Send us your Hero 4/3+/3 camera and we'll take out the stock lens+mount for you (even if it's cracked and damaged!) and replace it with a glued together matching genuine original Hero 4/3+/3 lens+mount. The camera will be focused exactly like you received the camera when it was brand new. No need to buy the lens+mount item as this item's price includes the part + labor.
Please send us tracking number once you ship it to our office:
