FS7: Sony fs7 vignetting with speedbooster and canon ef 24-70

[awhitley]

Anyone have a problem with a vignette on the wide end of the 24-70 using a speedster ultra? I have noticed it a couple of times and I found that if I reboot the camera it goes away. Very strange, maybe something in the electronics of the speedbooster?

Never noticed this. I do have other problems like aperture some times not working and having to re-boot

You need to switch off when changing lenses with electronic aperture otherwise all sorts off wonky stuff can happen.
