Nikon Z6 III sensor readout speed measurements

My name is Adam and go by “horshack” on dpreview. This year I started a crowd-source project on GitHub for measuring the sensor readout speeds for as many cameras as possible. The methodology involves custom firmware running on an inexpensive Arduino board that flashes its built-in LED at a known frequency, which is then photographed and videoed in each of the camera’s photo and video modes to calculate the readout speed from the number of bands that appear in the captured image. The GitHub repository includes a deep dive into how rolling shutters work, plus instructions and source code you can use to perform your own measurements.

The project’s home page is at:

https://github.com/horshack-dpreview/RollingShutter

The live results page for the project is at:

https://horshack-dpreview.github.io/RollingShutter/

For example, here are the different camera sensor readout speeds combined results (full-sensor, milliseconds):

Nikon 2

Nikon 2 (by RC Jenkins)

Occasionally, I bring up a hypothetical system I’d like to see from Nikon.

It won’t happen; but this is more of a thought experiment for a discussion to get the creative juices flowing for people who think creatively and to get the defensive juices flowing for people who don’t.  So get ready to pick your side and dig in. Because honestly, who really needs to hear anything at all from anyone else before just arbitrarily picking the side you already wanted to be on anyway?  Here we go (again)…

The system is called Nikon 2; and Nikon 2 is the spiritual successor to Nikon 1.  If you’re really good at counting, you’ll note that it’s also the numerical successor to Nikon 1. hmmm…what did that “1” stand for again…?  Wasn’t it the number of units they sold?  Or something like that.

Nikon 2:

  • shares the Z mount and is fully compatible with all Z lenses
  • does not have a huge selection of dedicated lenses
  • Uses the latest, greatest sensor technologies
  • Introduces novel features that would be risky or expensive for higher-end cameras
  • Is affordable for more people
  • Is designed primarily for producing online content
  • In practice, exceeds in IQ well beyond APS-C cameras and phones
  • Has a sensor that is…nope…it’s still too soon.  We need more context.

So here is one example of a Nikon 2 camera’s specifications:

  • 14-bit sensor readout: 1/240+
  • No mechanical shutter
  • HDR option on-sensor
    (can quickly take 2 shots at different exposures, like an iPhone)
  • IBIS that can move faster & further, resulting in gimbal-like stabilization
  • 4K120 12-bit raw video.  10-bit ProRes HQ 422, h.265.  HD240.
  • Direct USB-C connection to record or monitor video on a phone via app
  • 30FPS raw stills
  • Latest Expeed 7 AF
  • Priced between $500 – $1000
  • Rapid pixel-shift for 8K stills
    (Rapid, to reduce motion blur)
  • Novel features, perhaps the ability to internally rotate the sensor for portrait vs landscape
  • 4K native resolution (3820 x 2160 = 8MP); perhaps also a 6K option
  • Sensor size:  21.3 x 12 mm (16:9 native; or could be vertical-native)
    (^ There it is)

Why is it so cheap? Not only does it lack a mechanical shutter; but the sensors are far cheaper than either full-frame or APS-C. In just one simple example, suppose they use a 12″ wafer for sensors. They might be able to make 64 full frame sensors from this; but they might be able to make 240 Nikon 2 sensors from the same sized wafer. When accounting for defective sensors, each Nikon 2 sensor might be 4x (or more) cheaper, depending on the technology.  For example, stacked sensors might have a higher / compounded defect rate.  Here it is visualized:

Nikon has several new design patents, but they are all “secret” and cannot be accessed


After years of finding interesting information on upcoming cameras and lenses in the latest design patents, Nikon finally found a solution by filing “secret” patents. This probably explains why we have seen only a few Nikon patents in the past few years. Currently, there are four new Nikon design patents that are marked as “secret” and cannot be accessed (in fact, the last ten patents filed by Nikon are also ” secret”):

The new Nikon Imaging Cloud service


 
Together with the Z6 III camera, Nikon also introduced a new cloud service called Nikon Imaging Cloud, similar to the old Nikon Image Space:


The Nikon Imaging Cloud can be used in a web browser or smart device, and it will provide the following services:

  • Image transfer: Upload images shot with the camera to Nikon Imaging Cloud and send them to external online storage.
  • Imaging recipe: Save image shooting data as a recipe. Create your own recipes or select from “public recipes.”
  • Providing Picture Controls: Download Picture Controls from Nikon Imaging Cloud and import them to the camera.
  • Firmware update: Download firmware directly to the camera from Nikon Imaging Cloud.

The new site (not yet active) is located at https://ment.imagingcloud.nikon.com/.

Nikon Self Service Repair program expanded for more cameras, lenses, and accessories


When Nikon started their Self Service Repair program, it had only one lens and one rangefinder. Later, the Nikon Z6 III camera was added.

Nikon has now expanded their Self Service Repair program to include several cameras, lenses, and accessories:

Firmware update version 1.70 released for the Nikon Zfc camera


Nikon released a new firmware update version 1.70 for the Zfc camera with a single fix:

  • Fixed an issue that occurred in rare cases where tapping the monitor would not move the focus point to the selected position.

The Nikon Zfc pricing starts from $956: Adorama | B&H.
