Hello,

I just saw a Dutch tv series that was shot on super16 called Waltz. When I wasn't enjoying the more important things, like the very good drama and camerawork, I noticed the out-of-focus highlights were triangular most of the time. I was just wondering what you can say about the types of lenses that could have been used on this show. I know they use superspeeds a lot here, but I read they have a hexagonal iris, or do they?
Nothing too important, just wondering.

Thanks

Negative.

MK II Superspeeds for 16mm have three iris blades which causes the triangular bokeh. The MK I and MK III's have more blades which cause a more spherical bokeh.

Hi Nathan,


Are you sure about the MK IIIs? I have a set I purchased from Visual Products and had checked by Pauls Duclos. They both told me the lenses I have are Mk IIIs, and they definitely have the 3-bladed iris. Is there any way to verify the Mk series with serial #s or some other identifying characteristics?
