This is a Vivitar 135mm f2.8 circa 1973-74 lens that I had AI converted by Pete Smith formerly a Nikon specialist at Photocamera Repair (which I believe is no longer in business). He converted the lens by machining out some of aperture ting and drilling and tapping a small post to engage the camera's AI ring lever. Very clever and works like a charm. The lens is in excellent condition and is small but hefty. Glass is perfect, no marks on body much except for some tape residue (see photos). Focuses to under 4.5 feet, aluminum on brass helical is still buttery smooth after all these years, Eight-blade aperture is clean and snappy. 55mm filter size, built-in black flocked lens shade, original caps. $32 with free USPS Priority Mail shipping to lower 48 states.
