    Here is the one I just built. I think it's working but I'm unsure. What exactly should I be looking for. I did notice it immediately focused.

    Something is off. Using the autofocus puts the focus at 30 and the back focus at 4.8 but when I plug the thing in all I get is a focus of 26 and a backfocus of 3.2 and it won't change even when I turn the screw and it is of course, out of focus then.

    I did find this video which was very helpful:

    I have successfully built two of these adapters now. My first has a limited range of between MF66 - MF71. It was made with a 1K pot and 3 resistors (2x 5.6K & 1x 1K) I no longer need it as my adapter has a new lens mount and the range no longer covers my adapter. I need MF61 now.

    My second I made this evening. It has a 5K pot which makes the useable range much wider, but tuning the focus requires fewer turns of the pot. It is combined with 2x 1K resistors & 1x 5.6K resistor, making a total of 7.6K to 12.6K resistance, which results in a DVX100B MF range of MF38 to MF70. Much more useful. I have a long 35mm adapter and need MF61/MF62.

    If you use a 1K pot, you have to loosely solder together resistors to get very close to your desired MF value. With a 2K pot you'll have a bigger range. With a 5K pot you get a huge range. It is the way to go, I think.

    Also, I used a good right angled Neutrik 3.5mm jack with a 10cm wire to the resistors block, so that it would not be resistant to breaking off in the socket during use. The pot and resistors I Epoxy-resined to form a strong unit with no chance of a connection failure at the solder joints. Araldite is a good insulator.

    If anybody needs MF66 - MF71 on a DVX100B, let me know. I have a nice little unit for that value.

    All the best

    Got any pics of the unit - sounds nice.
