See the video below for ARRI format coverage of each lens in our Leitz (originally branded Leica) Summicron-C set.
Only the 75mm and 100mm lenses cover the full LF open gate format, but the 35mm and longer cover the 4.3K LF 16:9 format (if the vignetting of the 35mm is acceptable to you). All lenses 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 | Alexa 35/Mini Open Gate |
18mm | No | No | Yes | Yes |
25mm | No | No | Yes | Yes |
35mm | No | Yes - vignetting. | Yes | Yes |
50mm | No | Yes | Yes | Yes |
75mm | Yes | Yes | Yes | Yes |
100mm | Yes | Yes | Yes | Yes |
