Just reading through some email's that Zeiss sent to their dealers this week.
I thought I would pass along the up-dates from the dealer newsletter....
The Sonnar T 85mm F2 is now in production and deliveries will begin in June.
The Distagon 15mm 2.8 remains on backorder with deliveries expected to resume shortly.
The first deliveries of the Biogon 21mm F4.5 will start in late June, followed by the 18mm F4 in August.
Hope you find this information useful.
