This is a Contax standard lens, the Carl Zeiss Planar 50mm F1.4. It's a beautiful lens with the renowned T* coating. Both the lens and the lens barrel are in excellent condition with few scratches or blemishes. There are some scuffs on the lens cap, but the lens itself has very little dust, and no mold or fogging. It's a Contax mount, but I've selected F-mount since there isn't an option for it. It's quite strange, isn't it, how things get mixed up on Mercari? Like "Workman" becoming "Walkman." I wonder if people don't notice the mistakes? Thank you.
