  • Fixed: incorrect Lens Format tag in EXIF.

• Name: Firmware update v64 for EF-E Smart Adapter^TM 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.

• Name: Firmware update v63 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster® ULTRA
• Release date: 02 Oct 2019
• Benefits and improvements: 
  • Improved exposure accuracy during continuous shooting.
  • Improved AF stability with Tamron 35-150/2.8-4 VC OSD A043
  • If a hardware fault is detected with the aperture diaphragm there will be a very bright red blink with the LED of Mark V, Speed Booster II, CINE Smart Adapter and CINE Speed Booster. If that happens, check the aperture diaphragm if it is stopping down as commanded using the 'Aperture (DoF) Preview' function. Bring the lens to the lens vendor for a check-up. If the LED is lit with normal brightness in red it is just an indication of operation in Advanced mode. The aperture diaphragm hardware fault indicator is very bright.
  • For diagnostics, the firmware version of the lens is now appended to the EXIF lens name.

• Name: Firmware update v62 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster® ULTRA
• Release date: 22 June 2019
• Benefits and improvements: 
  • Increased AF speed on a camera with PDAF support when adapter is in Advanced Mode. With some camera bodies, for example A7 Mark III, AF-C will now focus in-between frames when camera is set to continuous drive (MID, HI, HI++) and the aperture is f/11 or faster. (f/8 for A7II and A7RII) Some vintage lenses, such as the original Sigma 50mm f/1.4 DG EX HSM (not Art), does not focus accurately in Advanced mode, but they will continue to work in Green mode. PDAF works only within a small central area. Outside, CDAF is used. It is not possible to support all PDAF points because metadata about the optical formula of the lens would be required, which we don't have.
  • Improved exposure accuracy and AF accuracy in Advanced Mode.
  • For CINE Smart Adapter (MB-EF-E-BT6) only, add support for the MZ/PZ switch of Canon PZ-E1 Power Zoom Adapter (with EF-S 18-135/3.5-5.6 "Nano" USM).
  • Fixed compatibility issue with lens firmware version 2 of Tamron 10-24/3.5-4.5 VC HLD B023E.
  • Fixed AF issue with Sigma 50-500/4.5-6.3 DG APO OS HSM with 1.4x teleconverter when zoomed away from 50mm.
  • Fixed compatibility issue with certain lenses and NEX-5N and one of the following: CINE Smart Adapter, CINE Speed Booster, Speed Booster ULTRA II or Smart Adapter V.
  • Fixed IBIS issue during continuous shooting

• Name: Firmware update v61 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster® ULTRA
• Release date: 10 May 2019
• Benefits and improvements: 
  • Fixed focus issue when Drive Mode is M (medium) or H (high) and Focus Area is set to Tracking on Sony A9 (ILCE-9) after upgrading camera firmware to 5.0. (NOTE: no autofocus between frames in Advanced Mode. Use Green Mode for AF-C still photography.)
  • Fixed excessive hunting with one-shot AF if camera is turned on while mode dial is set to movie.
  • Fixed occasional maximum aperture detection problem with Tamron 10-24/3.5-4.5 VC HLD B023 lens.
  • Added CN-E Cinema EOS Prime Lens iris display.
  • EXIF improvements.

• Name: Firmware update v60 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster^TM ULTRA
• Release date: 22 Mar 2019
• Benefits and improvements: 
  • AF reliability improvement and hunting reduction.
  • Support for "AF Stop" button on some Canon super-telephoto IS lenses as a customizable button which can be assigned to any of the more than 50 functions available using the 'Focus Hold Button' menu item on A6300, A6500, any A7 series camera and A9.
  • For CINE Smart Adapter (MB_EF-E-BT6) only, enhanced support for the EF-S 18-135/3.5-5.6 IS 'Nano' USM + PZ-E1 Power Zoom Adapter combination with power zoom control using PlayMemories Smart Remote Control App or the zoom rocker switch on some Sony cameras. WARNING: EF-S 18-135/3.5-5.6 IS 'Nano' USM is incompatible with any Speed Booster, even after modification by removing the rear plastic shroud, because the rear element of the lens interferes with the front element of Speed Booster at 18mm (before boost). If PZ-E1 zooms the lens to 18mm by force, serious damage to the lens and/or the Speed Booster may occur. Restrict use of the EF-S 18-135/3.5-5.6 IS lens to the Smart Adapter without optics.
  • Added EXIF lens names for Sigma 17-50/2.8 EX DC OS HSM, Tokina AT-X 11-20/2.8, Zeiss Otus 55/1.4 and 85/1.4. (The EXIF lens name feature is not available for Mark I, Mark II, Mark III and the original Speed Booster, and is not supported by older Sony cameras.)
  • Fixed EXIF LensInfo field for Canon EF 70-200/4L IS II USM and Canon EF Extenders.
  • Fixed EXIF lens name when Canon EF Extender and Kenko Pro300 teleconverters are stacked and used with certain lenses.
  • To promote adoption of the latest firmware we offer assurance that the upgrade is reversible by including all previous versions released since 2017 (in the same download). Within Metabones App you may select which version to downgrade to. Should you require even older versions please email support@metabones.com.

