Why does the same product look different in my shot than it does in an example from a different studio?
We're talking about perspective here. How far you are from your subject affects the way your subject's proportions look.
Try shooting the same thing with the 18-135, say at 135 mm, but this time ...

The source of the distortion is the camera’s viewpoint. A combination of subject distance and the angle-of-view, delivered by the chosen focal length of the lens, produced the distortion. Your ...
