Voigtländer Ultra Wide Heliar 12mm/5.6 attached to Sony NEX-7 via Novoflex NEX/LEM

The lens mount of the Sony NEX camera system is called E-mount. The E stands for Eighteen, as the flange focal distance of the Sony NEX camera series is exactly eighteen millimeters. Most interchangeable lens systems use a longer flange focal distance and therefore you can adapt nearly every available lens to the E-mount of the Sony NEX camera system.

In this case I used the NEX/LEM adapter from Novoflex to adapt an Voigtländer Ultra Wide Heliar 12mm/5.6 to a Sony NEX-7. On a full frame sensor this setup equals to a focal length of 18mm.

You must be aware that this combination only allows manual control. But the Sony NEX camera system assists in the use of manual lenses if the camera is proper configured:

  1. Make sure you enable the shooting without a lens: Menu → Setup → Release w/o lens → Enable
  2. For the first generation NEX cameras (NEX-5 and NEX-3) make sure you have an actual firmware (≥ version 04) installed. Check this by using Menu → Setup → Version. When you have an older version installed then download the latest version from the Sony support site .
  3. Enable the MF Assist function using Menu → Setup → MF Assist → 2 Sec
    You can choose between No Limit — 2 Sec — 5 Sec.
  4. Enable the Peaking Level using Menu → Setup → Peaking Level → Mid
    You can choose between Low — Mid — High.
  5. Choose your Peaking Color using Menu → Setup → Peaking Color → Red
    You can choose between Yellow — Red — White.

Switch your camera to A- Mode (aperture priority) and use the MF Assist button to get a perfectly sharp picture even when shooting a fast lens wide open.
