DESU, if your lens doesn't feature 5 or 10 aperture blades, I don't even LOOK at it. 12 blades is deemed acceptable. If your movie or documentary feature those, then I know the guys behind it are connoisseurs, men of culture with the finest taste.
If it's an 9 or 11 blades vomit-inducing abomination, into the trash it goes.
