Comparing Panasonic FZ330 to G7 in low light (4k video)

Описание: I did this quick test of the Panasonic DMC-Fz330 and the DMC-G7 cameras to see which would give me better results when shooting in low light.

The same light source was used throughout and the aperture was gradually reduced from maximum to minimum. The light level was measured at EV8.1 @400 ISO (which is equal to EV6 @100 ISO). The subject was just over 5m (17 ft) away and cameras were set at maximum zoom.

Videos are recorded in 4k UHD 25fps at a shutter speed of 1/25th sec. Both cameras have a max ISO of 3200 in video mode.

The Fz330 was recorded at maximum zoom of 108mm (equivalent to 648mm) and has an aperture range of f2.8 to f11. The G7 was recorded with a 100-300 lens set at 258mm (equivalent to 625mm) and has an aperture range of f5.4 to f22 at this focal length.

Both cameras reach their maximum ISO at F11, so the G7 was also recorded with an exposure compensation of +3 at f16 and f22 to brighten the images.

Despite having a smaller chip, the advantage of the wider aperture on the Fz330 is evident in the lower ISO achieved at f2.8 and f4. While I could have compared them the same aperture, I think in low light situations it is more likely that you will want to shoot with a wide an aperture as possible.

*both cameras data show a lower than expected ISO for F11, I believe they should have been 3200.

NOTE: The image compressions used by YouTube will reduce the amount of noise visible so the differences may be less noticeable.
