^^ Lol ... Lightroom is awesome. But not everyone wants to fork over 160-175 for photo software.
And the Tokina 11-16 2.8 Pro is a great lens for Crop sensors to get that ultra wide with not much vignetting.
The only issue I have with third party lenses, is that it's a hit or miss on sharp versions.
Not a huge notice, but something noticeable to the advance amateur or pro photographers.
The Tokina 11-16 Pro is actually one of those that I have seen many more sharp versions than none. And gives you 16-17mm of view (in terms of conversion to a 35mm standard look) and it depends on your crop sensor.
If you have a full frame camera ... the 14mm, 14-24 and 16-85 are great lenses. Both on the Nikon and Canon sides.
But of course also are the more expensive for being glass for FullFrame.
