This is the year of the first major expensive lenses for the Fuji X and Sony E-mount system:
1) Fuji will announce the new 200mm f/2.0 which is rumored to cost around $6,000 (Fujirumors).
2) Sony’s new 400mm f/2.8 FE will be launched in September (Bhphoto). The price is rumored to be above the magic $10,000 limit.
If you got rich with Bitcoin you might can buy them :)
