I have been working on some startrails/planetrails shots this week and have noticed something very odd about long exposures and high speed shooting mode on my 7D.
The problem is that even though I have high speed continuous shooting turned ON, I can hear a definite gap between exposures. I'm hearing at least 1/2 second gap between exposures where I should be looking at around 1/8 second (high speed continious shooting mode should yeild up to 8 frames per second on the 7D). There is also a noticable gap in the plane trails caused by this lag between exposures.
I have searched through the manual and turned off those features that will affect high speed continuous shooting performance:
- Long exposure noise reduction
- High ISO noise reduction
and still no improvemement.
I've tried RAW mode and JPEG mode and there is no difference.
Am I missing something?
