35mm equivalent for Micro 4/3
Posted 11 September 2015 - 03:34 PM
1.37= 22mm x 16mm
1.85= 21.95mm x 18.6mm
Gh3 sensor= 17.3mm x 13mm
Are these figures right? What focal length should I be looking for?

4:3 is a different aspect ratio than 16:9, you could only scale it to a smaller or larger 4:3 size. I mean, you could scale it to 16:9 by only rescaling one dimension, horizontal or vertical, but then you'd have a stretched image.
The only case in which it would make sense would be if you used a 1.3X anamorphic lens to squeeze a 16x9 image to fill a 4:3 sensor.
Also, if you used a 2X anamorphic lens, then you could use more of the 4:3 sensor to get a 2.40 : 1 image.
But I think this is all moot since I don't believe the GH3 does 4:3 for video, unless it does it for standard def. HD is always a 16:9 format.
The 4K GH4 does now have a function to record more of the height of the sensor (3828 x 2496, which is 4:3), mainly for people who want to shoot anamorphic photography:
