Good points John but surely if it isn't measured and one needs to be in control of this and other unmeasured aspects of a lens performance the only way to do that is to use the lenses oneself rather than rely on the wishy-washy and simplistic assessments of a vague magazine report: as has been reported the out of focus rendering of any lens is affected not only by the specific and unmeasured 'bokeh' qualities but also focussing distance to subject (or non subject rather), light conditions, aperture, and other factors. These are conditions best judged in a reflex finder in the first place and in the second are so highly specific to a particular working style and situation as to make assessments of the out of focus image being 'nice' or 'harsh' misleading. What is nice bokeh for one situation may be less nice for another and depends on taste as much as any of the other factors. Some people think the doughnut shape of mirror lens bokeh is cool, others find it nauseating but that is IMHO purely a matter of taste and the skill of the photographer to use it creatively. Some people even create their own custom bokeh by using cutouts of stars, smiley faces or whatever to make unusual highlight shapes in the bright highlights: fine. I don't think many if any people carry a mirror lens and a regular long focus lens to explore the bokeh possibilities of both for practical shooting let alone lenses with more subtle distinctions. In any case the main concern of the bokeh crowd is on a much subtler level: the 35/2 vs 35/2 ASPH for example. Magazine articles and even books may use images by different bokeh lenses to illustrate the point but that is incidental to the main image making activity not the preoccupation of the photographer. Doug has experienced specific bokeh problems with some lenses and situations. Does that mean they are bad lenses? I think not but I am sure others have already discounted them even though their usage would be likely very different due to what is I believe an exaggerated fear of 'bad bokeh'. Is Doug wrong or imagining things? Of course not. You (and I) seem have learned how our lenses work by using them: others seek guidance through the inadequate source of jargonising pseudo-technical writers with whose guidance we would all probably be using the latest Sigma UltraApoMacroNeoDefocusZenMegaOptic rather than taking photos. I think pictures speak louder than words and I do not find bokeh to be an issue in your photos - even when I am looking for it - so I guess you have put that behind you. BTW is anyone you know of in the film world interested in bokeh? It must have more relevance there: those double edged blurred things in the background moving about...
