F0.7 lens? Is it big enough to strap on a K body, or Q only?

Did I catch your attention?

It would be mostly useless on any camera except a thermal imaging camera, germanium is opaque to visible light.

This one is only slightly slower, and probably transparent:

No focus or aperture controls, what - you just have one focal distance to shoot ?

Some of the images seem to show visible light:

How many stops slower is f0.95? I'll sell this one for $1000:



It has 8 blades, an aperture ring (smooth, no click stops) but no focus or mount.



OK, $800 because it's not mint.

About 0.8 or 0.9 stops.

That makes my price a reasonable number. One example, the price difference between an A50/1.2 and an A50/1.7.

No PMs yet, but it's bound to go fast!

No. It just is equivalent to a 50mm f/1.9 lens on a FF sensor. f/0.95 is f/0.95.

Is there any indication that this f/0.7 lens can cover a large sensor? Can it even cover MFT?

Better save a bit more and get the real thing - the Leica Noctilux. Or get SLR Magic's version for less than the price of this junk.
