 the differences.
Why should I care?
The idea of equivalence gives you the tools to understand the difference in performance between different camera formats in terms of depth-of-field. It also lets you relate the role of F-number and sensor size to how much light the camera will have access to, which is an indicator of likely low-light performance.
Ultimately, though, it's unlikely to make much difference to your day-to-day shooting: you can't try to flood a small sensor with extra light in order to get better images, because it'll just overexpose. But it's a useful thing to understand, when considering the size/price/image quality/depth-of-field trade-offs that you make, whenever you buy a new piece of camera equipment. There's no universally ideal 'sweet-spot' to that trade-off: but understanding equivalence can help you work out which balance is best for you.
• In low light, equivalent aperture can help you get some idea of noise performance and where the aperture of one camera can help offset any sensor size difference.
• Differences in sensor and lens characteristics mean that, while it gives a very good guide, equivalence doesn't give a precise prediction of performance.
