Metabones Firmware Update V0.64 Now Available

Metabones firmware update V0.60 for Metabones Smart Adapter IV/V and EF-E Speed Booster ULTRA 0.71x are now available.


  • Name: Firmware update V0.64 for EF-E Smart AdapterTM MARK IV/V and EF-E Speed Booster® ULTRA
  • Release date: 01 Sept 2020
  • Benefits and improvements:
    • Fixed compatibility issue when Tamron 150-600/5-6.3 VC USD A011 is used in conjunction with a Kenko Pro300 teleconverter.
    • Sigma 50-100/1.8 DC HSM Art 016, Sigma 135/1.8 DG HSM Art 017 and Tamron 15-30/2.8 VC USD A012 now fixed to perform initial calibration only once. The camera needs to be switched off and in the case of the zoom lens (50-100/1.8) the zoom needs to be rotated back and forth between the wide and the tele end once to store lens calibration data.
    • Fixed incorrect auto-cropping for Tamron AF ASPH XR Di LD (IF) 28-300/3.5-6.3 MACRO A06.
    • For diagnostics the firmware version of the lens, if available, is now appended to the EXIF lens name.
