I have decided to extend this topic just a bit. I have not seen new test videos for them, but I have decided to post the manufacturers' summaries of changes for firmware updates of various cameras. These go beyond video, but many changes (such as lens support) affect video as well as stills. Moreover, as I have said before, sometimes when firmware is upgraded, things "break". These are called regressions. If you do not need an upgrade, sometimes it is best to not install one, because such unexpected problems might result.
Nikon Z6 version 3.30 2021-04-26
Changes from “C” Firmware Version 3.20 to 3.30
• A Save focus position option has been added to the SETUP MENU. If On is selected, the focus position in effect when the camera is turned off will be restored when the camera is next turned on. This option applies only when the camera is used with Z mount autofocus lenses.
• A Voice memo option has been added to the roles that can be assigned to the Movie record button via Custom Setting f2 (Custom control assignment). In the Voice memo role, the movie-record button can be used to record and play voice memos up to about 60 seconds long while a picture is displayed.
• Fixed an issue that would sometimes cause the camera to stop responding when time-lapse movie recording was interrupted.
Changes from “C” Firmware Version 3.12 to 3.20
• Support for RAW video output is available via a fee-for-service upgrade, * and firmware version 3.20 adds support under this service for Blackmagic Design external video recorders (currently the Video Assist 5″ 12G HDR and Video Assist 7″ 12G HDR). If you have already purchased the RAW video output upgrade for your camera, updating to firmware version 3.20 will add support for Blackmagic Design external video recorders automatically.
• Users of Apple’s Final Cut Pro X (version 10.4.9 or later) can now adjust ISO sensitivity—and display and adjust color temperature—for ProRes RAW footage output to ATOMOS NINJA V external recorders using the fee-for-service RAW video output upgrade. *< Choosing a RAW Output Type >
Before filming RAW video, choose an option for HDMI > Advanced > RAW output options > RAW output type in the SETUP MENU based on the type of recorder connected: select Type A for NINJA V recorders and Type B for Video Assist recorders.• Added support for NIKKOR Z 50mm f/1.2 S lenses.
• Fixed the following issues:
- Rotating the focus or (if Focus (M/A) is assigned to the control ring) control ring would sometimes fail to activate manual focus during burst photography when a NIKKOR Z lens was attached.
- The exposure indicator would not be displayed in mode M when a non-CPU lens was attached via an FTZ mount adapter.
- Certain aperture values would not be selected when control rings for the following lenses were rotated to stop aperture down in movie mode:
▹ NIKKOR Z 24-50mm f/4-6.3
▹ NIKKOR Z 24-200mm f/4-6.3 VR
▹ NIKKOR Z DX 16-50mm f/3.5-6.3 VR
▹ NIKKOR Z DX 50-250mm f/4.5-6.3 VR
• Unexpected aperture values would sometimes be displayed during bracketing in mode M if a bracketing option that made changes to aperture was selected with a NIKKOR Z lens attached.
• Power aperture controls would sometimes stop responding after the standby timer had been on for an extended period in movie mode.
* The RAW video output upgrade is available on a fee-for-service basis. For more information, contact a Nikon-authorized service representative.
Changes from “C” Firmware Version 3.11 to 3.12
• Fixed an issue with firmware versions 3.10 and 3.11 in which fine-tuning values selected for AF fine-tune > Saved value were not correctly applied when pictures were taken.
Changes from “C” Firmware Version 3.10 to 3.11
• Fixed an issue that occurred when the camera was used with an MB-N10 battery pack with two batteries installed and an EN-EL15 or EN-EL15a in Chamber A, namely that the camera would sometimes fail to switch to the battery in Chamber B when the battery in Chamber A was exhausted.
Changes from “C” Firmware Version 3.00 to 3.10
• Added support for Nikon Z mount TC-1.4x/TC-2.0x teleconverters.
• Added support for F mount lens firmware updates. F mount lens firmware updates are supported from FTZ mount adapter firmware version 1.10.
