XF100 Automatic Gain
 

Hi,

I'm fairly new to the XF100 so I am still getting used to it. Are there any noise benefits to using -6.0dB of gain vs. 0dB?

I ask because I notice that, when set to 'auto' the gain level will not drop itself below 0dB. Is it possible to allow a lower limit below 0dB in the same way that you can set an upper limit on the AGC?

Thanks,

Torsten.

You can use it like an electronic ND filter and it may give a less noisy picture. So yes, when in bright sunlight use it - especially if you want depth of field.

On my XF300, I always have AGC set to Off and the default Gain set to -/- 3 dB to have the least amount of noise in normal conditions. I use the ND filter settings to keep the iris to anywhere in the region below (in a numerical sense) f 6.8 for proper DOF and detail.

In my experience, there is much less noise at -6 db than at 0 db. I have my gain settings at -6, -3, and 0. I always try to shoot at -6.
