I have previously had a Canon EF 17-55mm f / 2.8 IS to my 60D which has been my closest alternative to wide-angle. However, it is often the experience of having a wider range of experience.
For a few years, I bought this lens, and I think it's a top lens in many ways, and I came across it for SEK 1,950 in really good condition at Tradera, which I almost look like a theft hehe. It became a ND1000 filter for some thousand flaps (has more 77mm lens I have use for it on too) and a backlight protection of the DOOR brand for any dog rap through amazon.de.
Immediately when I put on the new window, I thought something like "Why did not I buy this earlier?". It's really an incredibly fun slider to shoot with, and useful for more things than you can imagine. It requires some creativity to maximize it, but I think most people who look at this lens know what they are looking for and what is required of the photographer or have the desire to learn.
The pictures get really good, even better than I expected. Contrast-rich, provides powerful strength in most situations and a USM AF that is fast but not the fastest in Canon's arsenal. It's a pity that it does not have IS, but you can take very good photos in darker situations anyway. Personally, I find that it is usually on a tripod, so the IS issue is not so important. Building quality is just like other top-level lenses in the EF's series, such as 17-55 / f2.8. Just the lenses are really alike, when it comes to look, feel and quality. A big advantage is that this slider does not expand / "expires" in the same way as 17-55 f / 2.8 when zooming, but it does not happen internally.
On the outskirts of the picture, there is a lot of CA as users and reviews say, especially if there are big contrasts (leaves and light skies, for example). This is something I anticipated before buying and it's not that bad, but definitely a minus. The image is distorted to the edges of the image, especially at 10mm. This can be both a plus and a minus depending on the photographer. Personally, I like it and you can use it to its advantage for creative images.
I would probably go so far to say that this is the second best EF's lens after EF's 17-55 / f2.8 IS USM.
With this lens, I feel that my camera bag is "complete" and ready for all situations. Other windows I have are;
Canon EF-S 17-55 / 2.8 IS USM, Canon EF 70-200 / 2.8L IS II USM, Canon EF 100 / 2.8L IS USM Macro and it covers all my needs!
I strongly recommend this lens, especially if you can find something used for under half the price or lower, it's a very affordable purchase, given that you can get so many different photos with this lens! Be aware, however, that it is best on stand when IS is missing and that you will get some CA in the edges (can always be fixed in mail) as well as distortions that may be +/- depending on the person. This is my new love for my macro lens.
