Later, you can use continuous for moving subjects.

Six, stabilisation. Leave steady shot on.

Seven, JPEG style standard.

Ignore all the vivid portrait options if you're shooting wall.

Eight, a good comparison test.

Since you have Canon EOS M plus 22mm f2, Sony RX100 IV, iPhone 16 Pro,

I'd compare all three fairly scientifically.

Test one, landscape.

Go somewhere with trees, sky, brick buildings, shadows, distant detail.

Take exactly the same composition.

Compare detail, dynamic range, colours.

Now test two, indoor.

Indoor, your living room.

No flash, photograph, books, TV, furniture, lamps.

This shows autofocus, low light performance, white balance.

Test three, portrait or scanner or someone willing to stand by a window.

Compare skin tones, eye sharpness, background blur.

Test four, macro coins, flowers, coffee mug.

Focus close and compare.

Test five, street lights, cars, buildings.

The RX100 IV should comfortably outperform the iPhone once you process the raw files.

Number nine, editing.

I would shoot raw on all three cameras, then edit them all in the same software.

Don't compare the iPhone's processed JPEG to the Sony's.
