GH4 Speedbooster - m43 to m43 to regain the x2 crop?

[TheTrickster]

Using the GH4 in 4K mode, we are loosing some of the WA of the lens due to it using a smaller part of the sensor.

I wondered if anyone has considered an active (so pass through for the connectors) speedbooster type adaptor that gives us back the 2x crop and not the 2.2x.

Using a SpeedBooster puts you back into S35 teritory.

As David mentioned, for non-Micro 4/3 lenses we have speed-boosters that give us a Super35 crop. For Micro 4/3 lenses it's not possible to put anything between the lens and the camera as you would lose infinity focus.

If you want wider angles then use wider lenses. ( the Olympus 7-14mm f/2.8 zoom should be super popular when it arrives next month )
