aunque el peso es algo elevado la calidad de la optica impresiona acercandose a la que pueda tener una focal fija...el efecto angular es ciertamente impresionante y te amplia la capacidad de percepcion de el entorno,es un objetivo totalmente necesario para cualquier usuario de réflex!!!!!!

The 12-24mm Tokina is an ultrawide angle lens intended for DX sensor format cameras. It gets the job done, although it's not perfect. (Mine's is for a Nikon.) The build quality is good, and reliability wise I've had no problems in 3 years of service.

at F4 (constant) it's reasonably fast; Allows pictures to be taken that simply could not be done otherwise; Nice color rendition; contrast doesn't seem noticeably different from my other DX lenses; Autofocus is acceptably fast; but see below; Zoom scale is evenly and widely spaced; this is good...

As with all ultrawides using the sun hood is required; and it is a very big lens; Distortion is also an issue; which is common to ultrawides; The autofocus is a screw drive; so cameras lacking an internal focus motor (D40) are out of luck; No aperture ring for manual work; Past about 14mm the lens...

THE TOKINA AT-X 124 IS HIGH QUALITY PRODUCT.IT HAS GOT A LONG LIST OF FEATURES LIKE BUILT IN AF MOTOR DRIVE,ONE TOUCH FOCUS CLUTCH MECHANISM, FAST AND EASY MANUAL OVERRIDE. IT HAS GOT A WIDE ANGLE ZOOM, WITH MAXIMUM FOCAL LENGTH OF 24MM AND MINIMUM OF 12MM.

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. What Digital Camera sees if it lives up to the self-proclaimed hype...

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.

Great lens. Have taken some long exposure night photos with this lens. Sturdy built. Will recommend this for all those who love photography.

This new version of Tokina's 12-24mm super wideangle lens incorporates an autofocus motor in its Nikon version, so it's now compatible with Nikon cameras which don't have a motor in the body, including the D40/D40x and D60.

The latter lens has been slightly modified by Tokina, the AT-X 12-24mm f/4 Pro DX II now includes an integrated motor that makes it compatible with all current Nikon DSLRs, including the entry-level models. In addition, the coatings of the lens have been updated to offer better flare protection.
