iPhone 18 Pro: Using the New Variable Aperture Lens

Useful takeaways from this story.

The problem with this approach is that the longer the shutter stays open or Night Mode is engaged, the more likely that the imagery will be blurry.

Like the iPhone 17 Pro models, the new iPhone 18 Pro and iPhone 18 Pro Max have three rear cameras вЂ" a 48MP Fusion Main lens, an 8x48MP Telephoto lens, and a 48MP Ultra Wide lens.

The useful part

Like the iPhone 17 Pro models, the new iPhone 18 Pro and iPhone 18 Pro Max have three rear cameras вЂ" a 48MP Fusion Main lens, an 8x48MP Telephoto lens, and a 48MP Ultra Wide lens. They also share the same focal lengths and resolutions as their predecessors. The big upgrade this year though is the new variable aperture on the Main camera.

How it works

Aperture is what controls how much light enters the lens and hits the sensor.
If too little light hits that sensor, images tend to be blurry and/or grainy.
To compensate, the shutter has to stay open longer, or it has to turn on Night Mode.
The problem with this approach is that the longer the shutter stays open or Night Mode is engaged, the more likely that the imagery will be blurry.
The iPhone 18 Pro models can do this automatically, or you can take over the process manually for more stylistic control.

What to take from it

As mentioned, you can leave the iPhone 18 Pro to do its thing with the new variable aperture, or you can take control of it manually.

Details worth keeping

Even still photos can lack sharpness and definition.
