See the video below for ARRI format coverage of each lens in our Cooke Mini S4/i set.
You'll see that all lenses in the set have an image circle large enough to cover the super 35mm open gate format (Alexa 35 and Alexa Mini open gate). Only the 75mm and 100mm lenses cover the full LF open gate format, but the 32mm and longer cover the 3.8K LF 16:9 format.
The table below summarises coverage of the lenses in our set.
| Focal Length | LF Open Gate | 4.3K LF 16:9 | 3.8K LF 16:9 | S35 Open Gate |
18mm | No | No | No | Yes |
25mm | No | No | No | Yes |
32mm | No | No | Yes | Yes |
50mm | No | No | Yes | Yes |
75mm | Very close - vignetting. | Yes | Yes | Yes |
100mm | Yes - some vignetting. | Yes | Yes | Yes |
