With the retaining clip to attach the converter lenses are mini quickly and safely both on iPhone 4S and the Ipad. Here the focus is only modest and is more reminiscent of a Lomo camera, which is good for fun photos. In comparison, an 8x Tele-converter for the iPhone 4S, which I have for about 2 years, even been on a South Africa Safari will be able to create appealing images when played back on a 104 cm high-definition TV. For wide-angle images are recommended when more appropriate Iphone apps, especially those that can kombineren together not only horzontal partial images composed (that delivers on the TV only filmstrips low altitude), but horizontal and vertical fields.
