First expected in late June, the dp2 Quattro release was apparently delayed.
According to a trusted US source, the reason for this postponement is that
Sigma wants to either “add a functionality to the camera, or modify something
”. It is also said that the release date announcement was initially
scheduled for late May.
The delay will depend on the nature of said addition/modification, and if it
is a minor tweak, Sigma may not tell about it. Time for some speculation…
大概是要修成双热靴吧
总之就是要延期了
