4.3mm F/2.5 M12 Camera Lens with Manual Focus

This 4.3mm M12 camera lens is designed for imaging applications using a 1/2.7-inch sensor format. It combines a fixed F/2.5 aperture, manual focus adjustment, and a six-element 4G2P optical construction.

With specified TV distortion below 0.7%, the lens is an option for camera designs where image geometry matters. The M12 × 0.5 threaded mount allows focus adjustment during assembly, with a specified minimum object distance of 0.5 m.

On the reference SC535HAI sensor configuration — 2592 × 1944 pixels with a 2.0 μm pixel size — the specified field of view is 74° diagonal, 62° horizontal, and 49° vertical. Field of view will vary with sensor dimensions and the active image area.

• Low TV Distortion Specified TV distortion below 0.7% helps limit geometric deformation. Applications requiring calibrated measurement should still be evaluated at the intended working distance.
• 4.3mm Focal Length The 4.3mm focal length provides the specified 74° diagonal field of view on the reference sensor configuration.
• Fixed F/2.5 Aperture A fixed aperture simplifies the optical configuration for camera systems that do not require iris adjustment.
• Manual Focus Adjustment Focus can be adjusted during camera assembly to suit the intended working distance. The specified minimum object distance is 0.5 m.
• M12 × 0.5 Threaded Mount The lens uses an M12 thread with a 0.5 mm pitch. Holder dimensions and sensor positioning should be checked before integration.
• 4G2P Optical Construction The optical assembly uses four glass elements and two plastic elements.

• Face Recognition: Face capture for access control.
• QR Code Payment: Code imaging for decoding.
• VR Devices: Visual input for motion tracking.
• High-Speed Tracking: Moving-object image capture.
• Terminal Scanning: Document and barcode imaging.
• Robot Vision: Images for positioning and guidance.
• Security & Smart Home: Indoor and outdoor monitoring.
• AI Training Data Collection: Image capture for AI datasets.
• Medical & Life Science Imaging: Image capture for microscopy and research.

1. 1 Share Your Requirements Tell us your sensor model, target field of view, working distance, aperture requirements, and available installation space. Include your lens holder drawing and IR-filter requirements, if available.
2. 2 Optical and Mechanical Evaluation We review sensor coverage, focal length, distortion requirements, mounting dimensions, and back focal requirements to assess compatibility with your camera design.
3. 3 Confirm the Proposed Configuration Based on the evaluation, we propose a suitable lens configuration or discuss feasible modifications. Specifications, sample costs, minimum order quantity, and lead time are confirmed before proceeding.
4. 4 Sample Preparation and Testing Once the proposal is approved, samples are prepared for evaluation with your sensor and camera assembly. Test image sharpness, field of view, distortion, focus range, and mechanical fit under your intended operating conditions.
5. 5 Final Specification Approval Share your test results so any required adjustments can be reviewed. The final optical specifications, mechanical drawing, filter configuration, and acceptance criteria are confirmed before production.
6. 6 Production and Delivery Production proceeds according to the approved specifications and order requirements. Inspection and delivery arrangements are agreed upon before shipment.

Shenzhen Sinoseen Technology Co., Ltd. was established in June 2016 and specializes in CMOS camera module design, development, manufacturing, and OEM/ODM services.

Its product portfolio includes USB, MIPI, and DVP camera modules, with services extending from development through manufacturing and after-sales support.

For embedded vision projects, Sinoseen works with customers to assess the imaging task alongside mechanical and electrical integration requirements. This helps define a camera configuration that can be evaluated in the intended device before production approval.

Sinoseen's documentation includes quality management records, product compliance documents, software copyrights, and utility model patents. For your camera module project, please request the current documents applicable to the selected model and configuration, including relevant CE, FCC, or RoHS documentation.

• Is this a complete camera module? No. This product page describes a lens. A working camera system also requires a compatible sensor, lens holder, electronics, and image-processing hardware or software.
• Does the lens support autofocus? The specification lists manual focus. Focus is adjusted mechanically during integration; autofocus is not specified.
• Is the aperture adjustable? No. The lens has a fixed F/2.5 aperture, with a specified tolerance of ±10%.
• Will the field of view always be 74°? No. The 74° diagonal field of view is specified for the SC535HAI reference configuration. A different sensor size, crop, or active image area will change the field of view.
