This is a nice lens! Sigma will announce the new 56mm f/1.4 lens this week. As usual it will be available as native MFT version too. Well this could make up for the fact that Panasonic and Olympus might not announce a new MFT lens at Photokina :)
Note: Image on top and below show the E-mount version. On the very bottom you see the MFT mount version.
