Lens for Nac Image Technology Memrecam Hx Video Camera System
Last Updated on October 7, 2026 by Jim C.
The standard lens for nac image technology memrecam hx video camera system models is the F-mount, which allows for compatibility with a wide range of professional Nikon-style optics. You must verify the specific sensor size and mount type on your camera’s data plate, as high-speed systems often require specialized glass to handle light intensity and vibration at high frame rates.

| Item | How much | Why it’s needed | A substitute |
|---|---|---|---|
| F-mount lens | 1 unit | Required for connection | none — don’t swap this |
| Mounting adapter | 1 unit | Corrects flange distance | none — don’t swap this |
| Lens support | 1 unit | Prevents mount stress | Tripod collar mount |
| Cleaning kit | 1 set | Removes dust/smudges | Microfiber cloth only |
| Protective cap | 1 unit | Keeps sensor clean | none — don’t swap this |
Preparation for lens installation
- Power down the camera and remove the battery to prevent electrical shorts.
- Place the camera on a stable, flat surface to avoid accidental drops.
- Remove the body cap and verify the sensor is clean and free of debris.
- If you’re working in high-vibration environments, use a lens support bracket to distribute weight.
- Consult the NAC Image Technology technical specifications to confirm the flange focal distance matches your specific model, as using the wrong mount can permanently damage the sensor alignment.
Attaching the optics
- Align the white index mark on the lens barrel with the matching mark on the camera’s F-mount.
- Insert the lens into the mount gently, ensuring you don’t force the metal ring against the sensor.
- Rotate the lens clockwise until you hear a distinct mechanical click, confirming the locking pin is engaged.
- Check the connection by gently pulling the lens toward you; it shouldn’t move or wiggle in the mount.
- Connect the lens aperture control cable if your specific lens requires manual electronic power from the camera body.
- Set the aperture ring to the “Lock” or highest f-number position if you’re using manual vintage glass.
- Perform a focus test at a low frame rate to ensure the image appears sharp across the frame.
- Tighten the lens support bracket screws if the lens weight exceeds one kilogram to prevent sagging during operation.
Confirming correct alignment
You’ll know the setup is successful when the camera body recognizes the lens aperture range and the image remains sharp across the entire field of view. If the image appears soft in the corners or shows vignetting, the lens may not be fully seated or the image circle of the glass is too small for the sensor. Check the display for a clear, high-contrast image while zooming through the full range. If you see persistent blur, re-seat the lens to ensure it’s perfectly parallel to the sensor plane.
Troubleshooting mounting issues
| What happened | Why | What to do |
|---|---|---|
| Lens won’t lock | Misaligned mount marks | Align marks and retry |
| Image is blurry | Incorrect flange distance | Add a compatible adapter |
| High-speed flicker | Aperture not locked | Set to highest f-number |
| Error code on screen | No electronic handshake | Clean the electrical pins |
| Lens feels loose | Missing support bracket | Install a support rail |
Frequency of maintenance
You should inspect and clean your lens connection points after every high-speed shoot or whenever you change environments. Dust and debris can settle on the mount interface, causing communication errors between the camera and the lens. If you operate the camera in dusty or outdoor conditions, check the seal more often. Always keep the body cap on when the lens is detached to prevent sensor contamination, which is the most common cause of image artifacts.
Frequently asked questions
Can I use non-Nikon lenses?
Yes, you can use other brands if you have a high-quality F-mount adapter. You must ensure the adapter maintains the correct flange distance for your specific sensor, or you’ll lose the ability to focus at infinity.
Is it safe to change lenses during a shoot?
No, you should never change lenses while the camera is powered on or in a dusty environment. Powering down prevents electrical shorts, and a clean environment protects the internal sensor from permanent dust damage.
How long does a lens installation take?
About one minute is standard for a professional setup. If you’re using a heavy cinema-style lens that requires a support rail, allow five minutes to ensure the weight is properly balanced and the mount is secure.
What happens if the lens isn’t locked?
The lens may rotate unexpectedly during high-speed captures, causing the image to lose focus or fall out of the mount entirely. Always pull gently on the lens to confirm the lock pin is fully engaged before recording.
Does the lens aperture matter?
Yes, the aperture setting determines the light intake and depth of field at high frame rates. You must use a lens that can handle the specific light requirements of your frame rate to avoid underexposed or noisy footage.
How do I fix a loose connection?
Tighten the lens support bracket or use a shim if the adapter is slightly thin. Never force the lens to turn further once it clicks, as this can damage the locking pin or the camera mount threads.
Lens nac, in short
Choosing the right glass for your high-speed system requires matching the lens image circle to your sensor format. Always verify the mounting interface on your specific camera model before purchasing or installing equipment to ensure you maintain the structural integrity and image quality required for your high-speed recordings.
