Cons: Terribele amount of Chromatic Abberation in corners and overall unusuable corners due to total lack of sharpness even at F8 - F11. I've returned my copy to Canon and am waiting for their verdict. Used on Canon 60D. It could be that this lens simply isn't good enough for 19 mexapixels. I've owned a Nikon 12-24 which was much better in every aspect!

Pros: lightweight, flare resistance, nice sunstar

Summary: Avoid this lens at all costs and go for the Tokina 11-16 which is beter at alomst al points except flare resistance

Cons: Parasol not included and of enormous size. High price.

Pros: Low distortion, good construction, pity not creating constant width. Good saturation and color, fast, quiet, and effective AF (EOS 20 d and 50D).

Summary: Indispensable for landscape. Highly recommended.

Cons: Too expensive for what it is. Too dim (f/2.8 would be a nice starting point for a zoom). Not nearly as sharp as Tokina 11-16.

Pros: Lightweight. Fast and accurate AF though.

Summary: Mediocre UWA for crop sensor cameras.

Cons: Terrible chromatic aberration and edge sharpness, even for such a short length - the lack of sharpness was visible anywhere off centre (not even mentioning the corners) on a postcard offset print! Terrible build quality: the lens broke in half when dropped 10 inches in a padded case and was refused a warranty repair by Canon Australia. Very expensive. No lens hood.

Pros: Very wide at the short end and extends to almost a "normal" length i.e. 35-50mm film. It is ideally suited for my dramatic close-up and wide shooting style. Fast autofocus.

Summary: I was very disappointed to have such poor performance for such a well-reviewed lens - so much so that I thought I may have a faulty lens. However, Canon Australia have confirmed, when it was repaired, that there was no fault. This lens was so expensive and problematic that I have changed systems!

Cons: f 4.5 on the long end makes AF hunt in low light

Pros: sharp, fast AF, smooth zoom, low distortion

Summary: one of Canon's best - skip the lens hood as it's silly looking and the 10-22 is very flair resistant

Cons: lack of a lens hood. this is an "L". I don't care Canon didn't name it like that. So why they don't think to give us an hood?

Pros: everything. Great lens indeed! Very sharp and well corrected. Great colors. Happy to be able to avoid to shoot at f 8 in order to get a great picture. I own a 50d, which is quite sensitive to little apertures, and what I get shooting at f4-5,6 totally satisfy me.

Summary: Buy it!

Cons: Corner fringing, no hood, layout of focus and zoom rings different from other Canon zooms

Pros: Very wide, rectilinear, good colours, light weight, great performance at f/8.

Summary: Spectacular performance at f/8, whatever the focal length. If someone had told me 20 years ago I'd be using a lens like this I would have laughed at them. A few corner CAs but very correctable in Ps.

Cons: bit expensive, some CA´s, lenshood missing

Pros: strong resolution (the corners are a bit more week), nearly without distortion, nearly without light falloff, easy to handle, good design and of course 10mm, which is really greaaaat, nice colours

Summary: reading the "Mr. goose" so I think the guy was really drunk or bought a rippoff-copy - all is nonesense, this is a really great lens, a bit expensive, but the allround-quality do justify the prize. Its a great, very wide lens, get one for the 7 D, 60,50,40 D!

Cons: The usual: no lens hood. Filters are expensive at this size.

Pros: Very sharp and not a great deal of distortion, even at the wide end if you keep the lens on centre to subject. This lens excels in keeping CAs down to a minimum and in providing sharp, contrasty results throughout its range. Smooth focus action, very good build quality.

Summary: A little pricey but highly recommended if you want ultra-wide. That said, I find I do not use this lens as much as I thought I would as I find the more natural perspective at 17mm (27mm 35mm equivalent) onwards best for landscapes etc. But if you want wide for interiors and special effects this lens is essential. For the money this is a 5 star quality lens.

Cons: no lenshood!!! normal but stabil construction, some CA´s, corner-rendition sometimes a bit week (f3.5-5.6) but that´s quiete normal for UWA, price for a new one

Pros: Very sharp (in the center may be the best UWA on the market, only the Tokina 11-16 come close), few vignetting (from f5.6), very few corner-distorsion, colour-rendition is similar to L-lenses, light-wight, easy tu use

Summary: Optics are really brilliant (always knowing whats possible with an UWA), construction is average but solid. The negative point: Price for a new one and what happens with the lenshood??? (moneychunker from Canon....)

Pros: Fast AF; more reliable in sunlight, then also very sharp. Very useful range. Build quality ok.

Summary: A still good (good-weather) lens, even if a little expensive.
