I upgraded from NEX 3 to NEX c3 and I found that the alignment for the NEX 3 is the same as the NEX c3.

Using the NEX VCL-ECF1 fisheye adapter, I think that 6 around at 15degrees down + zenith at 65 degrees up and a nadir patch will work just fine.

But the NEX c3 is a lot smaller and lighter. Just thought I'd mention it.
