I am selling it because I got the Nikon 17-55mm f/2.8 a few months ago, and I am not using this Tokina anymore. They are too similar to keep both.
I would say the big selling points of this Tokina are that it is very wide (closer to 15mm really) and has gorgeous bokeh.
What it has in common with the Nikkor is it's professional build quality, weight and size. It is somewhat soft in the corners at f/2.8, and has vignetting at 16mm wide open. However, it is incredibly sharp stopped down.
I realize that the Tamron 17-50 might be a cheaper choice and slightly sharper at f/2.8. However, this lens has some advantages over the Tamron:
- far better build quality
- wider
- smoother out-of-focus backgrounds
Either way, it's a very good lens. Let me know if you're interested or have questions. I'm just dropping it here and on Facebook before I post it on eBay...
