Peleng Lens is a super wide angle photographic lens of "FISHEYE CIRCULAR" type. The Lens has a feature of diaphragm presetting which increases photographing efficient. The lenses have anti reflecting coating. The image being received by the Lens in film camera represents the circle of 24mm diameter. It occupies only part of frame 24x36 ( film or standard digital matrix) and fits in a small side of a frame with a small cutting along the edges. You may always crop these small black corners from your image. Image gives you full circle coverage for the full frame ( full matrix ) digital cameras. The geometric centers of the image and the frame coincide.
Peleng is an "old school" lens and has manual focus. Focus to infinity is a good option for landscape images. Peleng multi-coating optical glass serves to decrease reflections.
