This deal was live 2 days ago with 2 units to ship. Now it has been put on eBay again, with 2 units to ship. To my knowledge Cameraland is a reputable dealer, I don’t know why the have the same exclusive deal live again.
The Zeiss Otus 85mm f/1.4 normally sells for $4,499 (Amazon), authorized Zeiss dealer and eBay seller Cameraland (99.8% positive ratings) has the Zeiss (Canon mount). Not bad! Cameraland says:
We had an in store demo and these were shown and put back in the box. Because of this we won’t sell them as new never opened
Just 2 units available :-) The deal is very tempting but be sure to know all the details.
