Go to: C:\Users\YOURWINDOWSUSERNAMEHERE\AppData\Local\SWTOR\swtor\settings
(alternatively you can type %appdata% into the start menu, and then go back to Local)
Then you want to select the file named: UserName_Account
UserName = your login name for your SWTOR account.
The file should have:
Movies_SeenMovies = 504
cabf_length = 4
cabf_1 = 53017890000067
cabf_2 = -6701356245527298048
cabf_3 = 3516185409073185599
Controls_CameraMaxDistance = 25.0
VolumeMaster = 19.9275360107
VolumeMusic = 19.1123180389
GUI_RaidFrameMaxHeight = 244.100067139
GUI_RaidFramePositionX = 316.801177979
GUI_RaidFramePositionY = 520.106140137
GUI_RaidHealthHeight = 23.6695652008
Controls_AbilityQueueLength = 0.5
GUI_RaidHealthWidth = 118.429344177
cabf_4 = 204
The line "Controls_CameraMaxDistance = 25.0" is the one you want to edit.
Select values of 1.0 to 100.0 (think of this as a percent, and include the ".0"). I've found that 40+ is wayyyyyy to far, so I use 30.0 myself.
After you've adjusted, save and exit, and launch the game and enjoy further zooming out of your camera.
If you have any questions just post em here, or talk to me in game.
