This is a rather rare lens in C mount for 16mm film camera. While the Meyer Trioplan 100mm f2.8 lens is famous for its “bubble bokeh” I honestly believe that this Ilex lens bests it in terms of bokeh. The circles are finer, giving a more complex bokeh, while still maintaining the look. In terms of sharpness this lens is mediocre, and in the contrast department as well, but I really do love the look.
