Looking for some light reading this weekend? Canon released the â€œWhite Paperâ€ on the 1D Mark IV. The white paper is filled with detailed info on the 1D Mark IV.Â The HD video capture section is in chapter three starting on page twenty-six. Â Automatic gain will still be the main audio issue with the 1D Mark IV, however Canon seems to be addressing some of the audio problems.
â€œThere is also a feature to automatically reduce aperture drive noise in video clips recorded with the built-in micro- phone, a feature thatâ€™s available for the first time in an EOS Digital SLR. However, the built-in microphone may still pick up noise from operating the camera dials, lens, Image Stabilizer, AF motor and so forth.â€
