Hi!
The Canon FL 35 2.5 has a hexagonal aperture. Not star-shaped, but kind of pretty anyway. I'll find an odd-shaped one to show. Here's the Canon:

When there are bright OOF highlights, of course. You'll get star-shaped blur discs, just like you get hexagons/octagons/etc. with most regular manual lenses. When there are no strong highlights in the bokeh, the aperture shape will make very little difference.

This one has a star-shaped aperture - or at least its a round aperture with "points"
The shape does show in out of focus highlights sometimes - one of the sample shots has a perfect case.

Probably only at f/2 and f/2.8. I think that all Contax lenses that can display a pronounced ninja star (most of the faster AE lenses, 35/1.4, 50/1.4, 85/1.4 etc.) only do so at one or two aperture settings. |
