Try pressing those buttons on your keyboard:
End
Home
Ins
If none of these help with your camera try editing config-cache.wtf in your wow/wtf/Account/*your_acc_name*/*your_realm_name*/*your_char_name*/ and edit those lines
Code:
SET cameraSavedDistance "48.000793"
SET cameraSavedPetBattleDistance "15.001"
SET cameraSavedPitch "57.699957"
to be someting like mine
If it's till bugged just delete wtf and cache folders from your wow directory
if it's still bugged try typing on of these this in game:
/script ResetView(1)
/console CameraDistanceMax 50
/script SetView(5);SetView(5)
