I was at the Bullock Texas State History Museum when I saw this exhibit and made an image. I used the GH4 along with the 12-35mm f2.8 lens. The image was shot with the lens wide open. The bottom image is crop of the top image. I was looking for noise. I was unsuccessful.
The camera is charming to shoot with both a voluptuous EVF and a no nonsense shutter sound. I like it all.
