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...

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.

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.

Like most Tokina lenses, this is an awesome lens for the money. It's only real weakness is a very moderate amount of CA, which is almost unavoidable with UWA lenses. As the official review says, stopping down clears up the softness at the long end, and the short end is amazing.
