If you need more lenses than your budget allows, Polaroid conversion lenses represent a cost effective and intelligent alternativeBecause our DNA is optics and lenses (as in Polarizing filters) our conversion lenses are precision engineered and multi-coated to provide flawless results regardless if you use them with your camera, camcorder or even HD-Video capable DSLR.The best part is that while using them is as easy as mounting them to your existing fixed or zoom lens, the results are nothing short of breathtaking.Case in point our Wide Angle and Fisheye converters give your lens a full panoramic perspective without any loss of detail plus their built-in macro-feature lets you ?convert our convertors? to an ?up close and personal? macro lens by simply removing a lens ring.Need a long telephoto lens but don?t want to deal with the expense (or the weight)? Just add one of our telephoto lenses to your lens and double, triple or quadruple your lenses focal length-or lengths (if you?re using a zoom lens!)In short, if you want the flexibility of multiple telephoto, wide and fisheye lenses without the expense or the inconvenience of having to carry them, put Polaroid conversion lenses in the picture
