many photographers and generated many questions, so we now engage our ControlTL feature of “Force TTL Master Mode” by 
default.
The on-camera ash now appears to the camera to be in <MASTER> mode all the time. All remote PocketWizard radios on the 
same channel will trigger. 
This mode enables the use of a 430EX or 430EX II in the shoe of a ControlTL transmitter as a master to trigger remote ashes. 
The transmitter tells the camera that <MASTER> mode is active even though that mode is not available or set in the ash. This 
also benets the 580EX (I and II) as they will emit fewer communication ashes. This reduces the “ickering pre-ash” that 
bothers some subjects. All ash controls remain active.
If you wish to retain the ability to toggle on and off your remote ashes using the <MASTER> control on your 580EX or 580EX II, 
you will need to uncheck “Force TTL Master Mode” in the Utility on the Misc Tab (alternate method: set your on-camera radio to 
an unused channel, like C.2, to have only the local ash re and not the remotes – make sure the C.2 channel is not in use by 
another photographer). You only need to change this setting for a radio used as a transmitter on a camera - FlexTT5 radios used 
for triggering a remote ash do not need this setting changed. 
When “Force TTL Master Mode” is engaged, toggling <MASTER> on the ash will not toggle on and off remote ashes. When 
you perform a factory reset after rmware upgrade, this mode will be engaged by default.
FlexTT5 Transmitter Only Mode
This mode has been greatly improved and is recommended when using a FlexTT5 as a transmitter on the camera. Without this 
mode enabled, other photographers could trigger your on-camera ash.  
Bug Fixes:
  •  Occasionally, the camera’s shutter speed would get stuck at X-sync if TEST was pressed and held for a long time (like when 
    triggering a remote motor driven camera). This has been corrected. 
  •  The ST-E2 on top of a MiniTT1 on top of a 5D Mark II, 1D Mark III, and possibly other cameras, would lose its settings when 
    coming out of sleep mode. This has been improved. Interesting to note, this behavior happened on a 5D Mark II with an 
    ST-E2 directly in its shoe (no radios involved). This rmware corrects that behavior.  
  •  Distance info on 580EX II not updating sometimes. This operation has been improved, but may still exhibit inconsistent 
    behavior. Recommended workaround is to set the ash on the camera’s radio to never sleep (disable Auto Power Off using 
    the correct custom function). 
  •  FlexTT5 as a transmitter on a 1D Mark III had inconsistent performance when adjusting ratios using a ash on top of the 
    Flex. This has been corrected. 
  •  5D Mark II performance with large aperture lenses improved. On wider lenses like the 50mm f/1.4 or 85mm f/1.2 there are 
    still narrower aperture settings that result in shutter clipping. This edited text from the 4.250 Addendum still applies:
    o  Due to special trigger timing considerations for this camera, some lenses will experience frame clipping (hard lines or  
      dark frames caused by the shutter getting “caught” by the ash) at mid to narrower aperture settings. Larger maximum 
      aperture lenses like f/1.4 or f/1.2 models are most affected and may start to see ash clipping as early as f/5.6. 
      Lenses with a widest aperture of f/3.5 to f/5.6 may not experience clipping at all. If there is no ash on top of the 
      ControlTL transmitter in the shoe of the 5D Mark II, results will be better. This aperture issue does not affect any other 
      camera we have tested. Please test each of your lenses across the full range of f-stops to be sure you understand the 
      limitations.
