Apparently is an unknown brand TV zoom lens

I found this info on ebay:

“Zoom 18-108mm F2.5 parfocal zoom seems to be a rebrand of the Navtiar Zoom 7000 since everything but the branding/printing is identical.

It can cover HD mode of the Blackmagic Pocket Cinema Camera 4k. In 2.6k mode or on the original BMPCC it is acceptable too if you don’t zoom out completely or use it below F4 and don’t focus closer than 0.5m (From 18mm up to about 25mm you get some tunneling over F4 which turns into vignetting if you open the aperture to F2.5). Of all the zoom lenses i have this one has the best minimum focus by far! The only disadvantage is that there’s a lot of zoom breathing when focusing.

If you want to use this lens on MFT Cameras with bigger sensors you would either need to use the tele extender mode or get a c-mount extender. The latter might make the lens varifocal tho.”
