Install / Remove the IR-Cut Filter

The IR-Cut filter blocks infrared light so that your images have normal color and is recommended for use with CS, C-Mount and most other lens types.

  • Take one of the supplied IR-Cut filters out of its sleeve. Handle it by the edges to keep it clean. Slide it into the slot on the side of the filter holder.
  • Push the holder into the socket on the front of the camera so that the exposed dot is up.
  • To remove use the supplied black plastic spudger tool – insert the pointy tip into the notch above the socket and slowly pop it out.
  • The filter can be pushed out from the opposite side for cleaning with the end of a paper clip.

Adding CS & C-Mount Lenses

  • For normal color make sure the IR-Cut filter is installed
  • For C-Mount lenses add the 5mm spacer ring, for CS-Mount lenses remove it
  • Focus the lens as desired using the rear display or an external HDMI monitor
Pro Tip: Most CS & C-Mount lenses perform best between f4 and f8. Shoot with the iris wide open for soft focused backgrounds in your close-ups. Shoot with the iris closed down for sharp far shots.

Using Lens Adapters

If using C-Mount adapters to mount other lens types on your camera, make sure the 5mm C-Mount spacer is attached and the IR-Cut filter is installed.

Adding M12 Lenses

  • Remove the C-Mount ring and IR-cut filter if present
  • Screw the M12 to CS adapter ring onto the camera (Yellow Bag)
  • (Optional) add a layer of Teflon tape to the barrel of the lens
  • Add the small black locking ring to your lens
  • (Optional) add the orange rubber gasket behind the locking ring
  • Screw the lens into the adapter until sharply in focus
  • Tighten the locking ring against the adapter to lock the lens in place
Pro Tip: Get extra M12 adapters so you have one for each of your M12’s. Once you have them set up and locked in place in the adapter ring you can perform quick lens changes on the fly! Extra adapters are available at www.back-bone.ca/shop

Focusing Entaniya 220°, 250° and 280° Lenses

If the 5mm C-Mount ring is on the camera, remove it. Also, remove the IR-Cut filter and holder. Add 4 or 5 of the set screws to the outside of the red mounting ring supplied with your lens. The black mounting ring that comes with the lens is for Hero4 Ribcage mods and is not required. Screw the red mount onto the camera until snug. Add a layer of Teflon tape to the barrel of the lens and thread it into the orange mount. We recommend attaching your camera to a high-res HDMI screen to set your focus. Once the image is perfectly sharp fix the lens in place by tightening the set screws around the perimeter.

TIPS

  • If your M12 lens feels a little loose inside the adapter, try wrapping a layer of Teflon tape around it. That will ensure a snug fit so that the lens is perfectly aligned with the image sensor. Teflon tape is cheap and readily available in the plumbing section of any hardware store.

  • Keep an air puffer and microfiber cleaning cloth in your shooting kit so you can blow debris out of the camera if needed and keep your lenses crystal clean.
  • If you have a 4K TV switch your camera to 4K while focusing for the sharpest image.

Troubleshooting: 

My camera turns off after just a few seconds! Use the side button to power on the camera instead of the top. Quick capture is triggered by default when you hit the top button so it will try and record. If no SD card is found it will simply turn off. Read the included Hero5 manual for more information.
My footage looks pink! You need to install the supplied IR-Cut filter which prevents infra-red light from reaching the sensor. If your footage looks pink this filter is likely missing, or you are using an ‘IR corrected’ M12 lens which is designed for full spectrum & IR imaging. Most M12 lenses have the filter installed on the back but for CS, C-Mount and other lens types you will need to add it for normal use.
My C-Mount lens won’t focus: This usually means that you just need to add the supplied 5mm C-Mount spacer ring to the camera before adding your lens.
Dark spots in footage, especially when iris is closed down: Your image sensor or filter needs to be cleaned. Using an air puffer is usually enough to blow away any small particles that might have gotten on the sensor. A LensPen MiniPro is also a great tool for cleaning the small GoPro sensor. Also verify that there is no dust or debris on the back of the lens.
Images are blurry on one side with M12’s: Likely your lens is not perfectly aligned with the image sensor. Some lenses have looser thread engagement than others which may cause a very slight tilt. Try adding a layer of Teflon tape to the lens barrel before adding it to the adapter ring as outlined in the tips.
When I shoot footage for 360° video, the image circle keeps moving around: When shooting content from circular fisheye lenses for stitching in 360° video software, make sure the image stabilization feature is turned off.

NOTE: We’ve done our best to accommodate the vast majority of M12, CS and C-Mount lenses on the market, however there will be some designs that aren’t compatible. M12 lenses that are extremely short, have odd shaped barrels or short threads may not work. The lenses at www.back-bone.ca have their compatibility clearly marked. When buying M12 lenses elsewhere look for 1/2.3” or 1/2” lenses that have an IR-cut filter built in for normal color. If you want to perform full spectrum or infra-red imaging look for ‘IR-corrected’ lenses. We recommend 1/2”, 1/1.8” or 2/3” C-Mount lenses with high resolution ‘megapixel’ optics.
