    So I've noticed that in some shots, there are blurry parts, and even though I have cleaned off the lens, I think it is still partially scratched or blurry somehow (I'm referring to the stock lens that comes with the P3). I have several ND filters now, but if you're shooting later in the day, the ND filters are too dark, and the regular lens is necessary.

    Where is the best place to buy a replacement lens? I don't care if it doesn't come from DJI. I just want something that is threaded to fit and basically the same as what DJI gives you. I have found a few that I think will work on eBay, but it's hard to know if they're exactly what I'm looking for. None of them say they are threaded, but I assume they are.

    Also, would a Polarizer filter be a bad idea, or are they going to still be too dark for lower light situations? Something like this maybe??

    The official DJI one is MUCH too expensive. I think one of the filters I posted above should work, but I would like to know if anyone has any knowledge of their quality and could speak to whether or not they will be on par with DJI official lens.

    Really, I think I could fix my problem with just the lens plastic itself (not the screw on part or the o ring). Can just the lens be purchased without the rest?

    The lens is glass.

    A pol-filter, as a general rule, attenuates the light with about two stops.

    I think it's not just plain glass. There is some UV treatments done to it.

    Fair enough.

    Let me clarify my question. I'm looking to buy JUST the lens crystal by itself (without the frame that screws onto the camera), OR to buy a complete frame and crystal if it will screw onto the camera. I think the ones I posted above are just slip-on and do not actually screw on and replace the built in lens. (And I'd like to do this for $25 or less if possible)

    There is always a proper way, and a cheap way. Ya just gotta choose.

    That may be, but I refuse to believe that a proper replacement for the lens should cost $40. That's ridiculous, and it shouldn't be this hard to find a lens that is just as good or better than what the Phantom comes with.

    Check the iHot.... ones. Looks like they are all the same style, and are just lined with foam for a press-on fit. No idea if that goes over the stock UV filter frame or slips over the threads.

    First .. what you are talking about is not the lens at all. The lens is a complex array of 9 individual glass elements.
    You are talking about the UV filter that is in front of the lens. It's a flat glass window to protect the lens.
    If your filter was scratched or blurry you should be able to see this.

    You have to wonder why the problem is noticed in some photos.
    If there was a fault that needs replacement, it would show in all photos and in the same part of all photos.
    Perhaps you should look more at the problem photos to determine the cause of the blurriness.
    Motion at slow shutter speeds is the first suspect.

    You are correct in that it is the UV filter I want to replace. I'm pretty sure it's the reason I'm seeing the blurriness in some shots, but I guess it could be other reasons.

    Can you post a picture with the EXIF info intact? Mught help diagnose the blur you are seeing

    If the uv-filter is to blame you will see the blurriness in all your shots. Not in some.

    I broke my glass lens by putting on a sun lens hood. I accidentally pushed the hood down too far, and tried pulling it up for alignment. It was stuck so I reached inside the hood to pull it up but I didn't realize my thumb was on the lens for leverage while pulling the hood into alignment, and the lens easily cracked. I ordered a new lens plus threaded screw on ring, but in the meantime-I improvised a temporary glass lens while waiting for lens replacement to arrived by mail.

    I had a broken mini-mag (like) flashlight, and I took out the clear lens. It was slightly undersized, and then I remembered I had two cheap workplace watches sitting in my dresser for years. I opened one up, took out the inner mechanism, and popped out the glass lens, it fit perfectly (and it was thinner than the flashlight glass lens), took out the rubber gasket from my P3 lens cap, popped it in, and replaced o-ring gasket, screwed it back onto my P3.
