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

I am using this for indoor pictures of rooms, offices. This Tokina 12-24mm F/4 coverage is just right for this purpose. The lens focuses with the smallest of details being stunningly sharp. Changing focal lenght is smooth and quick, the ring being well placed, no hassle.

Dials easy to see; Easy Handling; Light Weight; No vignetting; Quiet focusing; Seems very durable; Sharp Focus

Great wide angel lens.

Picture quality is up there with the best and build quality is superior to Nikon's 10-24. The constant f4 is a pro feature. The zoom and focus rings have a smooth and well dampened feel and the lens is a delight to use. It will also stand up to the knocks it is likely to get out on the street.

Durable; Great Picture Quality; Simple Controls
