No wonder here - the TC uses only the central part of an image circle

If a 1.5x TC is taking the image from a APSC lens & spreading it to fit a FF sensor it's effectively using all the lenses image circle.

Never heard of a 1.5x TC, all I've used are 1.4X.
I was surprised it worked so well, considering there is an extra number of glass elements in the light path. Much better than using the same Kenko TC on a DX body, for instance!
I expected some vignetting, but I could not notice any.
