The new Sigma seems better than the 24... i need to buy a 20 to shoot interiors, i really don't need to shoot wide open, and i don't care about bokeh... i need a large Dof, and i need to correct distorsion !
The nikon may be less prone to flare because the front element isn't as prominent as on the sigma ?!
I don't use filters, and i will shoot at f8 to f11 on a tripod using live view most of the time on a D800/D810.
Shall i go for nikon or sigma this time ?
PS : i allready have the 35 and the 50 art...
