving it around.

The third time was when I first saw the images that I had shot with this lens. The amazing image quality was enough for me to laugh off and forgive the first two instances. 

Image sharpness is more or less a guarantee here. What is more amazing than anything else is that even at a focal length of 11mm, straight lines are generally depicted straight, and there is no hint of unnatural distortion even at the peripheries of the image. Even chromatic aberration is suppressed to a level lower than other conventional ultra-wide angle zoom lenses in the same class. This lens will probably shine brightly, especially in genres such as landscape photography which demand the highest detail reproduction power possible.

Shooting at an aperture of f/16 produced a beautiful starburst effect without any trace of flaring, while ghosting is still slightly visible though remaining in the tolerable range. The edges of the image are depicted free of distortion, making it extremely pleasing to the eye.


Nonetheless, it would be better to know the features of this lens before making a purchase. Firstly, as the front element of the lens is rounded and protrudes out, you will not be able to use it with conventional screw-on filters. Instead, you will have to use a rear gelatin filter, which you insert into the filter holder at the rear of the lens. Secondly, the lens design integrates a petal lens hood. Sunlight can still enter lens easily, however, so there might be some scenes where ghosting may still occur. Thirdly, when mounted onto a large DSLR body such as the EOS 5D Mark IV, the entire setup becomes rather front-heavy, thus, a sturdy tripod and tripod head are essential. 

However, these points are likely to be insignificant when the impressive image quality is taken into consideration. This is a lens that you will definitely not regret buying.

On the other side of the 11mm end of this beast of a lens, the telephoto end sports an easy-to-handle 24mm focal length, which allows for faithful portrayal of scenes. Image quality is sharp from corner to corner, with exceptional performance when stopped down to f/8 or f/11.
