>>3379410It's not different at all. It's just that on larger sensors you get more bug in the shot at same magnifications. Magnification scales are universal across the sensors.
It's not that hard figuring what you're getting with a clip on, you just shoot a ruler like that anon told you. Say your sensor is 10mm wide and you get 10mm, then you're at 1:1. If you get 1mm you're at 10:1, if you get 100mm, you're at 1:10, and so on.
>>3378903 for example, would be impressive 7,8:1, provided it's in mm and uncroped. Now, you'll often get better results at 1:2, or even lower magnifications, it's just matter of what's best at the moment. The main use for magnification scales is plain documentation. If you note at what magnification a shot was taken. Then you'll know near precise size of the bug. You need to be in manual focus, and know your lens, but it's perfectly doable even on lenses that don't have magnifications written on them like this one.
