With a fixed f/4 maximum aperture and an AT-X Pro designation it would be reasonable to expect a lot of the Tokina 12-24mm.

Handling and ergonomics

f/4 performance at 12mm setting

With the increasing popularity of digital SLRs with smaller than full frame digital sensors, there has come the demand for wide angle lenses specifically designed for this format. The Tokina AT-X 124 Pro DX 12-24mm is one of several new lenses intended to fit that need.

Tokina's latest version of this classic wide angle optic for Canon or Nikon APS-C format DSLRs sports a fast, smooth autofocus motor in addition to the constant f/4 maximum aperture and costs around £500.

Excellent sharpness; especially at 12mm; Very good build quality; Fast to focus; Keenly priced

Chromatic aberrations towards the edges; especially at 12mm; Barrel distortion; especially at 12mm

The Tokina 12-24mm f/4 AT-X PRO DX II provides a narrow field-of-view, and a full-frame equivalent of 18-36mm. The lens features 13 elements in 11 groups with two aspherical elements designed to reduce chromatic aberration. The f/4 maximum aperture is constant throughout the zoom range.

High quality built.

everything; especially AF/MF ring switch

slightly softer on long end; but still sharp at F8

A wide-angle zoom lens designed for Canon and Nikon APS-C cameras, the Tokina 12-24mm offers good value and performance in a well-built package. Be prepared to engage in some post-processing work to eliminate a few of its flaws, however, like sporadic chromatic aberrations and slight distortion at...

Excellent build quality; Reasonably sharp throughout the focal range; Good colour balance

Not as wide as some other third-party (and first-party) lenses; Some chromatic aberration and halation issues

I used this lens on a Canon 500D/T1i body. The build quality of this lens is that of a TANK! Feels solid, but feels like it outweighs an entry-level body. I adjusted to it, and never had a problem with it.

Image quality; tough build; zoom range; constant aperture F4

my lens crapped out on me; slow aperture F4

auto focus works great than i expected. faster than NIKON D series lens. both lens don't have a internal motor. but this lens looks like toy..compared with nikon lens...cheap lens look...doesn't look like any nikon lens.. but it's ok... overall i can say OK..photo image is sharp and crisp.

After much research and reading many online reviews I chose the Tokina over the Nikon. This decision was largely made because of cost with the Nikon lens being so much more expensive.
