    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.
