Two More Cameras from Sony: Both Feature Internal 4K, 960fps Slow-Mo, & S-Log

Sony RX10 II
Yesterday, Sony's fully-featured a7R II stole the show, but that was far from the electronics company's only significant camera announcement.

Sony also announced the RX10 II and the RX100 IV. Both cameras feature the same stacked 1-inch CMOS sensor, and both have a fixed lens from Zeiss, albeit two different ones. Both cameras are capable of shooting 4K video internally to XAVC-S, and with S-Log2. The most eye-catching feature of these cameras, however, is their slow-motion abilities, as both are capable of bursts of 960fps (when shooting 24p) and a whopping 1000fps (with 25p).

So with the basics out of the way, here's some early footage from the RX10 II:

And here are the specs and photos of the RX10 II:

Sony RX10 II Front
Sony RX10 II Back
  • 20.2 MP 1″ Exmor RS BSI CMOS Sensor
  • BIONZ X Image Processor
  • Internal UHD 4K Video & S-Log2 Gamma
  • Carl Zeiss 24-200mm f/2.8 Lens (35mm Eq)
  • Slow Motion Video at 960 fps
  • 3.0″ 1228K-Dot Tilting Xtra Fine TFT LCD
  • XGA OLED Electronic Viewfinder
  • Built-In Wireless and NFC Connectivity
  • Low-Light Sensitivity to ISO 12800
  • Super Sonicwave Motor for Fast Autofocus
  • Price: $1300

And here are a few choice examples of what both of these cameras can accomplish in terms of slow motion:

And here are the specs and photos of the RX100 IV:

Sony RX100 IV Front
Sony RX100 IV Back
  • 20.1 MP 1″ Exmor RS BSI CMOS Sensor
  • BIONZ X Image Processor
  • Internal UHD 4K Video & S-Log2 Gamma
  • Zeiss Vario-Sonnar T* f/1.8-2.8 Lens
  • 24-70mm (35mm Equivalent)
  • 2349k-Dot OLED Tru-Finder Pop-Up EVF
  • 3.0″ 1229k-Dot Multi-Angle Xtra Fine LCD
  • Slow Motion Video at 960 fps
  • Built-In Wi-Fi Connectivity with NFC
  • ISO 12800 and 16 fps Continuous Shooting
  • Price: $950

As for the resolutions that you can pull from these cameras in their slow-motion bursts, here's a breakdown:

  • 4K/UHD 3840 x 2160 – 24/25/30p (XAVC-S 100Mb/s)
  • 1920 x 1080p: 60 fps, 30 fps, 24 fps
  • 1280 x 720p: 30 fps
  • 1920 x 1080p: 960 fps, 480 fps, 240 fps
  • 1824 x 1026p: 240 fps
  • 1676 x 566p: 480 fps, 240 fps
  • 1136 x 384p: 960 fps, 480 fps
  • 800 x 270p: 960 fps

While fixed lenses are traditionally a deal-breaker in this day and age, I can see these little guys carving out a solid niche as B and C cams to their big brothers in Sony's mirrorless line. With internal 4K, S-Log, and high frame rates, these could also fill that role, or serve as crash cams, for productions primarily using Sony's F5, F55, and F65. 

Like the a7R II, both the RX10 II and RX100 IV are going to be available for pre-order on June 17th, and both are expected to begin shipping late July. You can check out the RX10 II on B&H here, and the RX100 IV right here

I'm actually more interested in the RX100 IV than any of their recent announcements. I love the idea of having 4K and slow mo with me at all times in my shirt pocket. Never have to worry about missing a shot again.

Keep in mind that the RX100 Mk4 can only record 4K in 5 minute chunks, to prevent the camera from overheating.

The RX10 Mk2 records 4K in 30 minute chunks.

What just happened?! I remember getting excited about 1080p at 120fps, now 1080p at 960fps?! The real question is how long of a burst can it shoot at 960fps?

It won't be at full HD. Most likely upscaled. I do remember seeing it somewhere yesterday.

The cameras upscale the slow-mo so it's not true 1080p. The cameras shoot the slow-mo with a crop factor. Supposed to be:
1824 x 1026p: 120 fps
1676 x 566p: 240 fps
1136 x 384p: 480 fps
800 x 270p: 960 fps

i would like to see the quality of 1080P at 240fps since the 480 and 960 were not really usable for a film project (although very usable for scientific reasons which i may get this camera simply for machine analysis at work).

I would love to get the RX100 as my pocketable camera on vacation

120 is closest to true 1080p. 240 isn't too far off and should still be pretty usable imo.

I recently got to see my friend's FS7 in action at 180FPS and the quality was gorgeous.

