Now, I will fully admit that I try to get my head around the whole FF versus APS-C and focal view equivalence thing but sometimes it goes around and around in my head so much that I probably end up confusing myself more in the end than I was at the beginning.

the other thing to keep in mind is pixel density; higher pixel density can make the photo look bigger when viewed at 100% size on your monitor.

24mp aps-c sensors have higher pixel density than, say, a 36mp ff sensor... so if you did crop an aps-c frame out of a 36mp sensor, per the photo posted earlier, it wouldn't be a 24mp photo, it would have less pixels than that, because 36mp sensors have lower pixel density.

so it's not all just about aov(angle of view); higher pixel density makes ff lenses on a 24mp aps-c sensor seem like they have more reach, because of the higher pixel density.

of course, higher pixel density means smaller pixels, which is a whole 'nother discussion... everything in photography is always a tradeoff of some sort.
