A thought:

Perhaps we should think of the phone less as a camera, more of a productivity device.

Have the phone as a mini mobile computer, and your RICOH GR III as your standalone primary camera.

What’s your goal?

My thought:

If your ultimate desire and vision is to maximize your photography, use a “standalone” camera.

No matter how good the new iPhone camera gets, it will always be far weaker and inferior to a “standalone” digital camera.

For example, testing the new iPhone Pro vs RICOH GR III: the GR 3 has at least 10x better image quality, performance, and ergonomics.

Can you make a great photo on a phone?

Tricky to say.

I’d say right now:

It’s possible to shoot a very very good photo, but not a GREAT photo on a phone.

Why not? Physics. No matter how good a phone camera gets, I don’t think it will ever be good in terms of achieving ultimate beautiful and great aesthetics.
