Have ordered this lens (Rokinon 12mm f2.8 fisheye lens, FF) from AMZ (on sale - 20% off on Prime Day). I'll use it with D3500. Before arriving, need helps to clear some potential obstacles when starting using it:
1. What is the correct focal length to calculate hyperfocal distance I should use with D3500 -- 35mm equivalent (~18mm) or real focal length (12mm)?
2. Can you set aperture by the aperture adjustment ring on this lens (no need on d3500 body)?
3. What is the reference line of distance scale below the focus scale ring? How do you use it to help focusing?
4. What is the best (preferred) ways to focus with this lens for different shots -- landscape, architecture (inside, outside), close-up, night sky (MW, etc)? -- e.g., set to the infinity mark or use hyperfocal distance for MW shots?
Thanks for your help.
