Re: Nikon 2.8/10,5 Sigma 3.5/8 or Tokina 10-17 ?

Hans,
C'mon! Do you think I'm a rookie? ;-) Please be sure that having 30+ years in serious photography (including professionsl one) and being MS in physics (you probably know that optics is the part of physics) I know how to keep lens clean.
For your information: Flares shaped like spots, polygons and somethong like that are NEVER caused by grease, fingerprints, scratches etc. These defects cause parasitic beams, star-like spots, additional lighting and anything else BUT spots and flares. I hope I do not need to refer to a fundamental optics to confirm that. Please just trust my experience in physics (and optics particulary) and photography.
Sorry and Best Regards,
Alex

You might need to clean your lens.
The Nikkor 10,5mm has very little flare compared to many standard
rectilinear lenses.
I have done a lot of panos with direct sun with it and never seen it.
It is almost as good as the Canon 15mm
But like all very short lenses it is extremely sensitive to slightest
amount of dust grease, fingerprint etc on the lens.
And avoid stopping down too much. The 10,5mm has its best performance
at 4-5.6
