>>4373788Fuji 16-55mm f/2.8 ~800-900€ used
Snoy 24-70 f/2.8 ~2000€, even used. Older one is cheaper.
Olympus 12-40 f/2.8 ~400-500€ used. No bother looking at the mark ii since it's the same lens with some seals added.
Imagine using similar lenses for each system for these comparisons. I could make a picture with a 150-600 comparing it to the olympus 75-300 but even you'd see I'd be comparing apples with oranges.
