Whew, I'm glad we're getting back on track with this thread -- seemed as if things were getting a bit acrid for a while (although as a result of a legitimate misunderstanding over whether the original image was being posted for critique or to illustrate the optical properties of the lens.)
Just as a general observation, it's worth noting that people usually use an ultra-speed lens such as the Noctilux for one of two completely different reasons: either for photographing in very low light (I fall into that category) or for creating limited depth-of-field effects. We've had several good example pictures and discussions in the thread of the limited DOF characteristics; like Tuolumne, I'd be interested in seeing more examples of its use in low-light work.
This is also a good opportunity to share observations and advice as well as images. For example, although I don't own a Noctilux, I use a number of other lenses with very limited DOF for theater shots (Canon 50/0.95, C-V 35/1.2, Canon 85/1.5, Canon 100/2) so I'd like to assure Tuolumne that you can get better at managing this with practice.
One advantage you have in most theatrical shooting is that the action has been planned by a director rather than being spontaneous, so significant moments are likely to happen at specific locations rather than randomly. By studying the way the show is blocked, you can anticipate where the important locations will be, and make sure you shoot only when the performers are within the zone of best focus, based on your knowledge of the characteristics of your lens.
To pick a simple example, I often have to photograph lecturers at a museum, and the only way to do it is with my 100mm f/2 Canon lens on my R-D 1. This beast actually has less total DOF than a 50mm f/1 lens, so plane of focus could be a problem. However, I've learned that if I focus on the microphone stand on the speaker's podium, then wait until the speaker leans forward to speak into the microphone, I get both the best lighting (bouncing up off his/her lecture notes) and can be sure that the speaker's face will be within the plane of best focus.
