There are versions of the #3 with different lens modules on them. I have two with the knurled ring on the lens being different sizes, but they both have the same dia. thread on the lens barrel.

<EDIT> I revised the following paragraph to reflect the new caliper measurements of the HD lens thread, which shows it to be closer to a 7mm thread, NOT 6mm as I previously estimated by "eyeballing" against a scale. <EDIT>

So, based on the measure dia. of the HD camera thread now being 7mm and not 6mm as I previously estimated, this would likely mean the #3 lens thread IS 6mm as you said.

Sorry for posting a visual guess rather than hard measurements in my prior posts!
