Different applications require different solutions. Nuclear applications require the zoom to be radiation resistant utilising special glass types to avoid discolouring when exposed to radiation.
Zoom tracking is important when users want the subjects always in focus even when they are zooming in or out. A tracking zoom lens does not require auto focus once tracking is set and a well-designed tracking zoom will maintain good resolution and focus throughout the zoom range. The Resolve Optics tracking zoom lens ethos is to combine all these qualities with a mechanical design optimised for a specific application without compromise.
