The MT-24EX'seffective flash distance range greatly depends on the position and angle of the flash heads. For best results, point the flash heads directly at the subject and use FE lock (~ p.30) and modeling flash (~ p.29, 55).
When the correct flash exposure is obtained, the flash exposure confirmation lamp lights (~ p.16).
The MT-24EX has nine Custom Functions from C.Fn-1 to C.Fn-9.C.Fn-1 to C.Fn-7 are the same as the MR-14EX's(~p.65), and C.Fn-8 and C.Fn-9 are described below.
