I was looking at some teleconverter lenses for my S5IS
Alan photo has one that is 3X and John3:16 has one that is 2.5X, these are their third party lenses.
I tried them on but both with different magnify show little enlargement. I tried with max zoom and no zoom and the magnification look the most 1.5-1.8 times zoom from my naked eye. So is this normal?
Or really to get a true 2x zoom power, I really have to pay more to get a canon original teleconverter lenses?
Expert please advice. Thanks.
