HTC Teaser Suggests HTC One Smartphone Could Support Canon Lenses

Next Tuesday (2/19 2013) HTC is supposed to announce their new flagship smartphone, the HTC One. Since some time, they are teasing specs and features of the smartphone via Twitter. Yesterday they tweeted the image you see above. You can see the date of the announcement in green letters around the edge of the lens. The brand name is blurred out but it is easily identifiable as a Canon 50mm lens.

What does the teaser suggest? Speculation is that the HTC One could support a DSLR camera lens add-on. The image shows a Canon lens. Will the HTC One be able to use Canon lenses? A handset with interchangeable lenses?
