Konkan, India.
As there are no good ND filters available for fisheye lenses, long exposure has to be acheived in a very short duration.
I use my trusty 10-20 sigma with 10-stop B+W ND filter for long-exposure when the light is enough. Once ND filters are not required, I switch to the fisheye - to get the best of both worlds :)
