Relay lens for HD100?

For what its worth, I have used the Century Optic 58mm 7+ achromatic dioptre with a 72mm adaptor ring on it for relay into Z1P/FX1.

I also used it rather crudely mounted on front of a HD100. The image appeared fine but I did not subject it to critical testing.

I used the 82mm thread in the fixed lens hood mount of the standard lens to mount my adaptor and wedged the 72mm filter thread of the dioptre into one of the flutes around the front element of the lens itself.

Putting the dioptre on the lens hood mount is not going to work as the lens focus barrel moves forward or back and changes the distance between the dioptre and front element of the standard lens when focussing.
