  • Updated

Released on September 16, 2026, Capture One 16.8.6 adds Assisted Review during tethering, improves Live View, and extends 2nd Gen Wireless Tethering to the Canon EOS R3 and Canon EOS R6 Mark III. It also brings day-zero support for the Canon EOS R8 Mark II with wired tethering, wireless tethering, and Live View, plus file support for the Ricoh GR IV, Ricoh GR IV Monochrome, and Ricoh GR IV HDF.

Capture One mobile 4.1 ships alongside this release, bringing Assisted Review and the expanded 2nd Gen Wireless Tethering to mobile too. For details, see Changelog (mobile).

Sessions and Catalogs created in versions earlier than 16.8.0 must be upgraded to open in Capture One 16.8.6. See Upgrading a Session, Upgrading a Catalog, and Restoring from backup.

Assisted Review during tethering

Assisted Review can now be enabled to analyze images during tethering, making it much faster to sort away those with closed eyes, missed focus, or flash misfires. Images are tagged as they come in.

Assisted Review is still in beta. A short feedback form is accessible from the tool if you'd like to share how it's working for you.

For details, see Assisted Review.

 

2nd Gen Wireless Tethering for Canon EOS R3 and EOS R6 Mark III

2nd Gen Wireless Tethering now supports the Canon EOS R3 and Canon EOS R6 Mark III, extending the same wireless tethering performance already available for other Canon bodies to these two cameras.

A RAW file usually takes 10 to 25 seconds to arrive over wireless. With 2nd Gen Wireless Tethering, it can appear fully editable in one to two seconds, with the full-resolution file reconciling automatically in the background once it finishes transferring.

For details, see 2nd Gen Wireless Tethering for Canon.

 

Live View improvements

You can now hide the tools and tool tabs in the Live View window, freeing up more screen space for the image itself. Select the window and use the same shortcut you'd use to hide tools in the main window. Tool visibility is independent between the two. The Live View window's minimum size has also been reduced, so it can now go smaller when the tools are hidden.

The Focus Meter cursor tool in the Live View window now has its own tooltip, making it clearer what the tool does.

4K monitors

For optimal performance on 4K monitors, we recommend doubling the initial specifications due to the increased computational demands. Additionally, investing in a high-performance GPU with ample VRAM is highly recommended for these configurations to handle the intensive graphics processing.

Recommendations and limitations

Note: The information provided here is subject to change and unintentional errors may occur. For any queries or further clarification, please contact support at https://support.captureone.com/

General guidelines

  • Browsing folders containing unsupported image files may affect application performance.
  • Previews from earlier versions of Capture One may be updated, which can affect the application performance the first time images are viewed in this version.
  • Using a non-US laptop keyboard might require changing some of the standard keyboard shortcuts.
  • Editing images in external applications other than Adobe Photoshop might result in unexpected behavior.
  • Operating under virtualization software (e.g., Parallels, Hackintosh, etc.) may cause instability. These OS configurations are not recommended.
  • Some cameras provide multishot functionality by way of multiple exposures or pixel shifting. In most cases, this functionality will not be available in Capture One. However, a single RAW file from the "stack" may be viewable and editable in Capture One (as if it was a shot in single Capture mode).
  • Special or auxiliary modes (like pixel shift) are only supported if noted. If the information provided is incomplete or you need specific information pertaining to support in Capture One, kindly reach out to Capture One Support at captureone.com/support.

File support

  • HEIC/HEIF support: Capture One supports HEIC/HEIF 8-bit files to the extent that the operating system supports the files. If you are on a Windows computer, you might need to download the two extensions "HEVC Video Extensions" and "HEIF Image Extensions" from Microsoft to enable support in Capture One.
  • Capture One DNG colors: DNG files from camera models with native support in Capture One will per default have their native Capture One colors applied. DNG files from camera models that are not natively supported in Capture One will have generic DNG Standard colors applied. Adjustments and settings from other applications embedded in DNG files are not supported.
  • Other file support: Layered Tiff and PSD files can be supported for viewing purposes only. Reprocessing the image will result in a new flattened image.
  • File size limitations: The smallest supported file for viewing has a minimum side of 16 pixels. The smallest supported file for editing has a minimum side of 512 pixels. The largest supported file is 715 megapixels or 65,000 pixels on the longest edge.

Known issues

  • You can find a list of known bugs in a dedicated community forum topic titled Known Bugs. Note that this list may not be up to date on the day of a new Capture One version release.
