However, my personal experience is that low-key pictures with an Imagon are a good bit harder to make work than those in high or moderately high key.
There is quite a lot of written material on the Imagon lens (on http://www.cameraeccentric.com/info.html there are two articles and a brochure). One of the things written is that more direct lightning is prefered to soft lights. I.e. much "tougher" light than what is normal for portraiture.
