Sorry to hear that; in Bangkok you can buy them of the counter, both Batis and Milvus lines; bit waiting on the Loxia 21.I made the mistake of pre-paying at a dealer in December for the 85mm.. with an ETA of last week...
Who is now telling me that I have about 10 people ahead of me, some waiting since September.
New ETA doesn't sound promising.. easily 4-8 weeks more.
