As we continue our survey of wide-angle lenses currently on the market, let’s take a look at the Tokina AT-X 11-16mm PRO DX on a Nikon D7000 and on a Canon EOS 7D. |

Announced at PMA 2009, the Sigma 10-20mm F3.5 EX DC HSM Canon wide-angle zoom lens features a constant f/3.5 maximum aperture (EX) and is equipped with a hypersonic motor (HSM). |

The Canon EF-S 10-22mm f/3.5-4.5 USM, a very light and small equivalent to a 16-35mm on a 35mm camera, is well suited for landscape or indoor photography. For example, the non-rotating front element eases the use of polarizing and graduated filters, which are very popular for landscape photography. It is to be noticed that this wide angle zoom can focus at a distance down to 24 cm. Its Super UD glass lens and its two aspherical elements perform should give it a good image quality. Let's see if the DxOMark measures confirm this. |

Older but still interesting! You can see the DxOMark test results for the Nikon AF-S DX Nikkor 10-24mm f/3.5-4.5G ED and the Canon EF-S 18-55mm f/3.5-5.6 II USM. |
