If you use a Samsung Galaxy S4 and consider yourself somewhat of a smartphoneographer, check out the Ztylus Camera case and RV-1 Revolver Lens Kit which will effectively turn your phone into a multi-lens digital camera. We’ve seen lens attachment accessories before, but the Ztylus is a little different because it completely replaces the back cover of the S4. Just unsnap the cover, snap the Ztylus in place and now you have added a handy ergonomic hand grip, threaded tripod mount, 2-way stand, speaker enhancer and two eyelets so you can attach your favorite strap. The Ztylus case can be used alone, but when it is paired with the removable RV-1 Revolver Lens Kit, it adds 4 lenses to your phone: CPL(Circular Polarizer Filter), Wide Angle Lens, Super Micro Lens and a Extreme Fish Eye Lens. The case and lens kit can be purchased from Ztylus separately for $29.99 and 59.99 respectively or together for $84.99.
