AEO MultiTrigger Pro Nature Trigger Micro Series Version 3.0
The AEO MultiTrigger Pro 3.0 is a dual mode Lightning Shutter Trigger / Motion Sensing Trigger
combination. Mode selection can be made by setting the Mode Slide Switch to either “Lightning” or
“Motion”. Enhancements in our “Pro” series triggers include both a sensitivity over ride adjustment, a
locking hot shoe / tripod mount., and improved ambient noise filtering (shutter hammer from 60Hz
sources).
Lightning Mode:
Test your new device right out of the box: Set the mode switch to “Lightning”. Turn the power on. The
red LED will flash every time the device triggers. It’s normal for it to trigger once on power up. If it
continues to trigger, check for light sources leaking into the room. (If you cover the window of the
device with your hand, it should not trigger). Set off a camera flash (using another camera or a flash
attachment). The flash should trigger the device.
Manual adjustment of the sensitivity is accomplished by adjusting the “trim screw” accessible on the left
side of the device (looking from above). The port in the most aft position is the sensitivity adjustment.
(The “forward port” is your cable connection). The Sensitivity Trim is a SINGLE TURN adjustment.
CAUTION: DO NOT ATTEMPT TO FORCE THE ADJUSTMENT BEYOND IT’S MECHANICAL STOPS. DOING SO
MAY DAMAGE THE SENSITIVITY ADJUSTMENT. Use a small jewelers screwdriver standard or Phillips) to
make the adjustments. Full CLOCKWISE sets the sensitivity at 120% of the factory set point. Full
COUNTER CLOCKWISE sets the sensitivity at 20% of the factory set point. We recommend for most
situations to use the normal set point which is approximately ¼ turn CCW from the full sensitivity point.
Other photography scenarios may dictate different settings at the professional photographer’s
discretion.
Theory of Operation:
The device triggers on the first bolt it detects and activates the shutter release of your camera within
0.1ms. Most lightning events last several hundred milliseconds
Photographing Lightning is as much Art as it is Science. Getting the right conditions and settings can be
challenging, and some folks have a better knack for it than others. But to get you started, here are some
basic “recommendations”:
1. The camera should be mounted on a tripod. You want it stable during the exposure.
2. Mount the device in your camera’s hot shoe mount with the red semi-clear window facing the
direction you are photographing. Insert the supplied plug into your camera remote shutter
interface.
3. Point the camera at the storm or in the direction you see lightning activity.
4. Set your Auto Focus feature to OFF or Disable.
5. Set the focus to infinity. (If the lightning is closer than that, you’re too close to it!!!)
6. We’ve found that when photographing lightning at night, an f-stop of 5.6 works well.
7. Shutter speed should be long for night shots, 2-10 seconds. For daytime shots, don’t exceed 1
second and you’ll need a smaller aperture/ larger f-stop as well.
