Matt: For the record, I shoot a Nikon D7000 and am an amateur photographer - so take this review as you wish. I've been thinking about buying a wide-angle lens for a bit and wanted to test a number of options, including non-Nikon branded lenses. I read some reviews that Tokina was a solid alternative to Nikon. For the most part, I can understand the reviews and would agree. That said, there is a critical issue I wanted to share. I am not entirely sure why this happens, but when stacking a circular polarizer on the lens, you get automatic vignetting from the edges of the polarizer when at the lower end of the zoom - 11mm in the case of this lens.To get rid of the issue, the lens had to be at the top end of its zoom capabilities - 16mm. But the problem doesn't stop there. To top things off, when using a Cokin P-series filter holder, the edges of the holder would show in the image - even at the 16mm. To sum this up - if you don't plan on using any filters, I'd recommend the lens. But if you plan to do a lot of landscapes (like myself), I wouldn't recommend it. Cheers.

Mark: Excellent lens! Highly recommend renting it. I will likely end up buying it. One warning though... I rented the suggested graduated filter listed on the same page and it made very large vignette's at 11mm. I ended up having to do significant crops on several of my images. I recommend not using the filter listed.
