GDU 40mm Lens - does it move in/out on focus

[Daniel Reed]

Anyone out there with a Global Dynamics United (Jarred Land/FF) 40mm lens?

I need to know if the front of the lens moves in and out while focusing,
or if it moves inside the "armored precision machined mil spec 7075 Aluminum housing".

I'm interested in using it in a special case where the lens needs to be internal focus only and not change lens length even in the slightest


Thank You!

Moves inside. Nothing on the exterior of the lens moves.
