Speedlite 580EXII

Mounting a 580EXII on a T3i & shooting in P.  Flash will inexplicably switch from ETTL mode to TTL, overexposing closer subjects.  Cannot reset to ETTL manually.  Must shut down, remove flash from camera frame, remove batteries and start again. Any thoughts or solutions appreciated.

Hi Jchafitz, thanks for posting!

We just wanted to let you know that we don't recommend do-it-yourself repairs. If you’re experiencing a problem with your Speedlite, it’s best to let a professional Canon Factory Service Center Technician do the work to keep you and your gear safe.

One final missive, and then I will call it quits. Too much to do. From the Canon 80D Online Instruction Manual (printed version does not have section on flash photography).

SETTING THE FLASH OUTPUT MANUALLY FOR WIRELESS SHOOTING

 

When [Flash Mode] is set to [Manual Flash], flash exposure can be set manually.  The flash output settings that can be set vary depending upon the setting.

 

Firing Group:  All  The manual flash output setting is applied to all external Speedlites.

 

Firing Group:  (A:B)   You can set the flash output separately for Slave Groups A and B.

 

Firing Group:  All and Built-In  The flash output can be set separately for Speedlite(s) and built-In flash.

 

Firing Group:  All, (A:B), Built-In   You can set the flash output separately for Slave Groups A and B.  You can also set the flash output for the built-in flash.

Maybe you can set it, but the information does not appear on the Speedlite LCD Panel.  (If this is the case, Canon should have made that clear).  I had to type all the above in by hand because the PDF version of the online manual would not allow me to cut and paste.  Maybe Canon needs a better tech writer who goes into more detail.  There are entirely too many "unknowns".  I hope Syl Arena's new book comes out this summer . . .

 

Thanks for listening.  No need to write back, but it was interesting sharing.  On to many other things to do . . .

I lied. Your built in flash is a master.
