I read here that the iPhone XS has a 4:3 sensor which is 5.6mm x 4.2mm. This is similar to the 6.17mm x 4.55mm (1/2.3") sensors in cameras that I have used for close-ups for some years. I am wondering in what way using an iPhone will provide you with capabilities that are fundamentally different from other cameras with similar sized sensors.
The reason I ask is that with a subject of a particular size filling (the same proportion of) the frame, when using equivalent (for example minimum) apertures I get images that look very similar in terms of depth of field and details with cameras with 1/2.3", MFT and APS-C sensors. So it isn't obvious to me what the particular benefit of an iPhone would be.
At 1:3 a subject around 17mm long will fill the frame of an iPhone in landscape orientation. So would that be around the minimum size of subject you envisage photographing or videoing with your iPhone? (Better I suppose to say would that be the minimum size of scene you envisage ...)
All good questions. I'm coming from APS-C size sensors that are a lot larger than what you'd find in a cellphone. The 1/3 life size magnification that I mentioned was just a guess -again I gotta get some experience shooting with a really small sensor.
Depth of field is purely a combination of magnification and aperture -the sensor size doesn't make any difference. If I can fill the frame on my iPhone 11 Pro Max at well below 1/3 life size then the depth of field is gong to be HUGE compared top what I'm use to. This is what I can do at 1x now with an 80D @ F11 and 1x:
