Description
Introducing our revolutionary 70mm F1.6 2MP M12 telephoto pinhole lens, a pioneering breakthrough in long-distance covert surveillance and discrete visual capturing. Tailored with a massive 1/2″ image format and an ultra-narrow 5° Horizontal Field of View (H.F.O.V.), this unique telephoto board lens features a micro-cone tip that lets it remain completely invisible behind panels. While traditional pinholes are limited to short distances, this fixed focal lens can pinpoint targets from far away. Empowered by a super-bright F1.6 large aperture, it captures exceptional 1080P resolution in dim settings, setting a new benchmark for hidden intelligence systems.
Product Highlights
-
- Long-Distance Covert Surveillance: Combines a massive 70mm fixed focal length with a mini-cone pinhole front, enabling the camera to hide behind a tiny slot while capturing distant subjects with precision.
- Ultra-Narrow 5° Target Lock: Concentrates its full 2MP pixel density into an exact 5-degree field of view, ideal for isolating far-off subjects like license plates or facial features without distortion.
- Large 1/2″ Sensor Optimization: Engineered to cover large 1/2-inch image sensors, maximizing light capture, enhancing dynamic range, and eliminating dark corners or edge vignetting.
- Super-Bright F1.6 Aperture: Defies the common flaw of dark telephoto lenses by offering a high-light-throughput F1.6 iris, maintaining high shutter speeds and low digital noise during night operations.

Applications & Device Compatibility
Core Application Scenarios
This specialized 70mm M12 pinhole lens is custom-built for high-end intelligence systems, hidden toll gate enforcement, and remote industrial lens applications. Its laser-focused 5-degree field of view allows it to act as an undercover long-range tracker, perfectly suited for multi-lane automated number plate recognition (ANPR) and remote biometric checkpoints where the camera must remain hidden inside a generic enclosure or wall recess. In precision manufacturing and machine vision lens tasks, its unique combination of a 70mm focal length and an incredibly short 0.2m minimum object distance (M.O.D.) allows automated robotic arms to inspect delicate components or read tiny markings through micro-holes from a safe distance, shielding the optics from extreme heat or debris.
Compatible Device List
-
- Universally compatible with premium 1/2-inch, 1/2.7-inch, and 1/2.8-inch CMOS image sensors (such as Sony STARVIS IMX lines and OmniVision sensors).
- Seamlessly fits into heavy-duty M12 hidden tracking enclosures, outdoor long-range speed domes, and undercover perimeter security pods.
- Highly adaptable for specialized industrial visual inspection tools, laser alignment machinery, and discrete drone/UAV aerial camera gimbals.
- Supports tailored day/night multi-band filter assemblies (650nm / 850nm / 940nm) to withstand harsh traffic strobes or discrete dark infrared tracking.

Frequently Asked Questions
Q: How does a 70mm telephoto lens function as a pinhole lens?
A: Unlike standard wide-angle pinholes, this model is a specialized telephoto pinhole lens. It is engineered with a narrow, micro-tapered tip that can be placed directly behind a tiny physical slot, while its 70mm internal optical layout acts like a high-power telescope to look deep into the distance.

Q: Will this 70mm lens cause vignetting or dark corners on a 1/2-inch sensor?
A: Not at all. This lens is fully optimized for the 1/2″ image format. It creates a large, high-resolution optical circle that covers the entire sensor plane, delivering crisp details from the absolute center to the very corners.

Q: Can this 70mm pinhole lens be used for close-up macro imaging?
A: Surprisingly, yes. Despite its massive 70mm focal length, it features an ultra-short M.O.D. of 0.2 meters. This allows you to position the hidden camera just 20cm away from an object and achieve a highly magnified, zero-distortion macro view.

Q: Does this lens require a special holder due to its 72.3mm length?
A: It fits standard M12x0.5 thread pitches. However, because the physical lens barrel is longer than standard pinholes, we highly recommend using a reinforced, deep-threaded M12 metal mount to ensure structural stability and eliminate vibration.

Q: Is the iris adjustable for changing outdoor light conditions?
A: This model is designed with a Fixed F1.6 Iris to maximize light throughput and maintain high shutter speeds for fast-moving targets. For fluctuating outdoor environments, exposure control is typically managed via the camera sensor’s electronic shutter or software gain adjustments.