• Changed some of the f/-number values displayed when exposure is adjusted in steps of 1/3 EV (f/1.2 is now displayed as f/1.3). As of July 21, 2020, this applies to NIKKOR Z 58mm f/0.95 S Noct lenses.
• The bracketing increment is now properly applied to photos taken with exposure locked during AE bracketing in Continuous H (extended) release mode.
• When an external recorder compliant with Atomos Open protocol is connected, movie recording can now be started and stopped using camera controls if all the following conditions are met:
- The camera is in movie mode and the recorder is connected via HDMI.
- A memory card is inserted.
- The following are selected for HDMI > Advanced in the SETUP MENU:
▹ External recording control > On
▹ Output data depth > 10 bit
▹ N-log setting > Off
- 3840x2160; 30p/25p/24p is selected for Frame size/frame rate in the MOVIE SHOOTING MENU.
• Fixed the following issues:
- The camera monitor would exhibit a green cast when the camera was connected to an external display via HDMI if:
▹ Adobe RGB was selected for Color space in the PHOTO SHOOTING MENU,
▹ Shutter-release button > Record movies was selected for Custom Setting g2 (Custom control assignment) in Group “g” (Movie) of the CUSTOM SETTING MENU,
▹ 10 bit was selected for HDMI > Advanced > Output data depth in the SETUP MENU,
▹ On (cannot record to card) was selected for HDMI > Advanced > N-Log setting in the SETUP MENU,
▹ On was selected for HDMI > Advanced > View assist in the SETUP MENU, and
▹ movie mode was selected with the photo/movie selector.
- The crop selected for “tall” (portrait-orientation) pictures using PictBridge would not be accurately reflected in the printed image.
- In rare circumstances, autofocus would not engage if a NIKKOR Z DX 16–50mm f/3.5–6.3 VR lens was extended at the same time the camera was turned on.
Changes from “C” Firmware Version 2.20 to 3.00
• Added support for ProGrade and Lexar CFexpress memory cards (Type B) and confirmed operation with SanDisk CFexpress memory cards (Type B). For more information, see the Nikon website for your country or region.
• Custom Setting a4 (Auto-area AF face/eye detection) now offers an Animal detection option that adds dogs and cats to the subjects supported by face- and eye-detection autofocus. As a result, the camera can now detect and focus on the faces and eyes of dogs and cats. Animal face detection (but not eye detection) is also available in movie mode.
• Improved the functionality of subject-tracking AF (available when Auto-area AF is selected for AF-area mode) as follows:
- Subject-tracking AF can now be initiated via the Fn1 or Fn2 button on the camera or the Fn1 or Fn2 button on the lens. Subject-tracking AF must first be assigned to the control using Custom Setting f2 (Custom control assignment) in Group f (Controls) of the CUSTOM SETTING MENU or Custom Setting g2 (Custom control assignment).
- When AF-C (continuous-servo autofocus) is selected in photo mode, the operation of subject-tracking AF has changed as follows:
If subject-tracking AF is initiated by pressing the AF-ON button or by pressing the shutter-release button halfway, releasing the button ends tracking. Ending tracking by releasing the button restores the focus point in effect before tracking started. The intent of this change is to replicate the behavior of digital SLR cameras when 3D-tracking is selected.
• Custom Setting f2 (Custom control assignment) in Group f (Controls) of the CUSTOM SETTING MENU now offers a Lens Fn2 button option, which can be used to choose the role played by the L-Fn2 button available on certain Z mount lenses (as of February 12, 2020, only the NIKKOR Z 70–200mm f/2.8 VR S).
• Added support for the focus limit switch available on certain Z mount lenses (as of February 12, 2020, only the NIKKOR Z 70–200mm f/2.8 VR S).
• Optimized the responsiveness of the switch to manual focus when the focus or control ring on a Z mount lens is rotated during autofocus. Note that the control ring only functions in this capacity when assigned the Focus (M/A) role.
