The C2 premise — read before configuring

C2 is the bank where the GFX 100S II makes its strongest claim to being irreplaceable. At f/1.7 on the GF 80mm at medium format sensor size, the quality of optical separation — the transition from focused to unfocused, the way a face exists in tonal space against what surrounds it — is not achievable from any other configuration in this system or most systems at any price. The depth of field at f/1.7 on a close portrait subject is measured in millimetres. A subject who breathes, shifts weight, or turns their head by five degrees moves the iris plane out of the acceptable sharp zone. Every C2 setting exists to address this single fundamental constraint: precise, sustained focus on a moving human eye, at an aperture where the margin for error is smaller than the eye itself.

GF 100-200mm F5.6 note: this is not a C2 portrait-bank lens. Use it only for distant environmental portrait compression, stage-side portraits, or restricted-access situations where the subject is physically beyond the 80mm/45-100mm working envelope. In that case, treat it as a C3/C4-style long-reach choice rather than changing the core C2 doctrine: higher minimum shutter speed, OIS/IBIS ON handheld or monopod, and no expectation of the 80mm's f/1.7 optical transition.
