Green and Advanced Modes
A Tale of Two Modes
Your Metabones EF-E Speed Booster ULTRA / EF-E Speed Booster / EF-E Smart Adapter II / EF-E Smart Adapter III/ EF-E Smart Adapter IV has two different operation modes. Each mode supports a different set of features. You select the operation mode when you mount the lens. The following table summarizes the differences between the two operation modes if your camera is A6300, A6500, A7 Mark II or A7R Mark II.
|Green Mode||Advanced Mode|
|Fast phase-detect autofocus in photo mode||Fast contrast-detect autofocus, albeit not as fast and/or accurate as "Green" mode phase-detect AF|
|Excellent compatibility with virtually all AF lenses||Autofocus works with most lenses but compatibility is not as broad as in "Green" mode|
|No Eye-AF function||Eye-AF|
|AF-C with good performance, albeit photo mode only but not during video recording||AF-C may have unsatisfactory performance and/or accuracy and may suffer from excessive hunting, depending on lens - use AF-S or DMF|
|Full PDAF area of the sensor may be used, even though edge and corner PDAF points may have difficulty locking with some lenses||PDAF area limited to the center portion of the frame, but edge and corner AF points may actually work more reliably because contrast-detect AF works over the entire frame|
|May have difficulty locking with long telephoto lenses under less-than-ideal shooting conditions (good lighting, high contrast and small focus movements required)||More even performance across different shooting conditions when using long telephoto lenses, but not as fast under ideal conditions|
There is no "right" setting, but based on customer feedback most A6300/A6500/A7 Mark II/A7R Mark II users prefer "Green" mode. Use "Advanced" mode if you find lower AF speed and using AF-S acceptable and you want the extra AF features or more robustness with long telephotos and edge/corner AF points.
For cameras other than A6300, A6500, A7 Mark II and A7R Mark II,
|Green Mode||Advanced Mode|
|Slow contrast-detect autofocus||Fast contrast-detect autofocus|
|No AF-C support||AF-C may have unsatisfactory performance and/or accuracy and may suffer from excessive hunting, depending on lens - use AF-S or DMF|
|No auto-iris function on FS and VG camcorders||Auto-iris on FS and VG camcorders|
|No wide-open button function||Use wide-open button of the adapter to set the lens to wide-open momentarily for ease of manual focusing|
We recommend users of cameras other than A6300, A6500, A7 Mark II and A7R Mark II to use the "Advanced" mode.
These are the additional differences on all camera bodies.
|Green Mode||Advanced Mode|
|LED on adapter is blue (on CINE, Mark V and Speed Booster ULTRA II)||LED on adapter is red (on CINE, Mark V and Speed Booster ULTRA II)|
|Emulates a Sony LA-EA1 or LA-EA3 lens adapter for A-mount lenses||Emulates, on a best-effort basis, a "native" E-mount lens|
|Video AF is always slow contrast-detect and requires half-pressing shutter release button to activate||Continuous video AF possible but performance may be unsatisfactory with some lenses; motor noise may be picked up by the camera's internal mic and an appropriately placed external microphone is required for video work|
|Some functions are unavailable||
DMF (direct manual focus)
Eye-AF (A7 series and A6300 only)
Zoom position W-T indicator (NEX-5R/6/VG20 or later)
Distance display (A7 series, A6300 and camcorders only with a lens transmitting distance information)
Auto-magnify (requires distance information from lens)
|Stop down when you fire the shutter||Stop down as you turn the aperture dial (if "LiveView Display" is configured to "Setting Effect ON")|
|Aperture movement kept to a minimum||Frequent aperture movements with increased tick noise from the aperture|
|With a variable aperture lens, the aperture changes whilst zooming but the iris remains constant. For example, if an F/4-5.6 lens is set to f/8 at its widest zoom position, the aperture will gradually become f/11 as you zoom to the tele end.||A variable aperture lens would mimick a constant aperture lens using iris movement. For example, if an F/4-5.6 lens is set to f/8 at its widest zoom position, the aperture remains at f/8 at any zoom position, but the iris opens up as you zoom toward the tele end.|
Lower power consumption
Higher power consumption
|Servo zoom with the lens' rocker switch only||Servo zoom of CN-E 18-80mm T4.4 L lens controlled from camera body|
In "Green" Mode, battery power is conserved by reduced aperture diaphragm movements. The aperture diaphragm will not stop down until the shutter release is fully depressed or the movie capture button is depressed. Image stabilization is not activated until the shutter release button is half-pressed or movie capture begins.
"Green" mode is activated by default for Smart Adapter II, III and the original Speed Booster. The original Smart Adapter (Mark I) supports only the Advanced Mode.
Changing Mode Temporarily
Choose the other operation mode by first turning on the power of your Sony NEX camera and either
attach the Metabones Smart Adapter onto the Sony NEX camera body first, and then while depressing the Wide-Open/Custom Function (WO/CF) button of the Smart Adapter, attach the Canon EF mount lens onto the Smart Adapter, or
attach the Canon EF mount lens onto the Metabones Smart Adapter first, and then while depressing the Wide-Open/Custom Function (WO/CF) button of the Smart Adapter, attach the Smart Adapter onto the Sony NEX camera body.
The operation mode is reset to default when either the Smart Adapter or the Canon EF mount lens is detached.
Changing the Default Mode Permanently
- With no lens attached, turn on camera body.
- While holding down the WO/CF button on the adapter, attach lens.
- Without ever releasing the WO/CF button, switch off the camera's power.
- Repeat to restore the default mode to Advanced mode again. With Mark I, Mark II, Mark III and the original Speed Booster, you may make the switch for only about 10 times. After that you can only make temporary mode changes. A firmware update will fully restore the capability to permanently change the default mode. There is no restriction on default mode changes with Mark IV and Speed Booster ULTRA.
Changing the Default Mode Using Metabones App
- You may change the default mode of Mark IV and Speed Booster ULTRA using Metabones App. Mark I, II, III and the original Speed Booster does not support Metabones App.
- Download Metabones App from the Metabones web site. It is available on the Support/Download page or any Speed Booster/Smart Adapter product page.
- Run Metabones App and follow the on-screen directions.
- There are 2 separate mode settings which can be set independently, one for newer cameras (A7RII and newer) and one for older cameras (A7II and older).
