Capture One Pro 8.3.4 Approved
While we have tested and approved Capture One Pro 8.3.4, we have had some camera connectivity issues over USB with El Capitan, so we still do not recommend upgrading to El Capitan at this time.*If you have upgraded to El Capitan, you must be using Capture One Pro 8.3.4.

Today Phase One has released Capture One Pro 8.3.4. This is a service release providing OS support (OS X El Capitan), bug fixes, and camera support.

We have tested this update and here are our results:

  • It was stable over all and showed no real issues other than what is mentioned below.
  • There are still some Phase One camera incompatibilities with El Capitan, which Phase One knows about and will be addressing in subsequent firmware updates. Here are a couple of highlights:
    • Phase One firmware updater software is not yet compatible with OS X 10.11 and cannot be used to update DF and DF+ camera bodies via USB. The connection to the camera will freeze when the update begins. Instead we suggest performing updates from a computer running OS X 10.10.5 or older.
    • CCD based IQ1, IQ2 and Credo backs will only connect via Firewire or USB2. USB3 connections will not operate. This will be resolved in an upcoming firmware update for the back.
      • CMOS backs and IQ3 backs with the latest firmware are not affected by this issue.
  • The text field bug from 8.3.0 is still present in 8.3.3. Here are the details:
    • On both Mavericks & Yosemite, if you edit a text field and then make a camera setting change, the text field refocuses & highlights all content. This results in mistakenly erasing content (such as naming conventions, etc) while attempting to use keyboard shortcuts.The Workaround: After editing a text field, click on a thumbnail in the browser window.

Recommendations and limitations

All users

  • When you have disconnected a camera do not reconnect a camera until the Camera tool status changes to “No Camera Attached”.
  • DNG support is for raw DNG only is not optimized for specific cameras.

Other Camera Users

  • Connecting some Canon cameras to the computer after launching Capture One might result in tethered capture being unavailable. If you experience this, connect the camera to the computer prior to launching Capture One.
  • This functionality is not supported for Fujifilm RAW files: processing/exporting to DNG, auto mask, healing with Repair Layers and LCC.
  • This functionality is not supported for sRAW/mRAW files: LCC analysis and healing with Repair Layers.
  • Canon Live View: The image is not rotated according to camera orientation, as Canon does not report the orientation during Live View.

Digital Back users

  • Battery charging on IQ systems can cause issues with stability over Thunderbolt adapters or in low power devices such as Laptops. Switch charging off if you suffer repeated disconnections.
  • For tethered shooting with Phase One digital backs make sure that your system can either supply at least 10W power via Firewire (more than most laptops can supply) or make sure to activate the “Force Battery” setting on the back. Use the 4.5m Phase One Firewire cable.
  • For tethered shooting with Leaf and Mamiya DM digital backs make sure that your system can supply at least 12W power via Firewire (more than most laptops can supply). Use a Leaf or Mamiya Firewire cable.
  • Unless otherwise specified for your Phase One camera system, do not open the shutter on the camera prior to opening the Live View window. Doing so will generate errors on the digital back after closing the Live View window. The recommended procedure for using Live View is to first open the Live View window, then open the shutter on the camera, use Live View as desired, when done, close the shutter on the camera, and close the Live View window.
  • For Leaf Backs and Mamiya DM systems, the camera body must be selected in preferences before connecting the back.
  • For Leaf Backs and Mamiya DM systems, in the case of a communication error during firmware upload, please wait 10 minutes before disconnecting the FireWire cable.
  • Leaf Aptus II 8 only works with black and white Live View.
  • Focus controls for iXR and iXA cameras are only supported by IQ and Credo backs.
