UKAirscape | Low light: Sony AXP33 (AX33) vs Panasonic VX870 gain tests HD mode @UKAirscape | Uploaded 9 years ago | Updated 1 hour ago
Testing how the Sony FDR-AXP33 (AX33) and Panasonic HC-VX870 (WX970) compare when the light's dim and you need to start adding in gain - THIS TEST IN HD MODE. See my other video, link below, for the equivalent 4K test.
And yes - there are differences between the 4K and HD tests! You'll have to watch to find out what they are :-)
NOTE: the Sony has weirdly limited manual exposure controls which means I can't absolutely guarantee that this test is precisely like-for-like. Sorry, it's the way Sony have implemented their Auto / Manual function.
Specifically, I fixed shutter at 1/50 to match the Panasonic, then could only use the Auto Gain Limit control to gently allow the camcorder to bring the gain up from 0. This was done on the basis that it was so dark that the lens would already have to be at maximum aperture but sadly the Sony doesn't actually confirm the aperture to you when it's on Auto (which it has to be if you set the shutter speed to manual! Yes, it's peculiar. You can only have *either* Shutter or Iris or "Exposure" (the don't define this anywhere) on manual, at which point the others change to Auto)
******* If anyone watching has a better way of ensuring the two are matched and controlled equally, I'd be delighted to hear it *************
