The Opteka T90 0.7X HD Pro Series Wide Angle Lens for 72mm & 82mm Camcorders works with any HD camcorder lens or HDSLR lens with a 72mm or 82mm filter size to increase its angle of view by 30%. Great for expanding what you can show in a tight interior scene without knocking out the back wall, or for widening that already panoramic vista. Increase perspective by making background objects look even more distant from foreground elements.
A high-quality wide-angle converter is a convenient way to expand the versatility of your kit without breaking the bank by buying another, wider lens. For its part Opteka has gone to great lengths to ensure that its 0.7x converter's optical quality is indeed high: it features three top-of-the line multi-coated glass elements to deliver ultra-sharp HD images that are free of unwanted distortion or chromatic aberration.
The T90 0.7x lens includes step-up rings for both 72mm and 82mm thread sizes.
