The depth of field of any f1.2 lens is going to be shallow for things like portraits.The depth of field is too shallow at f/1.2 to be usable in most situations and becomes a gimmick as with similar wide angle lenses. When I used a 24mm f/1.4 to shoot weddings I avoided the f/1.4 aperture for the most part as the DOF meant I could not have both the bride and the groom in focus in the same image. I used it at f/2.0 or smaller apertures for that reason.
I used a Sigma 35mm f/1.4 as my Nikon digital cameras exhibited extreme levels of noise at ISO greater than 640 and the faster glass helped the autofocus system in low light situations. Faster than f/1.4 would have provide not benefit and a reduced DOF was the last thing I wanted for the images for my clients.
Because its a 35mm lens this shouldn't really be a problem for most people and you can always stop down if you are struggling.
F1.2 would be a great street lens if it wasn't so big and heavy like Nikons' other fast lenses......
