Used Isco projector lenses?

I recently saw on eBay a number of listing for what appear to be used Isco projector lenses intended for cinema use. Does anyone have any info on these?

Here are some examples:

I understand most of these have different ratios the you might want and specific focusing distance. 1.5x and 2.x are pretty commen compression factors but 1.25x (4k Sony JVC) and 1.33x (every one else) are what is turn key for home theater.

I think they’re too small for most applications too. Like, the light beam from the projector wouldn’t pass through these lenses correctly.

The first one is an integrated prime lens / anamorphic lens.

The second first one is not an anamorphic lens.


Both are designed for 35mm Film projectors, not video projectors.
