50mm with more blades

[sinner79]

Which ones? Could you tell me 50mm lens with more than 6 blades?
Thanks.

Good question. You probably asking of later F1.4 or F1.7 or F1.8 lenses? I am sure some auto versions have 8 (YASHICA ML 1.4/50mm) or 9 blades but more?

[IAZA]

Pancolart is right, you should mentione what f?
for example, f2 Helios 44-3 8 blades
CZ tessar 50/2,8 variant, I saw 12 blades

I about fell off my chair when I counted the blades on my Schneider Xenon 50/1.9 for Exakta. There are 20!

The older lenses tend to have more blades. My Auto Rokkor Minolta 58/1.4 has 8, whereas the MC Rokkor 58/1.4 has 6.
