Tokina AT-X Pro 17mm F3.5
I bought this lens "new/old stock" boxed, with original caps/hood, etc...
$190.00 total shipped. I'm honestly in love with it.
Wide open at F3.5 the corners aren't sharp. At F5.6 they're sharp enough. At F8, they're perfect.
17mm on FX is pretty darn wide. To get this wide for under $200.00 is awesome.
It's on par with the Nikon 20mm F2.8D, I would say.
It's not as good as the Nikon 20mm F1.8G. I owned that lens before, and it's better.
But at this price, I'm keeping this Tokina.
