Manufactured from hard anodized machined aluminum, the Trio has two groups of lenses inside, one with a +5 diopter and the other with a +10. These two groups can be moved independently, allowing 4 possible levels of magnification.
With the the two levers in their upper position, there is no magnification, which gives infinite focus without any vignetting.
Activating the first lever gives a +5 diopter, and the second lever +10.
Both levers in the lower position gives an effective +15 diopter lens.
Mounts on standard 67mm threaded ports.
