I have few basic question regarding lens aperture

1)Is it worth to upgrade from f4.5 to f2.8 or f1.8 to f1.2 for capturing non movable object (shutter speed can be reduced)

2) Does both f1.2 and f1.8 produce same quality image at f3.5 or higher (same ISO & same shutter speed)?

This question has not been answered yet.
