New Footage from 4K Cameras With Fixed Lenses – Canon XC10, Sony RX100 IV, and Sony RX10 II

Ok, so there are a few new 4K compact zoom options out there for those of you on the hunt for a 4K B-cam to your Sony A7s/FS7 or just a 4K vacation snapper. Canon was the first to let the world know it was getting serious about 4K by announcing a fixed lens compact camera called the XC10, which for some reason uses CFast 2.0 media cards for recording 4K (not 1080p – that’s on the SD card slot there, go figure…) due to the unnecessary high bit rate of 305Mb/s.

Later on, actually just a month ago, Sony kicked it up a notch (again) with the RX10 II ($1,300) and the Sony RX100 IV ($948 at B&H) including not just internal 4K at the much more manageable 100Mb/s in XAVC-S (on cheap as chips SDXC cards), but also super-slow mo and Slog-2. The Canon XC10 does feature Canon Log and Wide DR gamut, true and does produce nice images when graded, but it costs $2,500 and uses a significantly more expensive media.


Matter of fact CFast 2.0 right now is probably the most expensive non-proprietary media a camera can use – a 128GB Lexar 3400x Cfast 2.0 sells for about $370, and that’s one of the most affordable Cfast 2.0 cards out there! But I guess, the force was strong with Canon big wigs, who demanded that Cfast 2.0 and 305Mb/s 8bit 422 XF-AVC be implemented on the XC10 as it is meant to be used as a B-Cam to the upcoming C300 Mark II.

Sure, there is some logic in that, but for a very small fraction of the market. Some Canon C300 Mark II users may get the odd XC10 here and there for a B/C-cam, but Joe Schmoe will have some hard times explaining to his wife a $370+ charge on his credit card for a media card for his new camera (after shredding the page with the $2500 charge for the XC10)…

But I am getting carried away. I want to XC10 to wow me, I really want it to grow on me, but it is facing some serious competition from Sony. And while I am contemplating still whether to get an RX10 II or RX100 IV, after I sold my RX100 III, I went hunting in the dark corners of the Web and for some footage that might help me in my quest.


Here’s some footage from the Canon XC10 (BTS from a C300 II Shoot) it’s in Japanese, I think, and I have no idea what they’re saying but the actual video is shot on the XC10. (via Canon Japan)

This is a short recap video from a small festival called Gagnef Open that takes place in Dalarna each summer. I took the opportunity to try out my new camera, the Sony RX10 II. This video is shot in 4K, HD, HFR 240fps and 1080 100fps mode, S-log2 (PP7) Edited on a 1080p timeline in Premiere CC2015.

Rellay impressed with the camera and the picture it delivers, a super fun toy for run n gunning!

Never had a camera that shoots video in LOG before. Quite a challenge to grade the footage. Although, quite pleased at this first attempt. Need to reduce the grain in the shadows. Hopefully, will get the hang of it.

This last one might be an RX10 II or RX100 IV not sure, but a big thanks to Emanuel over at for sharing some of these.

Sony RX100 IV – $948 at B&H

  • 20.1 MP 1″ Exmor RS BSI CMOS Sensor
  • BIONZ X Image Processor
  • Internal UHD 4K Video & S-Log2 Gamma

  • ISO 12800 and 16 fps Continuous Shooting

Well, that’s some seriously impressive footage from the Sony RX10 II above, and the much smaller RX100 IV isn’t too far off, but of course I can’t base my decision and neither should anyone based on just a few videos. If you can, it’s always better to try one at a shop wherever possible.

Here’s what I gather are the differences/similarities between the 3 models apart from the price.

  • All share a 1-inch size sensor (XC10 – 8.29 MP / the Sony’s at 20 MP)
  • the RX10 II and RX100 IV use Stacked BSI sensors for optimised low-light performance
  • RX10/100 IV ISO max is 12,800
  • Canon XC10 max ISO is 20,000
  • Canon XC10 cannot record HD on the Cfast 2.0 card; only on SD and visa versa.
  • XC10 – 1080/60p and 720/120p
  • Lens on the XC10 is f5.6 on the long end
  • Sony RX10 II – is f2.8 fixed / RX100 IV is faster f1.8-2.8
  • RX100 IV 35mm FOV equivalent is about 24-70
  • RX10 II lens is 24-200mm and XC10 is about 24-240mm
  • In UHD Canon XC10’s widest FOV is 27.3mm due to crop.
  • XC10 uses significantly more expensive media for 4K recording
  • Sony RX10/100  – XAVC-S 100Mb/s vs. Canon XC10 XF-AVC at 305Mb/s (3x that of the Sony codec)
  • The built-in image stabilisation in the XC10 works only in FullHD, not 4K!
  • RX10/100 IV – super slow-mo 960fps/480/240 burst, non-continuous
  • RX100 IV limited to 5 minutes 4K clips
  • Both Sony have Slog2 ; Canon XC10 Canon LOG
  • 1080p/120 is continuous on both Sony models
  • No headphone or mic input on the RX100 IV
  • the RX10 II has both 3.5mm mic input and headphone jack

There’s a lot more, but that’s all the time I have for now. I am curious to see what you guys think of these cameras? Are any of them fitting in your workflow?
