When I look at the aperture in the menu it is flashing and changing randomly. I am using a 200mm canon L prime. Any help?

I also had the same issue on a 24-105mm L Zoom.

Seems Jarred said to reset and reboot: here (http://www.reduser.net/forum/showthread.php?67952-Epic-and-Scarlet-Build-2.0.5-released.&p=886823&highlight=#post886823)

Tried all of that. Thanks for the link, but didn't solve the problem:( I emailed support but no solution yet.

Slightly off topic: Is there a list somewhere that shows what Canon mount lens's are known to work ?
I know the 3rd party lens makers sometimes had firmware issues, I worry about that being a problem as well.
Maybe we can start a list online that at a minimum shows a 'ok' on a lens functioning with aperture and focus motor?

Jarred posted a list at one point. I am not sure where it is though.

Will, have you tried the re-discover hardware option?

Thanks Brian.
I bought two Sigma 8-16mm 's and two Tamron 17-50's at Samies , I guess I'll see how they work soon enough!

Update:
I've tested the Sigma 8-16, and the Scarlet can change the f-stop and move the focus ring.
I'm a bit disappointed in the focus finding algorithm however. Needs work.

Since neither lens has been programmed into the mount as yet, I don't think you can really judge much from your experience. From what I have read here about people's experiences with lenses that aren't yet on "the list," you may be lucky they work at all.
