A remarkable lens from Japan, very sharp wide open, of the famous zeiss inspired design with preset aperture. It's well made, all glass and steel, with excellent color and contrast. The optics in this lens are amazing, it is simple and it works. It's bokeh and colour rendering are brilliant and it's as sharp as a razor. This is one of the mythical lenses of the days of lore, and hard to find even on ebay. There is about 340 degrees of rotation on the focus ring. The lens came with a 2X adapter as well. This series of lenses (model 680) were made between 1962 & 1969. The included tele converter is shown in the picture. This gave the kit the twin tele name.
