You are bidding on a Carl Zeiss 21mm f/2.8 Biogon, with the dedicated GF-21 finder for Contax G2 or G1 (if green label). If you're considering buying this lens then you're probably aware of its reputation to be one of the best and sharpest wide angle lenses available. This truly is a fantastic bit of glass.
I'm selling because I now use my Contax G2 for portrait shots so wide is not used as much as I'd like, therefore it's better getting used by someone else! But I'll still be sorry for it to leave me.
This is a rare opportunity to buy this lens on auction as you don't see many pop up with both the finder and the lens (the finder can often set you back £150-200 alone). As you can see, I'm including the finder in the auction as well as the official case for both finder and lens, a skylight filter to protect the lens and also a lens cap.
The lens is in fantastic condition and has been very well looked after. No scratches, dust or haze, it is absolutely lovely and you'll be very pleased with its condition.
I'm starting the bidding at 99p, as is the true spirit of eBay! If you have any questions then please don't hesitate to ask as I believe I can answer anything about this. Cheers!
EDIT: Camera not included, obviously!
