Overall
Owner since: 1 year
Price: €70-
User profile: Semipro
Cons: A bit soft wide open, AF not the fastest (unnnecessary with wide-angles), heavier than comparable Sigma 17-35/2.8-4.
Pros: Stopped down slightly performance becomes convincing and makes this Tamron a very versatile, not too big, rugged lens with high optical quality.
Summary: A very good performer for a low price (like its brothers SP 28-105/2.8 and 200-400/5.6 LD), but rather rare.

Cons: - very Vulnerable to flares - very low optical performance completely open (just gets usable at f/4) - is vignetting much - strong distortion at 20mm wide open
Pros: - metal construction - front lens doesn't rotate while focusing - cheap fullframe 20mm wideangle !
Summary: I use this lens on my Nikon D700. Compared to other Nikon Lenses it delivers very different colors than Nikkor Lenses. Personally, I love the way this lens renders blue and green tones.
