gugs Offline Image Upload: Off p.1 #1 · Super-wide question Does anybody have any experience with the 10.5mm fish-eye and the de-fishing option of Nikon Capture ? Does it really allow to go virtually much wider than with 12mm on a 12-24mm zoom ? What about picture quality, remaining distortion ? Any feedback welcome. Any other solution to go wider than 12mm without the typical fish-eye effect? Edited on Nov 10, 2005 at 12:05 AM Nov 03, 2005 at 08:11 PM

gugs Offline Image Upload: Off p.1 #3 · Super-wide question Mert, do you have any example with the same subject photographed at 10mm and 12mm from the same place to see the difference (are those 2mm worth the investment ?) Edited on Nov 10, 2005 at 12:05 AM Nov 03, 2005 at 08:36 PM

walter23 Offline Image Upload: Off p.1 #5 · Super-wide question How does the distortion of the sigma compare to the tokina? One thing that's always bothered me with samples I've seen (and tests in store) has been the complex wavy distortion... I'd prefer simple barrel distortion which is easier to correct.

turnert Offline Image Upload: Off p.1 #6 · Super-wide question You do NOT want to de-fish 10.5mm images as a substitute for a true rectilinear wide angle. De-fishing will certainly straighten out the image, but pixels toward the edges are stretched. A round column will become an oval, a face will get distorted, and the stretched pixels will look soft in many cases. With the 10.5mm, keep people, in particular, near the center of the image. Capture also crops a bit of the image during the de-fish. Edited on Nov 10, 2005 at 12:05 AM Nov 04, 2005 at 07:32 PM

Mert Offline Image Upload: Off p.1 #7 · Super-wide question Sigmas distorsion level is better than the Tokina @ 12 mm. Edited on Nov 10, 2005 at 12:05 AM Nov 04, 2005 at 08:15 PM

walter23 Offline Image Upload: Off p.1 #8 · Super-wide question Actually I just got the tokina 12-24mm and it's phenomenally better than the sigma, as far as curved distortions are concerned. There is minimal barrel distortion and that's about it. The only fault I can find with it is the chromatic abberation (blue/yellow fringing near high contrast edges), but it's about what you'd expect from a super-wide and is much more tolerable to me than distortion. It takes a lot of effort to see fringing, distortion sticks out to any observer. Edited on Nov 10, 2005 at 12:05 AM Nov 09, 2005 at 10:35 PM
