| I always appreciate such comparisons, so thanks very much for posting this. These kinds of comparisons are much more useful than simple example images (which are fine too). I also think it's best to shoot these kinds of comparisons without hoods, because that shows up the flaws in the lens better (IMHO).... |
I tend to agree, however, doesn't that give lenses with more recessed front elements unfair advantage? |
Maybe they are better designed, so any advantage would not be 'unfair'. It's still telling you something about the lenses performance. Lots of lenses absolutely need a lens hood whilst some are great without them. |
Agreed. And as kiddo says:

My point is hoods prevent omnipresent stray light from entering the lens, thus improving contrast and reducing flare. A more level playing field as it were. Perhaps tests without hoods may show only coating effectiveness differences.
