The AE adjustment order is ISO (gain), followed by shutter speed, followed by aperture.
The idea behind this is that changing the ISO is an electronic function which does not generate audible camera noise, so it is prioritized as the first parameter to be adjusted by the AE function. Shutter speed is next, but HD video recording in the 5D Mk. II is limited to a narrow shutter speed range of just 1/30th sec. to 1/125th sec. Finally, the aperture is changed only as a last resort due to the physical noise generated by the camera's mechanical iris blades (heard as a series of clicking sounds).

目前一般BD影片,電影24P 格式同樣使用H.264作壓縮,流量30mbps以上,無論高亮或是暗部,都可以得到令人很滿意的畫質了。5D2同樣採用H ... |
