these lenses should come stock on the HDZ 90 cam, they're better in every way compared to the standard lens.

I crashed one of my 3in HD Zero builds and cracked the lens. This is the same lens that comes with the Runcam Nano HD camera and was an easy swap. It's just a pain getting the focus just right, but once that's done, it's good as new!

It’s great, no fish eye like on the lens that comes with the nano.

Completely worth it to upgrade the RunCam Nano HDZero camera. Allows for better FOV and clearer image.

Removed the original runcam lens and installed the new lens and you can definitely see a difference in the image, seems clearer. I do get a little bit of color disturion if the sunlight hits it just right. All in all and approvement.
