hello,

i have a Canon 500D, which is was trying to take some night landscape pics. so i thought i would use standard ideas of using mirror lockup along with my hahnel wireless remote to control the exposure in bulb mode and thus take as much shake out of the equation. When i tried to fire the trigger remotely the camera decided to both open and shut the lense almost instantly. I tried a few more times in case i was being a muppet but the same thing kept happening, once i had disabled the lockup function from the menu the camera returned to normal remote mode. The remote trigger is a hahnel giga t pro two.

did i do something wrong? how can i correct this?
