Wow - that guy is asking $1750 for that lens. I paid $50 for mine. Somehow I don't think he's going to get the $1750.
I've been googling on this. It seems the market for these broadcast video lenses has collapsed because nobody wants lenses that aren't designed for HD.
But I'll bet the better ones still work pretty well at HD, depending on the pixel pitch of the sensor. At $50 it's a toy I can experiment with.
Jon - here's what I've learned so far:
1 - The flange focal distance (flange to image plane, aka 'register') is supposed to be 20mm, which matches what I measured. To mount it on a camera with an adapter, you need a camera with a flange distance shorter than that, to allow some room for an adapter.
20mm rules out all standard DSLR bodies. According to http://en.wikipedia.org/wiki/Flange_focal_distance,
the only mounts with a flange distance less than 20 mm are:
Micro 4/3, 19.25mm
Sony E-mount (Sony NEX), 18mm
Fuji X-mount (Fuji X10), 17.7mm
C-mount (video/cine), 17.52mm
Nikon CX (Nikon 1) mount, 17mm
Pentax Q mount, 9.2mm
2 - The image circle is designed for a 1/2 inch CCD (4:3), which is 8mm diagonal. See the attached spreadsheet I made (info collected online) - according to that, the ONLY modern interchangable lens digital camera that won't vignette with that lens (because the sensor is < 8mm diagonal) is the Pentax Q. (Which I think is a crappy camera.)
So the compromise I'm thinking of is to mount it on a Nikon V1 or J1. It'll still vignette like crazy, but I can crop afterwards. Micro 4/3 should work too, but the pixels are so big and the sensor is so large compared to the image circle, that I think there won't be many pixels left after cropping.
3 - There do seem to be a few adapters out there. But they are incredibly expensive:
Here's one to adapt the JVC 1/2" bayonet to Nikon - it's $590 (!!):http://www.bhphotovideo.com/c/product/77577-REG/Century_Precision_Optics_0LA_N120_00_LA_N120_Nikon_to_1_2.html
And here's one to adapt it to C-mount - $424:http://www.bhphotovideo.com/c/product/77584-REG/Century_Precision_Optics_0LA_12BC_00_LA_12BC_1_2_Bayonet_to.html
(C-mount adapters for cameras are easy to find and cheap on eBay.)
Those are the best prices I found.
Since I only paid $50 for the lens, I'm not going to even consider those.
The mount is attached by 8 screws. I think I'll try to take it off and see if I can jerry-rig something...
