Question about Tokina 12-24mm f/4 Pro DX for Nikon
Nikon D-3 provides specific image size for DX lens..All Nikon lenses fit well.But for Tokina 12-24 mm F/4 I observe at 24 mm it becomes full frame while at other lens starting from 12 mm the DX format has become cumbersome which needs Adobe Photoshop intervention.Is this a lens problem or otherwise. Can any body guide me.

Barrel distortion like you describe can always be a problem, especially at ultra-wide focal lengths like yours at 12mm. Some of this can be compensated for in software... Adobe Photoshop CS2 and Elements do a reasonable job, IMO, Bibble Pro (www.bibblelabs.com) does even better, especially with the 3rd party plugins like Percy perspective correction. These are things we have to live with when we have smaller sensors and ultra-wide angle lenses. There is nothing wrong with your lens, you will probably find that this distortion is minimized if you use a longer focal length (say 14mm) and/or stop down the lens a bit.. try f8, wide angle lenses have huge depth of field.

CS2 and Elements have a manual lens correction filter, once you know how much distortion your lens has at a particular focal length/stop you can save this out to be easily applied to all images. Bibble pro comes with a lens correction database which can automatically compensate for the distortions of your lens no matter what focal length/stop is used.
