Realtime variable aperture demo on an actually massive sensor. Shoutout to the Sigma Cine lens I've been using for almost a decade. Full video:

Isn’t this we can do with more brightness setting🔆 also?

Canada on your T-shirt. Love it❤️ 🇨🇦💪

Could you show the difference on iPhone using a mobile tele lens?

"Who needs a small sensor when you can have a big personality? Congrats on crushing this demo, MKBHD!" 🤩📸

Key detail reviews are missing. iPhone lenses prior to 18 pro have always been locked at max aperture. The variable aperture on iPhone 18 Pro allows letting in LESS light at a given shutter speed/ISO — not more. Yes, the 18 pro has a faster (larger aperture lens) but that is not a function of the variable aperture lens. This is a separate lens upgrade. Stopping the variable aperture on 18 pro down, will offer slightly better near to far (DOF) range of focus, but more noticeably, will allow slower shutter speeds in brighter situations.

crazy to think youve been using that sigma lens for a decade bro time flies

They’re really good the money I spent on them was worth to be honest

No matter how cell phone cameras get, they are not real cameras.

this is such a good demo of why aperture isnt just "brightness" watching the depth of field change in real time makes it instantly obvious

The aperture changing in real time on a sensor that size is seriously impressive. The Sigma lens longevity is a great detail too.

Sigma's Aizu Prime Line being T1.3 across the range makes this a very Sigma demo.

check how it works:

Nice demo!

Sigma lenses are crazy sharp, this shot is an example

I like the less light part

Which sigma lens bro ? 18 -35 🤔
