16mm lenses

[JustinColeman@mac.com]

Hi,

I just wondered if someone could help with a gap in my brain...

I've got an Angeniuex 12-120mm lens from my Arri 16BL 16mm camera and I wondered which of the new scarlets is best for it, assuming that I need an adaptor but want to use the lens as wide as was originally intended. Ive seen C-mount lenses and Arri PL mount lenses but not sure how this affects me.

Many thanks for all help.

I would imagine the 2/3" interchangeable. Isn't 2/3" supposed to be close to 16mm?

2/3 scarlet with the interchangeable lens option should work fine for that.

Yup, the sensor size on the interchangable lens 2/3" Scarlet (10.1x5.35mm) ist quite close to Super16 (12,35 x 7,42 mm), so with a C mount on your "brain", most 16mm lenses should work fine.
I've been wondering about the Arri PL mount though, since it's used in a wide variety of modern 16mm lenses, including the new Zeiss Super Primes for 16mm... Is this PL mount different from the "standard" PL mount, or would you just use the larger mount (like you can screw on the S35 Scarlet) for a lens with a smaller image circle?

pl mounts for modern 16mm lenses and 35mm lenses are the same. sometimes there is an issue with the back end of the mirror of a 35mm camera potentially hitting the rear element of a 16mm lenses if you mistakenly put a 16mm pl mount onto a 35mm camera.

Standard 16mm aperture is 10.26mm x 7.49mm. Standard 16mm lenses will match very nicely with 2/3" Scarlet. C-mount is the easiest way to go here.

Hey everyone!
For those looking to purchase 16mm lenses for Scarlet, could someone please explain how one could avoid purchasing a Security Camera lens??
I just need clarification. Thanks!

Look for lenses that are listed for Bolex, ARRIS, Beaulieux, Aaton, Eclair ACL, 16mm cameras. Shop cine equipment dealers. Web search for 16mm cine lenses by brand name Angenieux, Zeiss, Cooke, Schneider, Century.

Thank you so much

I posted this in the lens mount thread, but it probably is more useful here.

Here is a link to sample images shot on Arri 16S with various 16mm prime and zoom lenses. Should give you an idea of what these can do on Scarlet.

Classic Angenieux 12-120 f2.2 c-mount. The crank is the zoom handle. I have one of these, but with an optical finder takeoff, so f2.8.



You have to be careful shopping for old c-mount Angenieux 12-120's. A lot of them were used on 16mm news cameras before ENG cams existed, hence the ready availability and low prices. But the news cam lenses got a lot of rough use and often were not well maintained. I think this is the primary reason why they have an iffy reputation on the used market. These lenses are pushing 40 years plus and most will need a comprehensive overhaul, at least a complete disassembly for cleaning, lubing, and collimating. There is often wear in the zoom mechanism. Cost can range from several hundred dollars to well over a thousand. Get an evaluation by a good cine lens optical shop before buying one.
But one of these in primo condition will produce beautiful images and they are easily adapted for external focus and zoom controls. They are fast too F2.2, but you give up some contrast and sharpness at the lowest settings.

The later model T-stop rated ones with HC coatings are much better, but their prices reflect it. The shorter 9-57 has a good rep. The Zeiss 10-100's and Cooke 8-54's have a better reputation but also cost a lot more.
