Contax Tessar 45mm F2.8 MMJ, made in Japan. This is a very small pancake lens, with a body height of only 18mm. Known as the "Hawk's Eye" Tessar, it is said to produce extremely sharp images with high contrast. It has been stored in a dry cabinet/auto-clean dry box since I acquired it. In addition to the front and rear caps, it comes with a genuine 49-55 ring, a HAKUBA P filter, and a lens cap. ● Brand Contax ● Item ・Tessar 45mm T＊ F2.8 MMJ 　Color: Black 　Mount: Yashica/Contax mount (YC mount) 　Lens Construction: 3 elements in 4 groups 　Minimum Focusing Distance: 0.6m 　Attachment: φ49mm screw-in or φ55mm screw-in using the 49-55 ring 　Lens made in Japan Accessories: ・Front and rear caps ・Contax 49-55 ring ・HAKUBA XC-PRO EXTREME LENS GUARD φ49mm ・HAKUBA Lens cap φ55mm ● Condition Beautiful condition.
