A7sIII now listed at BHphoto and in Germany at Fotokoch

I got some more tidbits (Thanks source!). This is what he had to say about the A7sIII:

• Gyroscope data will be available for post stabilization like the FX9.
• Digital IS like the zv1 will be available for the first time on a full frame Sony Camera. This does not use further crop. Only the slight crop previously mentioned for UHD. The 4k is still 1:1 pixel readout.
• There may be features left out at launch that will be available via software update. Similar to the FX9 version 2.0 update coming later this year. They will be mentioned on the presentation next week.
• Compared to an FX9, this does not down sample 6K to 4K, which would require a 24mp sensor.
• There is at least 1 notable hardware and 1 software feature that still isn’t revealed.
• Anyone who wants quality full frame 4K that “just works” without any limitations will be very pleased with this camera. Let’s just say this is not a toy, it’s a workhorse!

The marketing phrase they could use is: “4K that works!” unlike some other recent 4k/8K camera from the competition :)

Here is another image of the Sony A7sIII with the fully articulating screen. Below you can see a screen grab from the LCD screen showing the 4k 100p 4:2:2 10bit setting

Rumored Sony A7sIII specs:

• New 12MP sensor with fast readout and S-Cinetone colorscience
• records FHD 240fps, 4k120fps 10bit 4:2:2 and 4K120fps raw over HDMI
• ONLY Up to 4k60 will be 10bit 4:2:2 internal.
• Downsampled 1080p from 4K, making this the best 1080p hybrid ever made! No line skipping or pixel binning.
• No internal RAW.
• 600mbps bitrate
• Base ISO 160 for S-LOG3
• no Dual ISO
• Max ISO 409600 (video)
  
• 16bit RAW output
• Sony claims 15 stops dynamic range
• Movie Edit add-on compatibility for Image Stabilization in post
• world’s highest resolution new 9.44 million dot EVF (QXGA resolution)
• same Sony A7rIV AF system
• new kind of passive (noise free) cooling system
• no overheating, no recording time limits (They are claiming to not have overheating issues for at least 1hr even at the highest framerate.)
• UHSII card and CFexpress Type A card support (each of th two slots takes them both!)
• Looks pretty similar to a Sony A7rIV.
• fully articulating screen like the one used by the Sony ZV-1.
• The video record button is now on the top of the camera, placed behind the shutter button
• price around 4.000 Euro (A7sIII now listed at BHphoto and in Germany at Fotokoch)
• announcement late July
• shipment start mid August

This is the first leaked image of the new Sony A7sIII I got from J. (Thanks!). You can clearly see the red recording button, the LCD screen is fully articulating. Otherwise it’s pretty much close to the Sony A7rIV body.

I got another report from a source….Thanks :)

This is what he says:

The A7Siii will have the S-Cinetone colorscience.
The sensor will be an Exymos R CMOS Sensor.
Sony will add Movie Edit add-on compatibility for Image Stabilization in post. So far only RX0m2, RX100m7, and ZV-1 are compatible with that app. This is how they plan to match Cannon’s IBIS, it won’t be as good but at least it won’t be “warpy”. Also, the slight crop will be used to achieve this.
15+ Stops of dynamic range.
C4K in addition to UHD will be available.

Overall this camera is similar to the A7R4 tweaked in the same way as ZV-1 with similar specs to the FX9, but with a 12MP sensor. Like I said before there is a slight crop. Nothing seems extraordinary on paper except that EVF, but realistically there is no 4K60 10-bit internal 600Mbit camera on the market that can record unlimited video without overheating, with great autofocus and no fan.

I got info from five more people who sent me rumors for the first time. So I am not sure all is 100% correct so take the following info with a bit more caution than usual. I posted this info today and on July 28 we will see whom of them was right :)

Source 1:

• AF system is the almost the same as a7r4
• The video record button is now on the top of the camera, places behind the shutter button.
• 4K RAW output yes, but not sure if it supports 4K 120fps RAW output. Did not try but it says it’s 16bit RAW output.
• I did not have a chance to test out the RAW output because the firmware is not available, apparently Atomos is working on it to support a7sIII’s hdmi signal.
• dynamic range is 15 tested by Sony, so i guess it’s ard 13-14 in real life.

Source 2:

• Dials: Looking from the back panel of the camera, video dial for video mode selection left to EVF, photo dial for photo mode selection right to EVF. Exposure dial unchanged.
• Screen: Touch function available when navigating the menu.
• Ports: Removable port door. Two usb-c, one micro hdmi, no flash sync port.

Source 3:

• Here is something unfortunate, there will be a crop on the 4K. A small one, similar to a7s2.
• Also, ONLY Up to 4k60 will be 10bit 4:2:2 internal.

Source 4:

• They are claiming to not have overheating issues for at least 1hr even at the highest framerate.

Source 5:

• I can confirm 4k60 10 bit unlimited recording time.
• I can confirm at least 180fps 1080p with full AF and sound.
• Downsampled 1080p from 4K, making this the best 1080p hybrid ever made! No line skipping or pixel binning.
• No internal RAW.
• New codec similar to FX9.
• No 6K.

I can clarify definitively some points I wasn’t entirely sure about until today:

Sensor:

Sony A7sIII uses a new 12MP BSI sensor. There is no indication it uses the 48MP Quad sensor (downscaled to 12MP).

Cooling:

Sony A7sIII has no active vent. It only uses a pure new passive cool system.

Cards:

The camera has two slots. And each slot is capable of taking SD cards and the brand new CFexpress Type A cards.

Sony didn’t tell testers the exact price. In the USA they told them the price would be in the $3,500 range. But today a retailer told me the price in Europe would be around 4.000€.

If you know the exact price please drop me a message using the anonymous contact form. Thanks!
