Poor trigger sensitivity with Canon 5d MkIII and 7d Mk II
I'm connecting my LV5 to the Canon 5d MkIII and 7d Mk II directly with a short (3') cable. Very short beam interruptions, such as a rapid wave of the hand to disrupt the beam, won't trigger the shutter. It takes a longer disruption of the beam to trigger. I have the emitter set to 1 kHz, which is preferred for quick action. While testing the device with rapid beam disruptions, the sensor LED briefly flashes red to show that the beam has been disrupted, but the shutter does not engage. To capture a bird flying rapidly through the beam, I need greater sensitivity response. A rapidly flying bird may not trigger the shutter. Shouldn't the shutter engage reliably every time the beam is disrupted, regardless of the duration of the disruption? I'm wondering if I got a defective device, or if the device just can't deliver the responsiveness I need to capture birds in flight.
