Capturing high-speed movement requires more than just a fast shutter. It demands glass capable of keeping up with the action. Forget the "fisheye" look that bends horizons and warps reality. The new standard for professional-grade action capture is here.

Meet the JSD3840.

This isn't your average lens found in off-the-shelf consumer gadgets. This is an industrial-strength optical core designed for the next generation of professional action cameras, drone mapping systems, and high-end sports analysis gear.

Here is how the JSD3840 changes the game.

1. The "Zero-Bend" Horizon

Wide-angle shots usually come with a heavy price: distortion. Curled edges destroy the immersion of a pro skydive or a tactical training review.

The JSD3840 breaks this rule. With a broad 100° Field of View (FOV), it captures the whole scene. The magic lies in the Distortion <0.4%. Straight lines stay straight. Buildings don't bow. Horizons remain flat. You get the immersive width of an action cam with the rectilinearity of

a prime cinema lens.

2. 20MP Clarity Meets Big Sensors

Blurry pixels ruin fast footage. This lens resolves a massive 20 Megapixels, ensuring every droplet of water, grain of dirt, or rapid movement is razor-sharp.

It pairs perfectly with a 1/1.8" Image Circle. Larger sensors mean better performance. Whether facing blinding mid-day sun or the shadows of a canyon, the optical design feeds the sensor pure, high-quality light.

3. Deep Focus, Perfect Size

Action doesn't wait for focus pulling. The F/NO 4.0 aperture ensures a deep depth of field. From the mud on the lens to the mountain in the distance, everything stays in focus.

Engineers love the form factor. The industry-standard M12 Thread makes integration easy. The TTL (Total Track Length) is just 15.8mm. It is compact. It creates room for bigger batteries or better heat dissipation in your device housing.

4. Built for the Pros

This lens serves a specific master: Performance.

Consumer cameras prioritize cheap mass production. The JSD3840 prioritizes optical perfection for specialized equipment. Think industrial drones inspecting wind turbines, body-worn cameras for tactical teams, or broadcast-level sports rigs.
