TOMLOV TM4K-AF 4K Autofocus Microscope 52MP

This 8-inch TOMLOV autofocus 4K digital microscope brings high-resolution imaging and hands-free focusing to electronics repair, coin inspection, and micro-soldering tasks. It combines a flexible articulating arm, dual gooseneck lights, and a large screen to simplify inspection work and speed up repetitive tasks.

Key Points

The microscope offers continuous autofocus with a TOF sensor that adapts to movement and varying surface heights, reducing time spent on manual adjustments. For quick task switching, two preset focus buttons let you save and recall focus positions for uneven objects or different work heights. The twin adjustable gooseneck spotlights replace a traditional ring light, allowing a narrow beam for fine detail or a wider wash for broader views, which helps when inspecting reflective coins or populated PCBs. 📸

Positive Aspects

The articulating flex arm rotates and tilts to reach awkward angles, which is especially useful during soldering and component-level inspection. Multiple output options include HDMI and USB, letting you display the live feed on external monitors or capture footage for documentation. The unit also supports a locate function and 4x digital magnification for quick navigation across a workpiece, and eight DIY grid lines help align components or plan soldering points. 🔧

Usage Recommendations

For PCB soldering, set one focus preset for the board surface and the second for taller components to switch quickly between views. When photographing coins or small specimens, adjust one gooseneck to reduce glare while using the other for fill light to preserve color fidelity. The HDMI output allows simultaneous display on external screens for collaborative inspections or teaching demonstrations. Consider that extremely reflective surfaces may still require diffusers or angled lighting to avoid hotspots, according to the manufacturer. 🔦

This device includes easy-to-use controls for image capture and video recording, and the included 64 GB card provides immediate storage without extra purchases. Note that while the system achieves very high digital zoom and detailed stills, effective optical resolution depends on the working distance and lighting setup, so expect best results when using stable mounts and controlled illumination.
