Hey Guys,

Back when the 5D first got the manual control update I briefly tested it under HMIs in Toronto. There was a pretty bad issue with the sensor reading those gross bars refreshing across the screen. I was wondering if anyone has found a way around this. I tried shooting at all the shutter speeds and nothing seemed to get rid of this. Mind you this was a little while ago and I can't quite remember what the best option was, but I know I was not satisfied with the end result. If anyone had some information on how to go about shooting under HMIs I would love to hear it as I have a project coming up that really would benefit from HMIs.
Thanks in advance,

Ian Carleton

Were they on flicker free or magnetic ballasts. CMOS sensors don't handle magnetic hmi well at all.

It was a little while ago but I fairly sure we tried the camera with both types. We were testing at a rental house so were able to try some different options. Since im not certain im curious if anyone else has had any success with this.
