I'm trying to raise funds for my indie TV show Infinite Simulations. The lens is very good build and optical quality. It came with my Mokose UC70 1/1.8" sensor USB 3.0 4k webcam. I don't want to sell it but I have two and need the money. It's a 1/1.8" sensor format so it will work with 1/2", 1/2.3", 1/2.5", 1/3", etc sensors. The aperture is only f/2.8 but it's nice and sharp and it's f/2.8 through the entire zoom range. You can get a good bokeh out this lens when zoomed in. The C Mount lenses can also work with CS Mount lens but not vice versa. It comes with the C Mount to CS Mount adapter.

This lens works perfectly with a Mokose C100 4K camera, which has a sensor with film-like noise and is a very interesting cinematography tool that can be rigged out like a cinema camera for cheap.
