Recommendations for lenses with more then 6 iris blades
I would like to get some manual focus lenses in various focal lengths but I want them to have more then 6 blades. More often then not this bit of info is left off descriptions so I wanted to ask if you have or know of any such lenses. I have the following mounts that I can use them with - Canon, Konica, Minolta, Nikon, Olympus, Pentax (M42 & K) & Yashica/Contax. TIA.

Apparently the Canon EF 50mm f/1.4 has 8 blades.

Sorry but I am only looking for older manual focus lenses because I prefer the typical build quality to match my kinda cameras.
-
Perhaps you could consider trying RF cameras?
When you don't need the speed in stopping down you usually have a lot more blades.
Take a look at Leica lenses and you will see what I mean.

Nikon 45/2.8 Ai-P has 7 blades.

I think Russian Tair 11A (135mm f2.8) has something close to 20 blades.
Jupiter 9 (85mm f2) has ... 15 blades ...
They are M42 mount.
Tair 11A is one of the best Russian lenses I had.
FYI, if you look for old lenses in pre-set aperture, they usually have too many blades to count ...

Jesper, I have been trying to get into RF's but the time isn't right. Are you saying that slower lenses have more blades in general or Leica specifically?
20 blades as eSPhotos recommended has piqued my curiosity. Other examples by Thomas for the 85mm Jupiter or Helios too.
Here are a couple of examples that clearly show my interest regarding the different results from a 10 (top) and 7 (bottom) bladed lens . . .

Les,
I looked at the lenses which I own and counted the blades.
The following Olympus OM Zuiko lenses have six blades: 18mm f3.5, 21mm f2, 35mm f2, 40mm f2, 50mm f1.8, and 50mm f2 Macro.
The following Olympus OM Zuiko lenses have eight blades: 24mm f2, 50mm f1.4, 55mm f1.2, 85mm f2, 135mm f2.8, 180mm f2.8, 300mm f4.5, 400mm f6.3, and 600mm f6.5.
The 100mm f2 ED Zuiko and 250mm EDIF Zuiko both have nine blades.

Nikkor 50mm 1.2 ais = 9 blades
Canon 50mm 1.2 RF = 12 blades
Any ol enlarger lens 80mm or longer on a bellows = 16-25 or more blades!
