[Greg Nosaty] “What make of intervalometer do you use?”
Vello ShutterBoss, terminated by a sub-mini plug. Is the same model of ShutterBoss meant to work with both the 60D and the 5D Mark II?
I just made three quick tests: I set the VelloBoss to run a series of 10 exposures at 1-second intervals on my 60D, with various settings. The bottom line is that shooting RAW+, or using Image Review, seemed to result in problems.
Camera for Tests 1 and 2 was set to Manual exposure, lens was set to AutoFocus. Image Review was set to 2 seconds.
1. When I shot RAW+large JPEG, I got 9 exposures.
2. When I turned off RAW and shot only large JPEG, I got all ten.
3. I turned off Image Review, set the lens to manual focus, shot RAW+large JPEG, and got all ten exposures. BUT – I noticed that when I turned the camera off, about 15 seconds after the series was shot, the camera took perhaps 30 seconds to record the images it had just taken. So if you shoot RAW+, a longer series than just ten images might not work.
fwiw, I use JPEG only, and tend to use smaller JPEG settings, when shooting timelapse, although I realize that a large image is useful for zooming and reframing.
