Schneider Optics has added a 2X Tele lens to its iPro Lens System, which enables users to capture professional photographic still and video imagery with the iPhone 4 and 4S.
With this new lens mount, phone users will be able to extend their focal length to about 60mm (35mm equivalent).
The iPro System features a black iPhone case with a bayonet mount to allow iPro lenses to be quickly mounted and interchanged.
Previous models of the iPro Lens set sold for a list price of $199 and included the iPhone case, fish-eye and wide-angle lenses, and handle/lens case.
The new iPro 2X Tele lens sells for around $100.
