Future iPhones may quietly fix one of mobile photography's biggest issues
Referential image of the iPhone 16 Pro Max cameras. | Image credit — PhoneArena A newly filed Apple patent suggests that future iPhones could feature a major upgrade to autofocus technology. Instead of using a single infrared dot projector, like many current models do, Apple is exploring a system that uses two invisible laser beams working together to lock focus more quickly and accurately, even when the subject — or the user — is moving. The patent, labeled US 12335613 B2, explains how this twin-laser system would function. When you raise your phone to take a picture, each laser fires a pulse of light at a slightly different angle. Tiny sensors measure how long it takes for those reflections to return. If both beams agree on the distance, the iPhone locks focus immediately. If not, the system waits and switches to the traditional autofocus method before trying again.

LG introduced it with the LG G3 back in 2014 to improve focus speed in low light. ASUS also included laser modules in its Zenfone lineup, while Huawei and OnePlus used them as part of hybrid systems combining laser, phase detection, and contrast-based methods. Google's earlier Pixel models also featured laser autofocus, though it later shifted toward dual pixel and computational approaches. However, all these systems used a single laser beam, which could be fooled by reflective surfaces like glass or metal. However, Apple's proposed system stands out by using two lasers at different angles to verify distance more accurately. If the two signals disagree, the phone falls back on more traditional focus methods before retrying — something no existing phone camera does. Figure in Apple's laser-based autofocus filing. | Image credit — USPTO This new approach could help reduce blurry photos in many common situations — like snapping a picture of your pet running in the yard or capturing a landscape from inside a moving car or plane. The lasers offer more precise depth judgment, especially when dealing with reflective surfaces like water, metal, or glass. In Apple's filing, a few potential advantages are highlighted: Faster photos: The lens won't need to hunt back and forth to find focus, so you're less likely to miss fleeting moments. Improved accuracy: The system can detect and avoid false reflections, resulting in clearer images through windows, fences, or in low light. Better efficiency: Less focus searching means lower power usage, which could slightly extend battery life over time. It's important to note that, though the patent describes a camera that could function in high-motion environments, Apple has not confirmed whether this system will appear in upcoming iPhones. Like many of Apple's patents, this may or may not become a commercial product. However, the small size and solid-state nature of the components make them a practical fit for future iPhone models or even devices like the Vision Pro. If this feature does ship, Apple could brand it with terms like "instant laser focus" or "dual-beam depth lock." But I think that for users, the benefit will be simple: more dependable sharpness in everyday photos, especially when time and movement are working against you.

Panasonic's S1R II Is a Capable, Affordable, Mirrorless Hybrid Camera
The S1RII features Panasonic's latest phase-detection autofocus, which has much better subject recognition and tracking algorithms. The S1RII can recognize people, animals (dog, cat, bird), cars, motorcycle and bikes, trains, and airplanes. In my testing, Panasonic's subject tracking system is very nearly as good as what you'll find in Nikon, Canon, Sony, and Fujifilm. It wasn't necessarily the best for everything—for example, Nikon stands out as better at tracking birds—but it's an all-around solid autofocus system that doesn't miss much. Photograph: Scott Gilbertson What I did not like is not what it does, but what it can't do—namely, stop tracking a subject when in subject-tracking mode. For example, if I am tracking my dog playing on the beach in the early morning and want to stop for a second and shoot the sunrise, on my Sony and Fujifilm I can tap the screens and switch the focus to the horizon, compose, shoot, and return to tracking the dog. To do that with the S1RII I had to first toggle off the subject tracking. It isn't a huge hassle, nor is it a deal breaker, but it is a little head-scratching. The rest of the time, I found that the S1RII did a good job of tracking everything I asked it to. Oddly though, it has the hardest time with humans. Sometimes in a crowd of people, it would lose the subject, something that doesn't usually happen in my testing of Nikon, Canon, and Sony cameras. While Panasonic's autofocus system is definitely faster and more accurate than previous versions, it's not flawless. I don't find this a deal breaker at all (I still shoot many manual focus lenses), but it might be worth testing with a rental if you shoot a lot of sports or wildlife. Image Quality I've always liked Panasonic's color rendition for its neutrality. It's not warm, it's not cool, it's just about perfectly in the middle. The only place I saw this vary a bit with the S1RII is in skin tones on my kids, who looked a little pinkish in some lighting conditions, but otherwise I did not find any color rendering oddities. Dynamic range is very good. I was able to lift shadows in RAW files 2-3 stops without really even needing to deal with noise.