• Fixed the following issues:
- When Viewfinder brightness was adjusted manually, brightness would sometimes change when the standby timer was restarted.
- iOS devices running iOS 13 would sometimes display a Bluetooth pairing request when pairing was complete.
Note: For information on the license for the open-source software included in the camera’s NVM Express driver, see “BSD License (NVM Express Driver)”.
Changes from “C” Firmware Version 2.10 to 2.20
• Added support for Type B Sony CFexpress memory cards.
Note: For information on the license for the open-source software included in the camera’s NVM Express driver, see “BSD License (NVM Express Driver)”.
• Added support for distortion control with AF-S NIKKOR 120–300mm f/2.8E FL ED SR VR F-mount lenses.
• Fixed an issue that resulted in colored lines appearing at the bottom of the display when pictures shot in demo mode with FX (36x24) selected for image area were viewed at zoom ratios over 100%.
Changes from “C” Firmware Version 2.01 to 2.10
• Added supported for optical VR with NIKKOR Z DX 16–50mm f/3.5–6.3 VR and NIKKOR Z DX 50–250mm f/4.5–6.3 VR Z-mount lenses. Note that attaching these lenses disables the Mechanical shutter option for Custom Setting d5 (Shutter type) in Group d (Shooting/display) of the CUSTOM SETTING MENU, leaving a choice of Auto and Electronic front-curtain shutter options only.
• ISO sensitivity can now be adjusted using the lens control ring, and ISO sensitivity has been added to the options available for Custom Setting f2 (Custom control assignment) > Lens control ring in Group f (Controls) of the CUSTOM SETTING MENU.
• As of November 14, 2019, the aperture display in the lens info panel for NIKKOR Z 24–70mm f/2.8 S and NIKKOR Z 58mm f/0.95 S Noct lenses shows both the current aperture and adjacent aperture values in modes A and M.
• When On was selected for Auto ISO sensitivity control and an option that does not include “slow sync” was selected for Flash mode, shutter speed was formerly restricted to values between those chosen for Custom Settings e1 (Flash sync speed) and e2 (Flash shutter speed), but this has now been changed to match the behavior of digital SLR cameras, with the result that the minimum shutter speed now corresponds to the value selected for Auto ISO sensitivity control > Minimum shutter speed.
• Fixed an issue that in extremely rare cases resulted in the camera failing to correctly record movies with 1920x1080; 120p selected for Frame size/frame rate.
• Fixed an issue that occasionally resulted in “noise” in the form of white lines at the bottom of the display when the electronic viewfinder was on.
• Fixed an issue that in rare cases resulted in “noise” in the form of fine horizontal lines appearing throughout the frame in movies and the live view display.
• Fixed errors in the UTC time zones for the following three cities in the Time zone and date > Time zone display in the SETUP MENU:
Caracas: was -4:30, is now -4:00
Casablanca: was 00:00, is now +1:00
Ankara: was +2:00, is now +3:00
• Fixed an issue that resulted in an incorrect date of creation being displayed in the Windows 10 “properties” dialogs for movies and time-lapse movies created with the camera, as well as copies created with camera movie editing controls.
Changes from “C” Firmware Version 2.00 to 2.01
Fixed the following issues:
• If the camera detected faces during still photography or movie recording at the settings listed below, it would in very rare instances begin to respond more slowly, display an error, or stop responding altogether.
