Firmware 04 für Sony NEX Kameras - if you have one of these cameras, go ahead, download and install. The art filters are at best funny (funny in the Hipstamatik sense), but what really rocks is the focus peak. The edges with the strongest contrast are then optically marked in the image, which enables really trouble-free manual focusing. This might not be important for AF lenses - but for those who, like me, want to use manual lenses via adapter, it's simply brilliant. After installation, I already played around with the Zeiss 50mm 1.4, which works really well. It gets really exciting when I then put the NEX-3 behind my Contax macro equipment.
