randomly this variants
1. Trap focus -> continuous -> set -> HlfShutter -> led permanently shines -> {trap focus ok}
2. Trap focus -> continuous -> set -> HlfShutter -> short led blink -> {no trap focus} -> HlfShutter -> led permanently shines -> {trap focus ok}
and then
{trap focus ok} -> shutter halfway (
http://wiki.magiclantern.fm/userguide#trap_focus) -> {nothing, trap focus continues}
randomly problem with photos taking on focus:
{trap focus / both variants) -> (slow focus changing or object position changing)-> {focus taken - beep} -> {nothing, no photo}
edit:
problem with camera start with active trap focus
1. (camera on with trap focus continuous) -> (longer waiting) -> press trash button -> {nothing, only blink} -> menu button -> {nothing, only blink} -> menu button -> canon menu
2. (camera on with trap focus continuous) -> (longer waiting) -> press trash button -> {nothing, only blink} -> menu button -> {nothing, only blink} -> longer waiting -> menu button -> {nothing, only blink} -> menu button -> canon menu
.. canon menu -> trash button -> nothing -> menu button -> canon menu left -> trash button -> ML menu