• Name: Firmware update v59 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster® ULTRA

• Name: Firmware update v58 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster^TM ULTRA
• Release date: 12 Mar 2018
• Benefits and improvements: 
  • Continuous video AF performance improvement (works in Advanced mode only)
  • Addition of a custom function to Metabones App which lets the user to configure video AF speed/smoothness/noise level.
  • EXIF improvement.
  • Improved operation with Kenko Pro300 1.4x and 2x (blue dot) teleconverters.
  • Fixed a rare phenomenon where an old model camera with Mark V, Speed Booster ULTRA II, CINE Smart Adapter or CINE Speed Booster ULTRA with the IBIS switch at the OFF position may leave the LED indicator on in blue.
  • In Green mode, you may now attach an EF Extender first and turn on the camera before attaching a compatible EF telephoto lens. In advanced mode, you must not leave the EF Extender without lens while the EF Extender is attached.
  • If you have an early production CINE Smart Adapter or CINE Speed Booster, the manual lens EXIF definition custom function (preset using Metabones App) will no longer activate automatically. Press the WO/CF button on the adapter to activate.

• Name: Firmware update v57 for EF-E Smart Adapter^TM MARK IV/V and EF-E Speed Booster® ULTRA
• Release date: 26 Jun 2017
• Benefits and improvements: 
  • Added autofocus support during high speed and medium speed continuous drive (up to 10fps) on Sony A9 ("Green" mode only). Experiment with the "Priority Set in AF-C" setting for the best compromise between hit rate and frame rate for your shooting style. Overall performance depends on lens used. The camera does not use hunting while tracking is in operation. If subject movement exceeds the measurement range of the OSPDAF sensor, autofocus pauses. This is by design. The measurement range of the OSPDAF sensor decreases as the focal length increases. Except for the original Mark I Smart Adapter this feature is available for all subsequent Speed Boosters and Smart Adapters.
  • Enabled AF illuminator (Advanced mode only).
  • There is an AF accuracy issue when using AF-S or DMF on Sony A9 and telephoto lenses with Metabones in "Advanced" mode, which affects this and all previous firmware versions. Green mode, which is set by default on Sony A9, is not affected (except for the original Smart Adapter Mark I, which does not support "Green" mode). A9 users are advised to not use "Advanced" mode but stick with the default "Green" mode. In addition, some telephoto lenses rarely exhibit this issue, such as EF 200/2.8L II USM, EF 400/5.6L USM and Tamron 150-600/5-6.3 VC USD A011. Investigation of this issue is still in progress.
  • Fixed AF issue with EF-S 10-18mm f/4.5-5.6 IS STM and EF-S 18-135/3.5-5.6 IS Nano USM lenses.
  • Fixed smooth iris support for 40/2.8 STM, 50/1.8 STM and Sigma 50-100/1.8 DC HSM Art 016.
  • Fixed CN-E 18-80 T4.4 L IS KAS S servo zoom used by the camera's zoom rocker and the lens' rocker in alternation.
  • Fixed CN-E 18-80 T4.4 L IS KAS S auto iris when adapter is in Green mode, where extremely bright conditions no longer causes the iris to close completely.         
  • Fixed aperture display with Canon EF 300mm f/4L IS USM lens and Kenko Pro 300 teleconvertter.
  • Corrected W-T zoom scale display in "Advanced" mode for Speed Booster and Kenko Pro 300  teleconverter (except Mark I/II/III and original Speed Booster).
  • Faster aperture diaphragm for still photography in Advanced mode when Live Vide mode is set to Setting Effect OFF.
  • LED (if available) now shows solid magenta when adapter is connected to USB waiting for Metabones App to run.
