Although the camera of the iPhone 4 terminal is considered to be one of the most popular and most used cameras for smartphones, a lens has recently been released that can be attached to the camera of the iPhone 4 terminal and allows the acceptance of quality pictures similar to those taken with a DSLR camera. The accessory can be ordered in 2 formulas, one with a Nikon lens and one with a Canon lens, each of them being sold separately and can be attached to a case in which we have to mount the iPhone 4 terminal.
Telephoto, wide angle, macro, or your fixed fifty lenses all attach to this mount giving you a full range of lenses at your iPhone lovin' fingertips. Heck, you could even throw on a Diana adapter!
Of course, the pictures will not have the same quality as those taken with a DSLR camera, but such a nearly $200 accessory will help iDevice owners to take professional pictures using their own terminal. The iPhone SLR Mount can be purchased from here for $190.
