Here you have the images of the new 75mm and 12mm Black lenses. Still missing is the image of the 45mm f/1.8 lens. I am not sure yet but the price of the Black lenses should be the same of the Silver version. Note that two of the three Silver primes are yet discounted (at least in USA).
The 17mm f/1.8 sells for $449 at Amazon, Adorama and BHphoto.
The 45mm sells for $349 at Amazon, Adorama and BHphoto.
The 75mm f/1.8 can be found with a $100 discount at [shoplink 38467 ebay]CameraLand (Click here)[/shoplink].
But I think the price of the Black version will be the previous “normal” price.
