CaptainFrom inside a room with no lights on, looking towards a large window with mid-morning cloudy daylight, I ran 10 seconds of HDR, then switched to normal video, and ran another 10 seconds with a 1.7x zoom, carefully ensuring the framing was the same as before.The 1.7x zoom indeed is the amount required to replicate the HDR crop - am I right in thinking that 1.7x zoom has been said to be more or less lossless (so maybe that's why the HDR has that crop)?Anyway, the differences between the two clips - in terms of blown highlights and areas going to black - was more or less none.As the shots reveal my untidy house, I won't post them, sorry.
So, I can't imagine using this feature, but then again, I was never much interested in it anyway, but I realise this will be a big disappointment for some.
