That's solid advice. I know that @kye has been recording at 4k 100mbps 8bit and that's basically the same as 1080p 10bit, but with a little more detail, which makes a ton of sense. I would also like to put the 1080p 12mbps 10bit Proxy on the S5ii up against my 4k 100mbps 8bit on my GX800. I'm not so sure the 4k would come out 10x ahead, especially since I can barely tell the difference at normal distances with 6k (and don't get me wrong, the 6k looks amazing at 100%). Of course, nothing is "for free", but 1080p HEVC gives a little bit of that impression sometimes. -
...and is that a Nagra IV open-reel tape recorder the sound op is using? -
I did a similar 1080p to 4k comparison with 10-bit 50p HEVC files from my OM-1 very recently (as a check after I'd updated the FW to the latest 1.6 version). 1080p is nominally 40Mbps and 4k is 150Mbps. With the 1080p upscaled to 4k (using the FFMPEG zscale 'spline36' filter), at normal viewing distance on a 55" native 4k OLED TV I could tell them apart (as I know what to look for) but it's not easy. A normal viewer wouldn't notice. I've done the same comparisons in the past with files from my G9 with the same result. As a consequence of this, most often I record in 1080p 10-bit and save 75% of the storage space, unless there is a reason to want maximum resolution/quality e.g. it's an 'unrepeatable' major trip or event, to allow for re-framing or extraction of 4k stills. For the last one (which is handy for wildlife), I often record at 4k 24/25/30p 10-bit as that is sharper on the OM-1 than 4k 50/60p, but use 1/100 shutter speed to reduce motion blur while being reasonably usable as video footage as well.

Actually, what am I blathering about?! The only time I need the EIS is for tracking the couple, outdoors, once, maybe twice. Doh. Absolute none issue. I'll simply put it on a function button! I'd normally be tracking at '42mm' and it will be '58mm'. I'll just increase the distance between myself and the subject by a couple of feet et voila. Move on, nothing to see here 🤪 -

Yes, after seeing more photos, it looks like it. I'm guessing the lens is the Angenieux 9.5-57mm zoom lens.
