If your High Quality Camera is producing blurry images, it's usually related to the lens adapter ring or the focus section of the lens.
Adapter Ring
Some lenses (such as the 6mm lens) require the camera adapter ring to be removed, otherwise the lens will be at an incorrect distance from the sensor and will not function as designed.
If your images are blurry, check your lens spec and or try with/without the adapter ring to see if the image improves.
Lens Focus
You may also need to turn the focus section of any attached lens a number of times to bring the lens into focus. Some users have reported (depending on the lens used) up to 5 turns being required to set the lens properly.
Remember - the HQ Camera needs a lens to function properly. Without a lens, no image will be produced!
