However, I have the feeling that the iPhone 11 Pro might enable me to make nicer photos. So I am playing with the idea to get one. I would probably not even use it as a phone. Just as a camera.
Does that make sense? Or are there pocket cameras that weight as little as the iPhone 11 Pro and make better photos?
The image sensors are tiny compared to good cameras. More photos hitting the sensor means less need for computational imagery.
The battery in a phone is one day only. A camera's battery will outlast that 5-10x, and you can carry a replacement battery.
Having a focus ring, dials to adjust ISO or aperture or shutter speed, means you can capture challenging shots, where with a smartphone, you point and pray. "Pro" adjustments are with finicky on-screen widgets, that you may not even be able to see in bright daylight or from glare.
If you buy a big DSLR, though, realize it's a hassle to drag it around. If it doesn't fit in your pocket easily, you may not bring it with you, and you can't capture a moment when you don't have your camera with you.
X100F, rx100 series, Ricoh G3 or X system Fuji come to mind.
That said, I think a phone can be a great compliment to a camera. I have a camera I use mostly on holidays but have a moment fish eye on my phone for indoor architecture shots. I'm considering the iPhones 120° wide as a replacement for my phone and moment superfish but not my camera. I really enjoy the physical controls for aperture and ev compensation.
Having said that, some Android phones, especially those at iPhone level prices have very good cameras as well. In my experience an Oppo R2 outperforms a Canon EOS-1000D.
My biggest gripe with smartphone cameras is that they are too wide-angle. Digital zoom simply trades pseudo-telephoto capability for resolution.
The Huawei P30 Pro,for example has an astonishing set of cameras on it - and I often use it as a companion to my "proper" camera.
Though for me at least, the biggest thing that keeps me using an actual camera is the tactile nature of the controls.
I think you would struggle to find one as light as iPhone but maybe take a look at models like the Ricoh GR3, any of the Fuji X series cameras (disclaimer, I have an XT3 and an XT10) or if you are feeling spendy, the Leica Q
