5D MKIII magic lantern 3x crop= 11.6mm sensor width. adapting s16 lenses (meteor 5-1 or other m42 mount ?)

[Johanan Pandone]

Hey guys,

I was doing some math the other day and realized that when shooting Raw video in the 3x crop mode on my 5D the active sensor area is very close to 16mm format. I'd like to try an m42 version of the krasnogorsk meteor 5-1 zoom since m42 is easily adapted to EF mount. Are there any other 16mm cine zooms that could be adapted in this way?

Watch out for the rear element hitting the mirror.

You can convert Arri standard and Bayonet to EF (might have similar issues with the rear element) but those lenses are expensive compared with an 11-16mm Tokina or whatever would probably work just about as well. Also might have issues with mirror clearance.

There's very limited options for zoom lenses with more than 2-3x zoom range. That's why I'd like to explore this further.
