So a f/1.8 on a 1" sensor would still gather more light than a f/3.5 on an APS-C?

Just trying to get my bearings here. Does this mean the 1" would do better in low light?

Not necessarily. The relative crop factor of a 1-inch sensor in relationship to an APS-C sensor is 1.8x. An f/1.8 aperture on a 1-inch camera would be equivalent to an f/3.24 aperture on APS-C. That's a 1/3-stop difference in comparison with the f/3.5 lens you ask about. Yes, there's a difference but it's arguably insignificant.

In terms of exposure, the APS-C camera could potentially compensate for the 1-stop disadvantage in maximum aperture by using a slower shutter speed. If that's an available option, the APS-C body would gather more light and make images with less noise. If using a slower shutter speed isn't an option. The 1-inch sensor body would have a slight advantage in total light delivered to the sensor.

At this point, we'd need more detail about the photo being made to make a more complete evaluation of the potential of the two cameras.

Thanks. I'm speaking about video actually. Typically I record 24fps, which means the shutter must remain at 1/50. ISO kept as low as possible.

Well, if you're interested in a hybrid video camera, some of the best options include the Canon C100 (if you need an affordable camera with a professional interface, controls and features), the Panasonic Lumix GH5 if you're more interested in a hybrid video/still camera, and options by Canon, Fuji, Nikon and Sony if you're looking for an affordable vlogging camera.
