LG Innotek is ready to put true optical zoom lenses in the next wave of flagship phones
LG’s smartphone-making days may be over, but LG Innotek — a major supplier of mobile camera modules — is alive and well. It’s introducing a new telephoto zoom camera module at CES 2023, offering true, continuous optical zoom. The company is partnering with Qualcomm to fast-track adoption of its new tech alongside the Snapdragon 8 Gen 2 in upcoming flagship Android phones.
While most other long smartphone cameras use image-quality-degrading digital zoom to reach beyond their native focal length, LG’s design uses moving lenses — much like a traditional DSLR camera lens — which preserves image detail. This camera module also uses a folded-optic design, also referred to as a periscope lens, keeping the overall size down. The result is a lens…

LG teases a smaller smartphone camera module with true optical telephoto zoom
LG may not make smartphones anymore, but it’s still building components for them. The company’s LG Innotek arm just unveiled a periscope-style true optical zoom camera module with a 4-9 times telephoto range. That would allow smartphone cameras to retain full image quality through the entire zoom range, while potentially reducing the size and number of modules required.
Samsung developed a similar camera module, also known as a “folded” lens, with a four times zoom first used in the Galaxy S20 Ultra smartphone. LG Innotek provided a previous version of its zoom module to Sony for the Xperia 1 IV smartphone.
Most smartphone cameras use hybrid zoom setups that combine digital zoom and multiple camera modules. Certain zoom ranges (typically 2x, 3x, 10x, etc.) use individual cameras, with a digital zoom to fill in between those (2.5x, 4.5x, etc.). As a result, sensor resolution and thus detail can be considerably reduced.
LG’s “Optical Zoom Camera,” however, contains a zoom actuator with movable components, similar to what you’d seen on a zoom lens in a mirrorless or DSLR camera. It operates quickly and precisely down to the micrometer, according to LG, while saving battery life. It also has a built-in optical image stabilizer to reduce blur, something that can be a problem for telephoto lenses that magnify hand movements. (iFixit shows exactly how such modules work here.)
With the module installed, a sensor would retain full resolution through the entire 4-9x zoom range, providing more detail on telephoto shots. LG also pared down the module’s thickness to reduce the size of the camera bump.
The company partnered with Qualcomm to integrate the tech in the new Snapdragon 8 Gen 2 Mobile Platform. “It will enhance the image tuning custom for the optics, which includes Auto-Focus, Auto-Exposure, Auto-White Balance, lens shading correction and much more. Users will be able to focus quickly. And the photos and videos will have stunning image quality,” LG wrote.
The new module will appear in smartphones announced at CES 2023 starting January 3rd. LG didn’t reveal any brands or models, but there are a number of smartphones coming soon with the Snapdragon 8 Gen 2 chipset that could potentially use it. Those include the OnePlus 11 series, Xiaomi 13, Motorola X40 and Oppo Find X. Apple is also a large customer of LG Innotek and could use the zoom module in next year’s iPhone 15 series, according to previous reports.

Logitech’s new G502 X gaming mice have clicky optical buttons
Logitech has three new gaming mice, and the wireless ones finally have USB-C up front. That’s right, Micro USB’s reign of terror continues to be on the decline as Logitech’s new G502 X series gaming mice come to succeed the company’s popular G502 line.
The three mice — G502 X, G502 X Lightspeed, and G502 X Plus — also now include hybrid optical-mechanical buttons for greater responsiveness as well as a more precise 25,600 dpi “Hero 25K” sensor. They’ll have an overall lighter weight and come in both black and white.
While the mice sport the company’s new “Lightforce” hybrid optical-mechanical switches that are designed to utilize the speed of optical technology, they also include the clicking satisfaction of a traditional mouse button….

The optical illusion doesn’t just test your eyesight but also your patience as they ask you to find it in 36 seconds or less.
If you take longer than this, we can assume that either your mind is somewhere else today or maybe you just don’t like frogs.
The image depicts a peaceful pond covered in lotus flowers, with some blooming and others about to blossom.
It also shows fallen brown leaves just to make spotting the frog that little bit harder.
