Some of my first photos this March, the first two on a sunny day, the rest on a cloudy one, no mist or fog on either one, just a little bit of spherical aberration at 4.5/85mm.
Note the highlight bokeh on the golden onions of the cathedral in the background:

Coating has nothing to do with it, it is just the effect of very liberal amount of intensional spherical aberration.

No, not a meniscus, a detuned triplet. Thanks.

Thanks. Yes, but must be used in moderation.

No offense taken, I know many people aren't keen on this kind of photography. Anyway, this lens is sharp enough for most real-life photography - at another setting It is perhaps my most versatile lens, capable of producing anything between the above soft focus, soft bokeh shots and something like this, taken with the same lens on the same camera:
Of course, it is impossible to judge the resolution on the basis of a small image like that, you really must take a look at the original, see http://galactinus.net/vilva/retro/eos350d_radionar_files/r2984_100.jpg. The photo is taken with an uncoated, 1938 Schneider-Kreuznach Radionar 4.5/105 without a lens shade. The soft shots were taken with the front cell adjusted to focus at 0.5m and using an external focusing mechanism, which drops the FL to something like 85mm and produces a prodigious amount of spherical aberration - of course not suitable for all targets or purposes but still useful, often when a "normal" shot would be nothing special.
It is, of course, possible to use any intermediate setting between these two extremes, which is very useful, especially for portraiture. Most of the old, fine, adjustable softness portrait lenses are definitely too long for dSLR use and also rather expensive, even on eBay. This Radionar setup is a poor man's solution for many situations, a lens which I use both on a 350D and a 5D. With some PP, softness and flare can be considerably reduced at focus, giving even more possibilities for creativity.
With a tool like this, it is necessary to take a lot of photos in order to chart the possibilities and limitations, a lot of work, a lot of waste, just like with any artist's tool. It's very educating and most certainly great fun.
