might be a stupid suggestion, but I se that no one has brought it up.

The older lux'es has closest focussing distance of 1m, while newer have 0.7. the Nokton has 0.9.

just thought I'd point it out, since focussing distance greatly affects depth of field

I know this thread is getting old, but I'm also very interested in finding a Noctilux alternative. This far I haven't really found any.

The three reasons (there are probably several more) for wanting a Noctilux is that it is fast, it can produce incredibly shallow depth of field, and the typical noctilux look with light fall off in the edges (vignetting)

As said before, the difference between f1.2 and f1 isn't that big when it comes to what shutter you can achieve. It is however greater when it comes to depth of field. the problem with most lenses suggested here is that they won't be able to reproduce the dof of a noctilux because the closest focussing distance is 1m. If you had a f1.2 lens that could focus to aboud 0.8, it would reproduce the same dof. This issue points towards getting a SLR where close focussing is much nearer. Of course going nearer your subjects means that they'll get bigger on the picture. As for vignetting, I'd say get a hood that's to long for the focal length.

"I will note that at least from evidence on flickr, users of the CV 50/1.5 Nokton seem to be thinking of it as a "cheap 50" rather than as a "fast 50"; that is, they don't seem to be trying to use it as they would a Noct, wide open in situations where bokeh is an intentional part of the image."

I have this very lens, and close focussing is the only minus I can find. With a 50mm f1.5 lens that doesn't focus nearer than 0.9m it's hard to get the depth of field one wants, It also makes it quite useless for up close portraits. I have tried though ( ).

I'd be really interested if anyone had an alternative that isn't mentioned in this thread.
