The Olloclip iPhone Telephoto lens will be available in two versions - one for the iPhone 5 and another one for iPhone 4S/4. The lens will appear in Apple Stores later on this month and in Best Buy in August.
The package includes not just the lens itself, but a telephoto lens cap, microfiber bags, CPL/wide-angle lens adapter and iPod touch 5th generation adapter as well. If you can swallow the $99 price tag, that seems a great accessory to have in addition to the fish eye/wide-angle/macro 3-in-1 system.
