B&H has the new Zeiss 15mm f/2.8 Distagon available for pre-order for Nikon or Canon with an availability date of April 12.
Thank you for ordering through the buttons on my Zeiss gear page, which also shows in-stock status (blue for in stock, red for out of stock).
As I write this, all the Zeiss ZF.2 lenses for Nikon and ZE lenses for Canon were in stock, including the new 25mm f/2 Distagon.
I consider the Zeiss 15mm a must-have lens for anyone looking for an extreme wide angle; it performs so well in so many ways. I have ordered both Nikon and Canon versions, as I will continue to report on it, and of course my coverage has just begun for my Guide to Zeiss ZF / ZE Lenses.
