Contax (Carl Zeiss) 180mm prime lens, T* coating. C/Y mount from the film era (the C/Y mount option was not available in the size selection on Mercari, so it is listed as EF mount, but it is different). ND4 and P filters are included. No hood, lens bag included. Purchased used for just under 30,000 yen and used a few times. When not in use, it was stored in a dry box. I think there are no noticeable signs of mold, dust, or debris. The front lens cover has become whitish. I am an amateur, so there may be oversights, but please consider this with your understanding. - Model: Sonner 2.8/180 - T-value: T* - Aperture blade shape: Hexagonal - Focal length: 180mm - Maximum aperture: f/2.8 Thank you for viewing.
