In other words, the noise advantage of FF comes when:

  • There is enough light at base ISO to shoot the desired DOF with a slower shutter speed and not suffer from motion blur and/or camera shake (e.g. 24mm f/8 1/200 ISO 100 on FF vs 12mm f/4 1/800 ISO 100 on mFT).

  • A more shallow DOF is desirable, or, at least, preferable to more noise (e.g. 50mm f/1.4 1/100 ISO 1600 on FF vs 25mm f/1.4 1/100 ISO 1600 on mFT).

There's one more (the most common for me):

  • For the same level of acceptable noise, a shallower DOF is preferable to a slower shutter speed, in order to avoid motion blur (e.g., 50mm f/1.4 1/60 ISO 3200 on FF vs 25mm f/1.4 1/15 ISO 800 on mFT).
