The only things that actually move on a modern smartphone these
days are the silencing switch, the lock button, a volume
rocker, and (if you’re lucky) a dedicated button for Bixby.
So it’s natural that we’re a little curious to see how the
Samsung Galaxy S9’s new dual aperture works. Lucky for us,
teardown of the phone includes a couple of close-up shots
of the aperture in action.
As iFixit points out, a regular camera’s aperture is controlled
by a number of aperture blades, which are designed to keep the
hole which the light goes through (that’s all an aperture is)
roughly circular. The S9, however, does it with just two blades
— because the aperture only has two settings, f/1.5 and f/2.4;
two blades was apparently enough.
Here’s a fancy slider widget, built out of two iFixit photos of
the S9 Plus, so you can have the virtual aperture adjustment
Still not sold on this phone? Check out your local Best Buy.
The Samsung section at the New York store I just visited had a
jumbo-sized aperture demo. I think it was built of cardboard,
but that doesn’t mean it can’t be educational. Adjustable
aperture might not be enough to save Samsung in the phone
camera wars, but it’s certainly an excellent conversation
And, of course, be sure to check out the rest of iFixit’s
teardown. Overall, the S9 doesn’t do great on repairability.
It’s built out of nicely modular components, but the phone is
difficult to take apart without breaking it, and the battery is
difficult to swap. But that aperture, though!
Here’s iFixit’s video teardown of the regular S9:
