In professional enterprise surveillance setups, matching the correct flange focal distance—the space between the rear lens element and the camera sensor—is critical to achieving true image clarity. This premium adapter provides the exact 5mm extension required to deploy specialized, legacy, or high-magnification C-mount lenses on modern CS-mount security camera bodies without sacrificing focus calibration or depth of field.\u003c\/p\u003e\n\u003c!-- TOP FEATURE STRIP (4-BOX PILL MATRIX) --\u003e\n\u003cdiv class=\"cg-feature-strip\"\u003e\n\u003cdiv class=\"cg-feature-pill\"\u003e\n\u003cdiv class=\"cg-feature-pill__icon\"\u003e\u003csvg stroke-width=\"1.8\" stroke=\"currentColor\" fill=\"none\" viewbox=\"0 0 24 24\" class=\"cg-icon\"\u003e\n          \u003ccircle r=\"10\" cy=\"12\" cx=\"12\"\u003e\u003c\/circle\u003e\n          \u003cpath d=\"M12 2a15.3 15.3 0 0 1 4 10 15.3 15.3 0 0 1-4 10 15.3 15.3 0 0 1-4-10 15.3 15.3 0 0 1 4-10z\"\u003e\u003c\/path\u003e\n          \u003cpath d=\"M2 12h20\"\u003e\u003c\/path\u003e\n        \u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__text\"\u003e\n\u003cdiv class=\"cg-feature-pill__label\"\u003eConversion Path\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__value\"\u003eC-Lens to CS-Body\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill\"\u003e\n\u003cdiv class=\"cg-feature-pill__icon\"\u003e\u003csvg stroke-width=\"1.8\" stroke=\"currentColor\" fill=\"none\" viewbox=\"0 0 24 24\" class=\"cg-icon\"\u003e\n          \u003cline y2=\"9\" x2=\"20\" y1=\"9\" x1=\"4\"\u003e\u003c\/line\u003e\n          \u003cline y2=\"15\" x2=\"20\" y1=\"15\" x1=\"4\"\u003e\u003c\/line\u003e\n          \u003cline y2=\"21\" x2=\"8\" y1=\"3\" x1=\"10\"\u003e\u003c\/line\u003e\n          \u003cline y2=\"21\" x2=\"14\" y1=\"3\" x1=\"16\"\u003e\u003c\/line\u003e\n        \u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__text\"\u003e\n\u003cdiv class=\"cg-feature-pill__label\"\u003eThread Standard\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__value\"\u003e1\" Dia. x 32 TPI (Unified)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill\"\u003e\n\u003cdiv class=\"cg-feature-pill__icon\"\u003e\u003csvg stroke-width=\"1.8\" stroke=\"currentColor\" fill=\"none\" viewbox=\"0 0 24 24\" class=\"cg-icon\"\u003e\n          \u003crect ry=\"2\" rx=\"2\" height=\"18\" width=\"18\" y=\"3\" x=\"3\"\u003e\u003c\/rect\u003e\n          \u003cline y2=\"21\" x2=\"9\" y1=\"3\" x1=\"9\"\u003e\u003c\/line\u003e\n        \u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__text\"\u003e\n\u003cdiv class=\"cg-feature-pill__label\"\u003eAdapter Thickness\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__value\"\u003e5.0 mm Extension Profile\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill\"\u003e\n\u003cdiv class=\"cg-feature-pill__icon\"\u003e\u003csvg stroke-width=\"1.8\" stroke=\"currentColor\" fill=\"none\" viewbox=\"0 0 24 24\" class=\"cg-icon\"\u003e\n          \u003cpath d=\"M12 22s8-4 8-10V5l-8-3-8 3v7c0 6 8 10 8 10z\"\u003e\u003c\/path\u003e\n        \u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__text\"\u003e\n\u003cdiv class=\"cg-feature-pill__label\"\u003eCompliance Class\u003c\/div\u003e\n\u003cdiv class=\"cg-feature-pill__value\"\u003eNDAA \u0026amp; TAA Certified\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- SECONDARY CONTENT PARAGRAPH --\u003e\n\u003ch2\u003eHeavy-Duty Anodized Alloy Construction for Flawless Mechanical Alignment\u003c\/h2\u003e\n\u003cp\u003eEven microscopic misalignments in a camera's lens train can cause uneven image sharpness, blurry corners, or focusing shifts.

A C-mount lens requires the lens elements to sit 17.526mm away from the image sensor, while a CS-mount camera sensor sits only 12.5mm deep. Screwing a C-mount lens directly onto a CS-mount camera leaves it 5mm too close to the sensor, making it impossible to focus the lens. This 5mm ring provides the exact extension needed to correct the focal plane.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cg-faq-item\"\u003e\n\u003cstrong\u003eCan I use this adapter ring to mount a CS-mount lens onto a C-mount camera body?\u003c\/strong\u003e\n\u003cp\u003eNo, you cannot. A CS-mount lens must be positioned closer to the sensor (12.5mm) than a C-mount camera body allows (17.526mm). Because a C-mount camera body is naturally too deep, a CS-mount lens would need to be recessed inside the camera body to focus, which cannot be corrected by an external adapter ring.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cg-faq-item\"\u003e\n\u003cstrong\u003eWill using this adapter ring reduce light transmission or degrade video resolution?\u003c\/strong\u003e\n\u003cp\u003eNot at all.
