Look no further, because with the TOKINA ATX 12-24 PRO you have the best wide-angle zoom lens found that currently there are on the market. This lens has (both the more expensive Canon EF-S 10-22 as well as the excellent Sigma EX 10-20) beat the competition in the testing of the well-known photography magazines sometimes quite significantly!
The Tokino 12-24 is both in terms of light intensity (F / 4) as well as in terms of distortion and sharpness of the aforementioned competition one-upmanship. It features etc. on a Canon EOS 20D / 350D / 30D (Crop factor 1.6) over a focal range of 19.2 to 38.2 mm, which should be more than enough for those situations where again from close range to as much as possible on the picture. For all major focal lengths you then anyway be standard zoom or fixed focal length in his favorite luggage.
I bought the Tokino months ago two and a half because of the superior test results, tested extensively in the following years and am thrilled completely from the lens. It produces on my EOS 30D tack-sharp photos of the entire zoom Berich with acceptable vignetting and low distortion in the peripheral areas.
5 stars for a fantastic wide-angle! Access!
