Carl Zeiss Contax G Sonnar T* 90mm f2.8 Lens

Selling my old 90mm f2.8 ZEISS Contax G lens.

Includes GG-3 metal lens hood, and GK-41 front lens cap, and a rear lens cap. No box or instructions.

Condition is okayish. However, as you can see the inside of the GG-3 metal lens hood has scrapes to the black coating. 

The glass elements of the lens seem relatively clear and fine. No significant visible scratches to outside of metal lens barrel.

No visible oil on aperture blades.

Made in Japan.

One of my favourite legacy lenses, quite good image quality for its relatively small size. (I tried uploading a sample photo but unfortunately eBay image compression reduced the image quality too much). 

You can see some other people's photos taken with the Zeiss G Sonnar 90mm f2.8 on the flickr group located at https://flic.kr/p/UbdK5x
