Will Gemini cover. . .

[Stephen Pruitt]

. . . the Tokina 11-16 and the Sigma Art f1.8 18-35 without vignetting?

Thanks.

Stephen Gemini is the EXACT same size (give or take) as Dragon 6K and Helium 8K. So same coverage issues arise.

Tokina 11-16 should cover yes. The Sigma 18-35 should cover starting at 21mm.

My 11-16 vignettes at 11mm on 8K FF Helium (33.80mm image circle). If I'm wide open 12mm usually clears it up. Stopping down, I need to go to like 13mm.

I imagine it'd be just every-so-slightly worse on Gemini at 5K FF (34.73mm image circle). And maybe a little more if you're shooting the full sensor 5K 1.7:1 (35.61mm image circle) or doing a 16:9 extraction out of that (35.25mm image circle). Shooting in-camera 5K HD though, you should be fine (33.04mm image circle).

11-16 vignettes on gemini at 5k. It covers past 12-14 depending on how much coverage you consider acceptable. 4k on Gemini is pretty much s35 and all of your lenses should cover there.

So you're telling me that our go-to lens (the Sigma Art 18-35) is a no-go? That's a total bummer. Might keep me from upgrading right there. That lens is amazing.

From 21mm you should be OK.

Thanks for the info gents. Unrelated to my original question, but still important to our decision, is how are you getting audio into the camera??? It is my understanding that it has no audio inputs.

Just use an A-Box.

Or get the studio module.

[Stephen Pruitt]

An A-box won't provide phantom power. Does the camera?

Having just tested this myself, unfortunately the Sigma 18-35 Art vignettes the whole way through.

At 18mm you can see the whole image circle but at 35mm it looks just about acceptable/natural. Next time I get a chance I'll share some samples.
