RF 50mm f/1.2L USM vs 28-75mm f/2.8 Di III VXD G2

Lens mount is a categorical spec — values are distinct options rather than points on a continuous scale. Higher-tier options are not always strictly better; they often trade one capability for another (more protection at the cost of weight, more performance at the cost of efficiency, more features at the cost of complexity). Read the option names as shorthand for a bundle of tradeoffs rather than a simple ranking. When two products report different values, the right pick depends on how you'll actually use the device: a higher rating you'll never benefit from is wasted, while a lower rating that matches your environment can save money without compromise. Where the category has a clear "best" tier — IP68 for water, OLED for displays — the Mars Score reflects that, but a one-step difference between adjacent tiers is rarely decisive on its own.
