Oreston 50/1.8 with a triangular aperture

Is this lens modded or is the aperture actually like this, because I can't find any info about this "three blade" version

Are there 6 blades inside of it, and 3 of em might be customized (cut)?

That's what I've thought...

I can confirm... got one like that and it's a lot of fun:

There are also Helios-44 lenses out there with triangular aperture (and other shapes as well). That being said, I prefer to use lenses which have a triangular/square/star-shaped aperture in their original state overall, because the resulting shapes often look a little bit better. It might also depend on the quality of the mod though...
