This lens was fitted to the later versions of CP16R 16mm film news cameras of a bygone time.
It was a standard 16mm format lens. Its task was to have a long reach but also the versatility of a wide view. There were some compromises. The focus breathing is cruelbad compared to modern lenses. There was also a vignette on focus closer than 1.5 metres in the wider end of the zoom range.
On the lens barrel is a red line which marks where the vignette will occur. On a Super16mm-capable camera or the SI2K, The vignette intrusion on the wider image occurs from about 2.5metres. The lens is not the sharpest example of Angenieux 16mm zooms. It returns 67 sharpness points on the SI2K across a fairly wide aperture range. I was not able to identify a distinct sweet spot from the sharpness numbers. The last stop to wide-open yields a soggy and flarey image on this specimen.
For a specific project for which the long zoom range was required, I acquired a PL-Mount designed by Ken Hale at Whitehouse AV. On fitting the Angenieux 10mm - 150mm PL-Mount, due to unavoidable necessities in the mount design, there is a likely clearance problem with the aperture control ring.
Due to variance in the lenses themselves, some iris control rings clear the front face of the new PL-Mount. Others hang too far rearwards and interfere with the mount. The iris control rings have to be taken off the lens body and the rear overhang either skimmed down on a lathe or hand dressed until clearance is achieved.
Ken also does a PL Mount for the 16mm 10-100 old style T*3 Zeiss lens in Arri B 6 hole fixture for the mount.
He has been fighting an illness for a fairly long stretch and has started coming good only recently. A few customers have apparently been a bit disappointed with him over delays which were caused by illness. I received my mount in Australia in short time, six days from payment.
I had my mount sent out to me in Australia for self-fitting onto and collimation of an existing lens I have here, a tyranny of distance thing and the need was urgent. I would recommend residents in the US and Canada send their lenses in for fitting and collimation. FOOTNOTE: Repeating, this lens is suitable for 2K imaging only and not through its entire zoom range at focus on subjects closer than 2.5metres.
