Dragons and Zooms

Cooke 18-100 should be fine at 5.5k. Some one bring your Dragon by and we'll test it with my Cooke

Phil's tests indicate

Angenieux Optimo 19.5-94mm T2.6
@19.5 - Portholes at 6K FF, 6K WS slightly but covers 6K HD with vignette
@30 - soft vignette at 6K FF
@94 - Clean 6K FF

"Angenieux 19.5-95 cover entire range at 6K HD. Killer range - awesome lens for Dragon."

Do you guys have different testing regimes or could there be a variance in the two lenses you tested?

He's saying it covers at 6K HD and so am I. I'm just stating it vignettes at 6K HD, which it does.

The way this pretty much works in diagonal coverage is going from the largest format to the smallest format. With Epic Dragon this works out to:

- 6K FF
- 6K 2:1
- 6K WS
- 6K HD

And so on for each sub-format/resolution.

So for example, if you have a lens that covers 6K WS, it covers 6K HD and everything below that.
