This is a naive question but I want to solve it. Why my Lumix' ZS50 24-720 zoom lens show wider the images than my Sony's a6000 18-135 Sony lens, although the first is 24 wide and the second is 18 wide?
What's going on?
PS. First is Lumix and second is Sony
The Lumix numbers of 24-720 represent what a full 35mm sensor would see. The A6000 has an APSC size sensor which has a crop factor of 1.5. In other words if your 18-135 was on a full frame body like an A7 it would be 18-135 but the A6000 only sees part of the full frame which makes your 18-135 look like what a 36-202.5 would on a full frame sensor. Your pictures represent the field of view of an 18mm and a 36mm lens on a full frame camera.
