Visualizer of AF data from Sony cameras JPEG&ARW EXIFs

Visualizer of AF data from Sony cameras JPEG and ARW (RAW) EXIFs

This tool allows to visualize some statuses of PDAF sensors or CAF stored in EXIF metadata of JPEGs and RAW (ARW) from Sony cameras. Auto focus statuses are parsed from EXIF and presented as ExifTool interprets them. I.e. this tool show where are focus points.

Most recent standalone single file (extracts all libs and runtime to temp folder, no python installed required) Win x64 version download link (no exiftool.exe included)

Win64 executable download

With this tool you can see:

• For SLT cameras with 15-points PDAF (SLT-A33, SLT-A55, SLT-A35, SLT-A65, SLT-A57, SLT-A58):
  • AF hit status for each sensor at shutter release. AF hit displayed by colors from black to white. Black = out of focus. White = In Focus
  • If Face Detection was on, and Face(s) detected - they are highlighted with red frame
  • What AF points were used for final focus adjustments (have additional RED frame)
  • What AF point was reported as in Focus (Yellow circle)

• For SLT cameras with 19-points PDAF (SLT-A77, SLT-A99):

  • AF hit status for each sensor at shutter release. AF hit displayed by colors from black to white. Black = out of focus. White = In Focus
  • If Face Detection was on, and Face(s) detected - they are highlighted with red frame

• For CAF cameras (for example, DSC-RX100M4, DSC-RX10M3 and many other older Cybershots)

  • If Face Detection was on, and Face(s) detected - they are highlighted with red frame
  • What area was reported as in Focus (Yellow circle). Actually what camera thinks it focused at.

• For Hybrid AF cameras (like ILCE-5100, ILCE-6000, ILCE-6300, ILCE-6400, ILCE-6500, ILCE-7RM2,ILCA-99M2, ILCA-77M2, ILCE-9, ILCE-7RM3, ILCE-7M3, DSC-RX100M6, DSC-RX10M4, DSC-RX100M7 and ILCE-7RM4)

  • If Face Detection was on, and Face(s) detected - they are highlighted with red frame
  • What area was reported as in Focus (Yellow circle). Actually what camera thinks it focused at.
  • What Focal Plane (on-sensor) AF points were used
  • Eye detection marker (when Eye AF used, no DPAF points data stored in exif, only Eye and Face positions recorded)
  • [ILCA-77M2, ILCA-99M2] Also Dedicated PDAF sensors statuses display

Reads both JPEG/ARW

This tool consists of:

• afv.py - main script itself doing all drawing.
• exiftool (should be downloaded separately (link below) and named as exiftool.exe and placed in the same folder as afv.py

Note: For easy use downloaded compiled already package)

Prerequisities for launching source script:

• Python 3.7 (code rewritten from Python 2.7 as it will be discontinued)
• matplotlib module installed (http://matplotlib.org/ or pip install matplotlib)
• rawpy (pip install rawpy) to read and render Sony RAW - ARW files)
• pillow (pip install pillow or pip install pillow-simd) to load and show JPG
• Phil Harvey's EXIFTool binary (named exiftool.exe) to be placed in the same folder as afv.py script. Exiftool download (http://www.sno.phy.queensu.ca/~phil/exiftool/)

Warning! You will get no results or corrupted results if you JPEG photos (their EXIF) were modified or by image processing software. So please use JPEGs straight from the camera.

s_afv's Issues

OSX - High Sierra support

Would love to see this adapted to work on OSX, specifically High Sierra. I don't know enough python to fix this but I am able to at least get the UI to launch with Python 2.7. However, when I click Open and chose the file nothing else happens or displays.

Windows 10 - not working

On Windows 10 seems ta app not working, after selecting file to open I have white screen, no photo is displayed.

No AF information for Sony ILCE-6000

Hi,

The tool returns "Focal Plane AF points used = 0".

Exiftools seems to return no info.
Running exiftool from the cmdline gives:
