OK, Here is an image of me getting focus. I set the 1/2" bold directly in the water drop path then focus on the threads at the height of the umbrella. It is pretty straight forward. The setup uses 3 high speed canon flashes set at 1/64 power which gives about a 1/24000s pulse which is enough to stop the action.
You can ONLY do this (in the OLY line) with the E-P1 or E-P2 cameras because they are the only ones that have a remote shutter cord hookup. The E-PL1 doesnot and I have that camera converted to Full Spectrum Infrared.
The timer connects directly to the flashes then to the camera and Drop Kit.
I push a button which releases a drop, starts 2 timers (flash and Camera). Timer 1 opens the shutter, Timer 2 fires the flashes. The key is to adjust the timers, water color, drop size flash delay and so on to get unusual images. It takes about 20 drops to setup the timers.
The E-P2 works quite well. The 14-150 is very sharp (set at about 100mm) with the Canon 500D closeup filter.
Here is a
link to the Time Machine.
The 2 images here are of the setup and the focus aid. The setup shows the Canon 1DMK3 and 90TS-E lens. I later changed out that camera in favor of the E-P2 which worked very well.
