listing ended, now it's back at $35.  I ended up buying two at the earlier price.

Yes, this is why I was planning on using at least one of these as a finder. I have an 11mm cmount lens on my old color flea, and it's a terrific finder, though a bit wide angle. The 6mm would be wider of course. But I still have an old 3com home connect camera that came with 3 lenses of different fl. I'm hoping I can use one of those. 

I also have a Phillips toucam with a 1 1/4" adapter in it that could be used to put one in an off axis guider. 

The case on these must be threaded for the c mount adapter option. I might also try machining a 11/4" adapter to mount directly to the case, and take out the 6mm lens and mount entirely. 

I made an offer for 5 cameras, but the price is so good I should have just hit the bin button from the get go.

Thanks for pointing that out.

I had another look at the image and it looks like the lens is sitting in a "M12-0.5mm" mount. To remove the lens, just unscrew it all the way.

I also just checked the "Technical Reference manual" for the FireFly MV and they do list the lens mounting assembly for the board level cameras as "M12 Microlens Mount".

You can buy M12x0.5mm to C/Mount or 1.25" nose piece adapters too.

The cameras can be run in 8 or 16 bit (10 bit actual delivered) and have 6  micron square pixels.

They run as high as 210 fps in Format 7 ROI's 160x120.

HTH..

One thing to note is that there is a 6mm lens attached in front of the

sensor.  The photo on the eBay site shows the lens and the seller reposted

w/ mention of the lens after I made an inquiry.  Apparently these were an

unwanted custom order that the seller picked up.

I don't know if the lens can be easily detached or what effect the lens will

have.  Also the photo on the PGR website shows the PCB and sensor are

encased but for these the PCB is exposed.

I have ordered three, figuring these are cheap enough to play with.

I believe there are more than 400 for sale, so I'd suggest anyone interested

to hold off until someone can verify these are actually usable.  I'll repost

in a week or so when I've had a chance to check them out.
