I've recently bought a 14mm rectilinear lens for my Fujifilm X-T1. I've tried shooting with 8 shots around, 3 rows (+45°, 0°, -45°)+ Zenith(+60°) and Nadir. Total of 26 shots. This seems to work OK but I thought I check to see if anyone here with more experience shooting at this focal length has found a better setup.
For example, would 3 rows (+50°, 5°, -40°)+ Nadir and no Zenith (total of 25 shots) work well?
