I noticed that the new iphone 12 has a f/2.0 aperture telephoto lens whereas my existing iphone XS has a f/2.4 aperture telephoto lens. What are the implications of this?

A lower f-stop number means that the aperture is bigger (relative to the focal length), such that it let's in more light. This has several subjective benefits: more light can be used for shorter exposure time or lower ISO (sensor gain) each leading to a sharper image. Also, it creates a shallower depth of field or "more blur" which separates the subject for a more pleasing picture. (This may be irrelevant on sensors as small as on a phone, which counteract shallow depth of field effects.) It may reduce the image quality if the lens of of lower quality, as it is more expensive to build large-aperture lenses.

The magsafe is really cool but for anyone interested in the wallet accessory just be careful with putting NFC chipped cards there. Paying with Apple Pay from your phone could get confusing.

Maybe the wallet has NFC shielding.

Seems like it is. From the apple store:

Lower f-number means that lens captures more light and has less depth-of-field (more blurred background and foreground). For small sensors like in iPhone DoF is huge anyway and planes separation has to be faked in post-processing. In general less f-number is better.

It's the annual incremental improvement, and many will like the smaller form factor too I'm guessing. But the whole 5G hype is lost on me. Specifically, none of the carriers or handset makers are telling me how much the data will cost . Maybe I'm a little price-focused, but that determines for me whether I'm excited about it. If I'm just burning through my existing data limit faster, what's the point? What's the pric…

The whole 5G thing is just complete bullshit. After the tech has flopped pretty much worldwide and Verizon's and AT&T's "5G REMOTE SURGERY" and "RACE TO 5G" marketing bs didn't get consumers interested, they finally decided as a last resort to pay Apple and see if that will be enough to push this technology through.

Yeah it's completely useless lol.

All of this buzz so that a bunch of nerds can do speed tests and post them online.

What's the use? Youtube vids a second faster. Upload stuff to instagram .5 sec faster.

Nobody wants tech to be so intrusive in life anyway.

Why is this considered an exemplary shot? https://www.apple.com/v/iphone-12/a/images/overview/camera/s... (first picture under "Automatic magic")

The pants look artificial, the hands and feet are really dark, you can't see the detail on the trees. Is this just a really hard angle to shoot, against the summer sky?

It's not the start of a massive shift. You'd be surprised what the gaming spending per platform breakdown looks like - phones are a MASSIVE chunk, and growing by far the fastest. I don't have the numbers on me to back this up but maybe someone else can fetch them.

The rule of thumb when it comes to sizing gaming audiences is: - Mobile: Billions - Console: 100s of millions - PC: 10s of millions In other words, a decent mobile game (not Fortnite or LoL, but something like Among Us) can get 100s of millions of users, a good console game can sells 10s of millions of copies and a PC game can sell millions of copies.

>- PC: 10s of millions

According to one source[1], steam alone has 95 million monthly active users. Not every pc gamer has steam running, so actual PC gamers are definitely in excess of 100 million. By comparison, ps plus and xbox live have 103 and 90 million monthly active users respectively. I'd say that PC and console gaming are within the same order of magnitude.

You want the lowest f-stop number possible for telephoto, so you have more available light hitting the sensor. This allows you to get a higher shutter speed. The higher shutter speeds compensate for the exaggerated shake you get from the longer lens.

I suspect you are confusing f-stop (ratio of aperture diameter to focal length) and focal length ("zoom").

Also the f-stop marketing is annoying to me - the f/2.4 aperture on an iPhone lens is probably equivalent to like f/22 on an FF lens for most purposes.

"The iPhone mini fits in the palm of you hand" lol. It's interesting that a reasonably sized phone is now a selling point in itself. In general i like keeping my devices for as long as possible - so when i jumped from the iPhone 6 to the iPhone 10, i was surprised to learn that the phone was hard to use with one hand now, extremely slippery and way, way heavier than my iphone 6. The mini seems like a good size for me…

Phablets also fit in the palms of some people’s hands. There’s a surprisingly wide range of human variation in hand size.

My larger-limbed friends used to complain about how hard it was to operate dinky candy-bar phones with their large fingers. And today, they’re perfectly happy holding and tapping on a Galaxy S20 Ultra, presuming the display has been scaled up.
