    Bokeh is a designed amalgam of uncorrected abberations. Creating a lens with good bokeh is an art.

    Since 1969 I've mostly shot with Leica lenses not particularly known for being super sharp. I, seriously, never knew what bad bokeh was until I bought a Nikon in the mid '90s.

    My favorite "good bokeh" lenses and the year I bought them, since I don't know which version they were:
    35mm Summicron M (1972)
    50mm Noctilux M (1975)
    50mm Summilux M (2001) (Superb at f1.4)
    90mm Summicron R (1970) (my all time favorite portrait lens)
    140mm f2.8 Contax for 645 format (1999)
    300mm f5.6 Apo-Symmar which I use with 5x7 film, very good out of focus areas at f8, used for portraits.

    If you use lenses with good bokeh, you'll never notice. If you use lenses with bad bokeh, you will.
    Take care,
    Tom

    A lens I dearly regret selling was the first RF 35mm F1.4 Summicron. I liked the wide-open charactristics. A good lens is not always an optically perfect one.

    Sorry, I don't have any scans to show. It may not affect all MF Tessar lenses. Here's an earlier discussion of the subject:

    I think there's some variation among planars. The lousy Biotar I mentioned above is a planar, but so is the Voigtlander 50/2.0 Ultron, which has great bokeh (no specular highlights in the OOF area here, but nice smooth lines)--



    I have a Zeiss 135/3.5 Planar for 4x5", which is usually pretty well behaved (also no obvious specular highlights in this one, but again, no double lines or other clutter)--

    I don't seem to have anything conveniently scanned with the Bronica-Nikkor 75/2.8, which is another planar-type, but offhand, it strikes me as a lens with neutral bokeh. I think I'd say the same for the 105/2.8 Xenotar, which is another planar-type.

    None of them have backgrounds that would reveal it at such small magnification.

    There are a couple that have some good lines in the background that would be busier with poor bokeh, and the OOF highlights in this one seem to fade nicely--

    Rummaging around in his portfolio, I found more shots with this camera and a picture of the camera itself, which shows a Zeiss Tessar as the taking lens. I'd say he got a good one.

    Tim, did you get that fluid at a company called 419 perhaps? I've heard of them before somewhere, although I can't quite recall where...

    Polygons ain't what bo-keh's about.
    As an example a lens with bad bo-keh may take an out of focus twig and split it in two
