I will get a new fast wide angle soon. As soon as I can make a decision. I have narrowed it down to these choices (Ohters either aren't wide enough or too wide or I have read bad reviews about them somewhere or of course they are too expensive for me): sigma 24 f/1.8 sigma 28 f/1.8 sigma 30 f/1.4 ( I have also considered the tokina 11-16 f/2.8 and tamron 17-50 f/2.8) I've seen plenty of great pics from the 30mm recently but not so much of the others. I tried the search feature but I can't find anything that way :Curved: I will need it mainly for portraits. Often idoors. Some nature. If you have any of these lenses can you tell me the pros and cons? If possible could you show me a good sample?
