Hey bob,

your little DIY sounds fantastic, but i followed all the instructions and seems i aint getting it to work for some reason. I do get a variable resistance between the base and the center between 4-5 KOHMS when adjusting the POT, but it seems that the plug doesnt override the camera, does nothing actually. Tested with camera both manual and auto focus. Any ideas or anybody else who has built one?

thanks,
stephen.

Stephen,

I would really check to see if is plugged all the way in. I sometimes have trouble with the plug on my HVXs. Also, you would know if it is plugged in because the camera will say that it is in manual mode.

bob you were right, needed an extra push, this thing sure is flimsy without a cover. just realised though my range is off so will have to experiment a little with the resistors. thanks!

Here's my version on Bob's original. I found a different type of 1K POT that can be adjusted with a small philips screwdriver to adjust the focus. I'ts in series with a 2.7K Ohm 1/2W resistor, enclosed in a 1/4" female jack case cut to size connected to a 1/8" right angle stereo jack. This can vary from camera to camera as Bob said. Doesn't obstruct the record button and works like a charm!
