Hi there,
I'm trying to make a comparison between the Sigma 10-20mm F3.5 for the Nikon APS-C and the Tokina 11-16mm for the Canon APS-C.
I know its not a good idea to make comparisons between two different camera sensors generally, but no review for the Tokina 11-16mm APS-C exists on the Nikon side -- and I'm making do with what information is available. (Personally, I'm a Nikon APS-C shooter.)
One difference I noticed is that the Rating Scales are completely different in the two reviews.
The tokina 11-16mm (which is tested on a 8MP Canon) says that "very good" starts at 1550 and "excellent" starts at 1850.
The sigma 10-20mm F3.5 (which is tested on a Nikon 10MP) says that "very good" starts at 1650 and "excellent" starts at 1950.
So how can I make an educated guess as to how they would compare if they were BOTH shot on the 10MP Nikon? Can I draw any reasonable conclusions?
Furthermore, what assumptions should I make about these lenses if I were to move up to a 16MP sensor like the D7000s? Should I expect that these lenses will all uniformly perform worse / better / the same? Or is it a crapshoot?
