GoPro might rule the action camera market, but competitors have been popping up left and right, trying to carve out their share of the market. One of those competitors is YI Technology, a Chinese manufacturer who recently released its 4K Action Camera, designed to compete head to head with GoPro’s HERO 4 Black Edition at half the price.
When put side by side on a spreadsheet, the specs of the two cameras are almost identical in every regard, from the 4K video features to the wireless capabilities. One of the stand-out features for both cameras though is the integrated image-stabilization technology.
To put this flagship feature of two cameras to the test, YouTuber OneLoneDork has created a comparison video to see what camera offers the best stabilization.
Both of these cameras rely on digital-image stabilization. As such, each shoots at its full 4K resolution and relies on those extra pixels to keep things smooth. What you’re left with when all is said and done is a maximum resolution of 1080p.
Throughout the four-minute video, it rather evident that the Yi 4K Action Camera comes out on top, with impressive image quality and superior stabilization capabilities compared to the GoPro Hero 4 Black Edition. As mentioned in the video though, the stabilization capabilities of the Yi 4K Action Camera comes at the cost of less dynamic range to work with in post production.
But let’s be honest. If you’re concerned with color grading your action cam footage in post production, you’ll probably be shooting at 4K and correcting for stabilization in post production anyways.
Considering the Yi 4K Action Camera comes in at only $250, while the GoPro HERO 4 Black Edition is $450, it’s safe to say you’re getting quite the bang for your buck with the Yi 4K.
Fujifilm just gave its most popular instant camera a serious digital upgrade. The Instax Mini Evo 2 now comes with a touchscreen, larger sensor, and a video feature that captures four seconds before each photo. It is set to arrive by the end of November for $289.95.

Full-frame cameras tend to be chunky beasts, but Sigma wants to prove that big imaging doesn't need a big body. Enter the Sigma FP2, the successor to its tiny, boxy fp mirrorless camera. It keeps the same modular design but packs in some serious upgrades, including a 24.5-megapixel partially stacked full-frame sensor, improved autofocus, 6K video recording, and 70GB of built-in storage. Sigma calls it the world's smallest full-frame camera, and while it might be tiny, the same cannot be said for its price tag.

A phone thermal camera is one of those tools you don’t think you need until the first time it saves you from an expensive problem, and the Thermal Master P3 just got easier to try. For Halloween, it’s discounted with the code THERMCAM10, a 10% cut that works out to $107 off the total. It’s also fresh off a win at the 2026 Tom’s Guide AI Awards for best phone thermal camera, which is the kind of third-party nod that separates a serious tool from the cheap clip-on sensors that flood this category.
