Recommendations on wide angle lenses

[greybeard]

I used to love the Tokina 12-24 on my D7000, I found the 11-16 too highly priced and a very specialist zoom range, I also used screw on slim filters on the 12-24 without issues.

I have the Tokina 12-24 that I use on both APS-C full frame. (it covers FF from 17mm to 24mm). One of my favorite lenses.
