I've looked and can't seem to find any tutorials on using the NN4 with the Nadir adapter. I'm using a Canon 5K Mark III with the 16-35 lens for interior virtual tours.

I have been excluding the zenith and nadir shots, just shooting -30 and +30 (12 total shots) which works fine.

Curious how easy using the Nadir adapter is and if it's worth the extra work?

Thanks
