Excerpt: I had this lens for a while now approx 2 years. The focus is very slow and sometimes it is blurry on a subject. I switch to manual to get exactly the focus I want. Which isn't that great because if the subject doesn't want to stand still, it is useless. This lens is okay for stationary subjects being very lit. The casing isn't that great either, I would have expected more of a metal finish than plastic.
Excerpt: I like the extreme wide angle and find it very useful in some of my work. However, I am very disappointed in the sharpness of this lens. There is a big difference when compared to by 18-200 USM IS zoom. I was particularly surprised because many reviews praised the lens' sharpness. I don't find that characteristic in mine.
Summary: I've had this lens for some time now. I've therefore had alot of experience with it. The quality is very good but no more than that. I was bitterly disappointed when almost all the photos in a shoot, suffered severe vignetting as a result of using the hood. Whilst this is a good size of a lens for certain purposes, you must be aware of its limitations, which for a Canon, are many.
Summary: I had one on a 550D for some time. I use Canon FF D cameras day in day out. I bought the 550D for a specific task.I found the 10-22 a bit flimsy and prone to flair. Most of my lenses are L, I would of bought L for the 550D if there had been any.Lack of quality glass in the cropped format I think holds the format back.Not a dreadful lens by any means, just not an L.
Summary: I'd heard great things about this lens, and having used the Tokina 11-16mm before, in addition to a Rokinon 8mm fisheye, I was interested to see how this lens would measure up. Unfortunately I've not been too impressed for the following reasons: 1) Distortion is poorly controlled, particularly at the wider end. I'd go as far as to say that the Rokinon performs better at 8mm than the Canon does at 10mm - then again, the Rokinon is a prime.
Summary: I bought this lens a year ago to take with me to the USA on a mini tour. I'm a landscape photographer and was in need of some extreme wide angles, however I recently upgraded to a full frame camera purely because of this lens, reasons as follows 1. At its widest angle the barrel distortion horizontally is terrible and barely fixable in photoshop however this is expected on a crop sensor camera (EFS lenses are not compatible on full frame cameras), its not so bad in the...
Summary: Aufgrund der vielen 5 Sterne Bewertungen habe ich mir dieses Objektiv bestellt und mit dem sigma 10-20 f3.5 verglichen. Viele Testberichte bescheinigtem dem Sigma eine miserable Performance an Bildrändern und Ecken, insbesondere bei Offenblende. Und ja, das Canon hat bei Offenblende und zwar auschließlich bei Offenblende die Schärferen Bildecken (wobei die Definition von Schärfe in den Bildecken bei 10mm Brennweite ohnehin relativ ist in meinen Augen).
