Hello, Tokina has two wide angle lenses that get good reviews: the 11-16mm., f/2.8, and the 12-24mm., f/4 If Tokina had a 12-24mm., f/2.8, I'd buy it !!! However, since that it is not the case, I'll be getting the 11-16mm. f/2.8 My two main shooting interests are: architecture,(including interiors), and documentary, (including travelling), photography. I am buying that lens in New York in a very short visit and I still have a few doubts with regard to this lens. Were you in a similar situation to mine ?? Thank you very much, kind regards, igmolinav.
