This is my first post to the forum. My interest is shooting at 24mm (on a 5D Mark III) with no flash. Nighttime cityscapes, museum exhibits, indoor group shots, poorly lit indoor events (e.g., cocktail parties, banquets), and outdoor evening events (e.g. social gatherings in patios, courtyards, backyards, etc.) would be the subjects. Would the prime lens be sharper at 24mm f/2.8 than the zoom at 24mm f/2.8?
I would appreciate ideas and opinions anyone might offer (cost is not a factor in my decision).
