  1. Hello Ian, Thanks for the replay - Unfortunately frame rate (29.97) is not the issue here. Also - as mentioned in my initial post changing my shutter up or down made the problem worse. Shutter speed in this case is being used to eliminate horizontal banding caused from flo-tubes running on 60hz power. Regardless of my frame rate (I am actually shooting 24fps, or 23.976 to those who like specifics) - setting my shutter to 60 should eliminate the the scrolling line of flo tubes as it does on all of the various pro cams i shoot with. The link you shared however is helpful as that guy seems to be experiencing issues similar to mine. It leads me to believe the problem is with the shutter of the 7D being inaccurate. As I haven't heard many rumblings about this from others I also suspect that perhaps it is only an issue with my camera, a certain production/manufacturing cycle of the camera or is an inherent problem with the camera that just hasn't caused others much grief. I did purchase mine after the tsunami mind you..-- traces of radiation fluctuating the electronics? that would be interesting..
  2. I believe the HDMI port on the 5D is 1080 until you hit record - then it scales down to SD - so if you are planning shots rather than run/gun, check focus before you roll. Also, most small format HDMI monitors are only pumping out about 800x600.
  3. Shutter is at 60 because I am in N. America and shooting in an environment with lots of fluorescent tubes (with 60Hz power running through them.) Any other shutter speed (save a multiple of 60) would create scrolling lines through my footage. My shutter being at 60 is not the issue here.. My issue is whether or not the shutter speed on the 7D is accurate - as when set to 60, shooting around fluro tubes I am intermittently still seeing lines through my footage.
  4. I have the feeling my shutter is inaccurate on my 7D. I'm wondering if this is a common issue, or should I have my 7D body sent in for repair. The last few times I've shot near fluorescent lights I am getting horizontal banding lines typical of shooting with the wrong shutter speed through my frame even though my shutter is at 60 - dialling the shutter up or down only makes the banding worse. The first few times I saw it I figured it was due to an issue with the ballast of the light fixture or the tube itself.. But I have been seeing the issue far too often for comfort. Also, powering my camera off, then on again at times seemingly softens, or worsens the problem. Anyone else seeing issues with their 7D shooting @ shutter 60 near tubes?
  5. SmallHD DP6 has worked great for me. Fantastic little monitor. http://www.smallhd.com/Products/DP6.html