Still Photography
- Auto-area AF selected for AF-area mode in the PHOTO SHOOTING MENU
- Face and eye detection on or Face detection on selected for Custom Setting a4 (Auto-area AF face/eye detection) in the CUSTOM SETTING MENU
Movie Recording
- Auto-area AF selected for AF-area mode in the MOVIE SHOOTING MENU
- Face and eye detection on or Face detection on selected for Custom Setting a4 (Auto-area AF face/eye detection) in the CUSTOM SETTING MENU
• In very rare instances, the bottoms of pictures taken with all the following settings in effect would not appear as expected:
- Mode dial rotated to AUTO, P, or A
- An NEF (RAW) option selected for Image quality in the PHOTO SHOOTING MENU
- 14-bit selected for NEF (RAW) recording > NEF (RAW) bit depth in the PHOTO SHOOTING MENU
- Auto selected for Custom Setting d5 (Shutter type) in the CUSTOM SETTING MENU
- Continuous H (extended) release mode selected with the release mode/self-timer button
Changes from “C” Firmware Version 1.01 to 2.00
• Added eye-detection AF for use when taking photographs. To enable eye-detection AF, select:
- AF-S or AF-C for Focus mode in the PHOTO SHOOTING MENU
- Auto-area AF for AF-area mode in the PHOTO SHOOTING MENU
- Face and eye detection on for Custom Setting a4 (Auto-area AF face/eye detection) in the CUSTOM SETTING MENU
If the camera detects the face of a portrait subject, the face will be enclosed in an amber border indicating the focus point. If the subject’s eyes are detected, an amber border indicating the focus point will appear around either eye. If the camera detects more than one face or eye, triangles will appear to either side of the focus point; to position the focus point over a different face or eye, press the multi- or sub-selector left or right.
• Improved autofocus performance for photos and movies shot under low light: -3.5 – 19 EV (low light autofocus -6 – 19 EV), measured in photo mode with single-servo AF (AF-S) at ISO 100 and 20°C with an f/2 lens.
• The following improvements have been made to the Continuous H (extended) option for Release mode:
- Not only focus but now also exposure will respond to changes in the subject during shooting
- The burst shooting display after the memory buffer fills is now easier to read
• Reduced the length of time the display turns off (the blackout period) when pictures are taken with On or On (monitor only) selected for Image review in the PLAYBACK MENU.
• Item d5 in the CUSTOM SETTING MENU, formerly Electronic front-curtain shutter, has been renamed Shutter type and offers a choice of Auto, Mechanical shutter, and Electronic front-curtain shutter. If Auto is selected, the camera will automatically choose a shutter type according to shutter speed.
• Changed the color the focus point turns when the AF-ON button is pressed or the shutter-release button is pressed halfway with Auto-area AF selected and face detection or target tracking active.
• Edited and revised help text.
• Fixed the following issues:
- The camera would stop responding if certain operations were performed while HDMI output was in progress with 3840 x 2160 (4K UHD) selected for frame size.
- The value selected for maximum sensitivity would sometimes be exceeded during movie recording in mode M with On selected for Auto ISO control (mode M) if Active D-Lighting was enabled.
- The items in My Menu would sometimes not display correctly.
Changes from “C” Firmware Version 1.00 to 1.01
• When On is selected for HDMI > Advanced > N-Log setting in the SETUP MENU, Maximum sensitivity now takes effect during movie recording if:
- the camera is in mode P (programmed auto), S (shutter-priority auto), or A (aperture-priority auto), or
- the camera is in mode M (manual) and On is selected for ISO sensitivity settings > Auto ISO control (mode M) in the MOVIE SHOOTING MENU.
• Fixed an issue that resulted in third-party software showing an incorrect value for the Exif 35 mm format equivalent focal length field for photographs taken with a non-CPU lens connected via an FTZ mount adapter with the focal length specified using the Non-CPU lens data item in the SETUP MENU.
• Fixed an issue that resulted in photographs taken using optional flash units being overexposed if a face was detected in flash modes in which Auto-area AF would be selected for AF-area mode.
• Fixed an issue that resulted in an incorrect aperture being selected in mode P (programmed auto) with a flash mounted on the camera under conditions in which f/32 would normally be selected.
• Fixed an issue which prevented flash units controlled via radio Advanced Wireless Lighting syncing with shutter speeds of 1/100 s or faster with:
- On selected for Flicker reduction shooting in the PHOTO SHOOTING MENU and
- Enable selected for Custom Setting d5 (Electronic front-curtain shutter) in the CUSTOM SETTING MENU.