A lot of the footage in the promo looks very broadcast video-y. I wonder if the camera's doing a lot of internal sharpening.

Also, surprising to see some poor highlight rolloff, even with s-log2.

I'd be interested to see a great DP get his or her hands on this camera, see if they can drag a film look out of the sensor.

It's hard to judge because almost all of Sony's promotional videos have very video look to them.

These promos were certainly not shot in log gamma. Sony promos are always strictly rec709 video that will look sharp and colorful on a Sony demo tv somewhere.

And it's more like what the average consumer will get straight out of the camera.

I would like to see more sensors with unified memory architecture like the RX10 II. It will boots the sensor readout speed 3x to 5x times faster.

Because let's face it, 960fps is to much fun: https://www.youtube.com/watch?v=hDI-hE_5GQw

Comparing specs, it looks like the RX10 ii outperforms the Canon XC10 in almost all specs. However, the XC10 write 305 Mbps for 4K while Sony writes 100 Mbps. I can't imagine Sony's compression is that much better, so Canon might have better color?

Isn't the Canon 4:2:2 colorspace? The new Sony cameras are all 4:2:0 :(

It all depends on how well the CODEC is implemented. A 100 Mbit variable bit-rate with effective encoding can equal 300 Mbit All-I CODEC.

So far the Panasonic and Sony 4K 100 Mbit encoders do a pretty good job of retaining detail with a low amount of artifacting.

Really impressed with what Sony have been doing for a while now. Now if they would just add DCI 4K to their gear as well I'd be extremely happy.

I can see these as primary cameras for those of us working alone. I want to find out if they are constant aperture?

The Rx10 has it at f2.8. But then again it is 8-bit, 4:2:0 colorspace. I think you will get a better picture out of a Blackmagic Pocket Camera in 1080p and then just upscale it to 4k, still will look better IMHO (In my honest opinion). Lofar!

I seriously doubt that anybody's 1080 HD image blown up is going to match either the Panasonic or Sony 4K image. In the tests I've seen the 1080 HD footage looks very soft and is missing tons of detail compared to the 4K footage.

And 4:2:0 color space is NOT as bad as you are making it out to be. Again I've seen lots of comparisons where people could NOT pick out the 4:2:2 footage from the 4:2:0 footage when properly shot and processed.

You doubt as much as you want. But that is the truth. Blown up BMPCC 1080p footage will look better. It's all about the dynamic range and the highlight rolloff and all that cinematic look. It does not have to be super sharp, on the contrary, when it's super sharp it will not look "filmic". It will not miss "tons of detail". Trust me. Have you even seen upscaled 1080p footage? And yes 4:2:0 is bad, it's not even broadcast standard and you get that "videoish" feel with it, just look att all the stuff shot with the GH4 vs. BMCC. I hope I haven't hurt your feelings as you are a good guy, but I think you are wrong on this one Guy.

I have seen upscaled 1080 HD footage and it looked soft and low detailed compared to real 4K footage.

And again I've seen tests comparing 4:2:0 footage with 4:2:2 and when shot correctly nobody could pick out the 4:2:2 from the 4:2:0 footage.

I really think Canon has produced a lame duck camera with the CX10, and it's going to be ignored by most of the film making community because it represents very poor value for the price you are paying.

yes the lens is f2.8 from 8-73mm. It's a software corrected, all servo operation: switchable zoom/focus ring, all operated by motors, not mechanical. This takes some getting used to. The original RX10 had a flaw where the zoom was only a single speed when recording: SUPER SLOW. It took almost a full 60 seconds to zoom the length of the lens. Hopefully this has been fixed and you can adjust the zoom at a decent speed while recording. Still love the original one but its flaws kept it from being first rate.

Hopefully this means an updated PXW-X70 is in the future!

Honestly this chip, software, and lens in an PMW-EX1 style body with 4k xavc 10bit 4:2:2 would work hard for a long, long time...and that's why it won't ever happen!

I hope there will be a servo handgrip accessory for it like the one for the FS7. I've been trying to determine if the Movcam accessory cable for the A7s that enables servo zoom with the Sony PZ lenses like the FE 28-135mm f4 would be compatible. Time will tell.

Nope. It records at "almost" 1080 HD resolution at up to 240 fps. The 960 fps is for a much smaller image size. ( still 240 fps is damn good for near 1080 HD resolution )

Am I the only one to think that the speed at which new cameras are being marketed can only hurt our community?

This is good for the consumer, but (truthfully) fuck the consumer.

Do we really need a new 4K camera from Sony every 3 months? This is getting ridiculously silly. Too much competition in technology, not enough in art.
