Contax Makro-Planar 100mm F2.8 AEG, made in West Germany. This is a pure 1:1 macro lens with a minimum focusing distance of 0.41m for 1:1 magnification. It's also said to be good for portraits, taking advantage of the bokeh. As a lens made in West Germany, I think it's a good lens both for collection and practical use. It has been stored in a dehumidified, auto-clean dry cabinet since I acquired it. ● Brand Contax CONTAX ● Item ・Makro-Planar T* 100mm F2.8 AEG Color: Black Mount: Yashica/Contax mount (YC mount) Lens Construction: 7 elements in 7 groups Minimum Focusing Distance: 0.41m (1:1) Attachment: φ67mm screw-in Made in West Germany Lens Accessories: ・Front and rear caps ● Condition Beautiful condition.
