Well if I shoot video I prefer the shallof DOF look and if shooting outdoors I would definately be using 1.4 and a hood would be essential.
Then don't go all the way down to 28mm opening. 30.5mm opening is good, no vignetting even at F/1.4 and for a (full-frame) film camera:




No vignetting here:




30.5mm opening is good even for 21mm focal length (DA 40mm and DA 21mm with a double lens mount cap):

I actually said out loud to myself "What in the hell is that??" here at the computer when I saw that. It took me a few seconds to realize what it was, before reading what you wrote. Very interesting looking! Do you know where they're for sale? I might have some small primes that could use just such a treatment.
