16mm LENS TEST/LOS ANGELES

PostFri Jan 11, 2013 11:54 am

Waiitng on my BMCC EF. Have almost everything to it already.
Rig, power, cards, filters etc.

Just ordered from ebay 16mm angenieux 9.5-57mm.
It is going to come in a week. So I'm looking for anyone who ones BMCC around LA.
Just to make a quick test to see how much of censor it covers and can I reach infinity?

Hope to find someone! Thanks!

I'm curious if that will cover the sensor.
Would be fantastic, since there is a ton of great and cheap 16mm glass out there.

We have quite a discussion going on, regarding that issue in the moment.

Also Dom Jeager made a nice list

This is a partial list of S16 lens image circles that I've measured, using a projected reticle like Matt. I haven't found any focal lengths under 16mm that would cover the Black Magic sensor (~18mm image circle).

Optex 5.5 ~15 mm
Kinoptic 5.7 ~14.5 mm
Angenieux 5.9 ~14 mm
Zeiss Mk3 9.5 ~14.5 mm
Zeiss Mk3 12 ~16.5 mm
Zeiss Mk3 16 ~19 mm
Kowa Ultra T 9 ~14 mm
Kowa Ultra T 12.5 ~15.5 mm
Kowa Ultra T 16 ~16 mm
Switar 10 ~14.5 mm
Switar 25 ~15 mm
Cooke SK4 6 ~16 mm
Cooke SK4 9.5 ~16 mm
Cooke SK4 12 ~16mm

Out of that list, Zeiss Super Speeds are the only option, with the 16 (and 25) covering. From Matt's description it sounds like the Zeiss Ultra 16s all have an image circle of ~16mm, similar to the Cooke SK4s.

With zooms, you can get partial coverage at the long end, and go a bit wider if you don't stop down past T8:

Zeiss 11-110 covers from 50-110
Canon 11-165 covers from 50-165
Canon 8-64 covers from 30-64
Angenieux 7-81 covers from 25-81
Canon 7-63 covers from 20-63

It's possible to increase the image circle of a lens with a focal length extender, which is basically how old Standard 16 lenses were converted to S16. I tested a Zeiss 10-100 with a doubler for example and found that it would cover the Black Magic sensor through the whole range (20-200).


Cant wait to see some real world results over grey theory.

Shane just confirmed that the lens he is using covers the sensor.

did he confirm that the lens covers the sensor at any focal distance?

And it also depends what aspect ratio you are shooting. 2.40 gives a little bit more room, by cutting ages.
