Last test on this before vacation.
The problem with manual mode during evening/morning hours is that the light drops resp. kicks in so drastically. After some further reading on the topic, the best way to avoid such is to switch to Aperture-priority mode during capture. However, this will introduce flickering which can be very annoying.
After doing some tests with deflicker-software, I am pretty much satisfied with the output of TDLF.
Of course, the direct light in the sun will still cause issues, but not as much. For the video I used the D2x with the Sigma 30f/1.4 all mounted on the AllView head.
