Re: fp + M42 Chinon 55/1.4

The swirl is by design. It's the same as any other Tomioka 55/1.4 lens.

You can see balsam separation effect on the bokeh circles here:

Inside each bokeh circle there is small black outline. Its shape is exactly how balsam separation line goes inside the lens. What's interesting, the bigger the bokeh circle, the less effect is observed. When circles are small, the defect is much more noticeable, it becomes more "focused".
