Sorry its yet another newbie question on which lens to get. Using D80.
I've done the research on the lenses available, just wanted to get personal opinions on the above lenses. I'm going to look for it from the second hand market for below $600, so only looking at 3rd party lenses. Much depends on whats available too.
Tamron 11-18 - lightest, softer at edges
Sigma 10-20 - wider range, better CA control, sharp at edges, might have problem with light falloff?
Had a relatively good price for Tamron 11-18, and $100-$200 higher for Sigma 10-20mm though its alot newer. Personally preferred the latter if not for the available price.
I don't do large prints, at most for photo books not exceeding A4, wondering if the difference in quality (maybe at the edges) is significant? Probably using this for travel photography of scenery, architecture, and will bring it out for any group photo taking.
Also, is 10mm vs 11mm at the widest any significant difference? Never seen image comparisons before.
Appreciate any comments or points I need to take note of!
