Its cool for sure, but you have to remember you are choosing from very good JPEGs, not RAW. Its a great feature, but it does have its limitations.
Ah, an excellent point I had glossed over. Considering I only develop RAW files these days (I find it's critical to getting the most out of legacy lenses), a very valid one from my POV, too.
One bit of a counterpoint here; I think applying edits to JPEGs is severely underrated. A difference of working with stills and video is that if you're already shooting video, chances are you'll have your exposure and whatnot set correctly in the first place; if you have a good enough starting point, you don't generally need all the latitude raw provides. These days I end up editing JPEGs as much as RAW files simply for the workflow speed and efficiency, particularly now that Adobe supports Olympus colors so that the files still look relatively consistent.
Really made me laugh:
"Bad points
4k footage looks noisy at 800 ISO and above."
Edit: I just noticed he tested C-AF with the Oly 45 and the PL25, which doesn't have the faster focusing (is it 240hz sampling thats faster?), Really dropped the ball on that one. And he says the frame rate slows to 5 or 6 which makes me wonder what cards he was using. I haven't read that anywhere else.
I actually note in my own first impressions thread (in one of the later pages) that both of those lenses slow down the camera's C-AF burst rate (S-AF burst is of course unaffected), and by my own guestimation is closer to about 4fp. Accuracy remains top-notch though, something which I didn't at all expect from my Olympus lenses. I may need to double check, but this slow down happens even with shutter release priority turned on, which only affects capturing the very first frame.
Furthermore, the Olympus 12-50mm bursts at 6-7 fps with great accuracy(though less than that of the 35-100), despite supposedly not being supported by DFD.
As posted above, completely idiotic decision to test the continuous AF with an Olympus lens only. Which disables the new DFD feature!!

What a berk!
Bit of a correction here: he
did try it with the Panasonic 25mm F1.4 too... And yes, that lens slows the camera's C-AF burst. If I hadn't specifically remembered the 35-100's 240hz focus polling and requested one of those for my review, then I wouldn't have gotten the results I was hoping for in my own tests. Nowhere that I have seen does Panasonic specify that some of their lenses woulnd't be compatible with the quickest burst rate; I assumed that might be the case for the 20mm f1.7, for example, but definitely not the 25, so I can't blame Gordon for thinking performance wasn't what Panasonic quoted. It's one of Panasonic's most well known lenses, so it came as a surprise. I hope a firmware update can help speed up the 25mm f1.4 (240hz on the 35-100 was added in an early FW update), but I also don't really care about that for my personal use; accuracy is good, and I don't need more than 4fps for anything I can think of where I'd be using C-AF with the 25mm F1.4.
FWIW, I'm using a UHS Class I card, but that should have nothing to do with the 25 slowing down.
One other note is that the X-T1
does slow down its burst occasionally to get shots in focus, though not to the extent the Panasonic will do with slower lenses.
