I was poking around on B&H and stumbled upon this CCTV lens, designed for the M4/3 mount. It is a very intriguing 20-70mm/f1.5 zoom lens. Weighs about 1 kg. Costs $700, which is hardly outlandish for what it is.

Has anyone else seen or heard of this lens before?

The same company also makes an 8.5mm/f2.8 for $367. Very reminiscent of the Kowa option, though probably not as good.

Both appear to be ruggedized and designed for extreme environments.

The datasheet on the Dahua website says it's only designed to resolve 12MP (it appears to be designed for 4K video), so I suspect the results wouldn't be nearly as good as just slapping a Sigma 50-100/1.8 on a Speedbooster, especially since you get AF (though it's a similar focal length for about half the weight...)

Very curious, nevertheless...
