    The Canon FD f/1.2 85mm L lens has 8 blades and I think the FD 1.2/50mm L lens also has 8 blades. I have the 85mm and it's a wonderful lens.

    Dave, That's certainly a very nice selection of Zuiko lenses and thanks for taking the time to check them out. I will have to see if I have an 8 bladed lens to see how the geometry will affect this.

    Newt & ffg, In looking at some superfast (f1.2) lenses, I was really disappointed in the lower blade count.

    The current Zeiss SLR lenses in ZS (M42), ZE (EOS), and ZF (Nikon) mounts qualify. My 35/2 ZS (M42 mount) and the 85/1.4 ZE (EOS mount) have 9 blades, and I suspect the others do as well. They're all manual focus lenses.

    I like the solidity of a lens with more blades and the nice round aperture, but that said, the optical design is a more important factor in the rendering of the out of focus portion of the image, and a lens with fewer blades stops down faster, reducing shutter lag.

    David, As photographers, we have been trained to use compromises to our advantage and certainly there are tradeoffs in lens selections. For instance in the picture below, once I noticed the not so perfectly round OOF highlights, it became distracting. I have heard of these bokeh monster lenses and would like to try them out. No doubt they will be exceptional in this characteristic, but there will probably be some other thing to consider after using them

    In that image, though, the appearance of the out of focus highlights in the background (the foreground is different) isn't only caused by the shape of the aperture. If it had a perfectly round aperture you might still find it distracting, since the out-of-focus highlights are brighter at the edges than they are at the center, though not extremely so I would say. I've seen worse cases. It's more important, I think, that the center of the highlight points be brighter than the edges, and then the shape won't matter as much, and that's an optical design issue.

    I bought quite a few that fit your request but aquired a Spiratone TC 135 2.8 (18 blades) and was plensently surprised. In fact, there's one on ebay for right now $35 BIN ..

    I agree. My Super-Angulon f/3.4 21mm in Leica M mount has four blades, and delivers Leica quality images.

    The 58/2 M42-mount Carl Zeiss Jena Biotar in this group had lots of blades--maybe 17 or 18--lousy bokeh in my opinion:

    Also, I forgot to note, there are Rounded and Straight blades, many manufactures make either, or both. Must research production histories though.
