Defect on Lens?

So I just got my DVX200 and I'm testing it out and It seems that my lens is defected. There are two green spots that won't go away no matter where I turn my camera! I tried wiping it with a professional lens pen and brush but the spots won't go away. I don't know if its the lens or the actual sensors that are defected but the spots always are at the same exact spot! Anyone here run into this problem? Could it be just a lens flare?

If it is always in the same spot it is not likely a lens flare. I would attempt a black balance, just in case that might clear up the issue.

To black balance the camera, cover the lens, then press and HOLD the white balance button until you see "BB Set OK". If you cover the lens at the spot goes away, that to me indicates an issue with the lens and not with the sensor.

What I see in the examples looks more like an optical defect than anything that a Black balance will cure.

You do not have to cover the lens to black balance the DVX200.
 
If you are shooting under various light conditions and locations, I do not think it would be a lens flare. Are you shooting in manual or auto? Try auto and shoot in as many locations and different light conditions as possible. Show us a short video clip. It does not appear to be a lens defect. Can't tell much from the photo.

The DVX is a complex camera and it could be some setting that is causing it, or even a corruption in the software. This might be a question for Barry Green. If it is something internal on the chip, etc., Barry would know.
 
You have a very bright light in the image you provided.

Try turning off that light, and light the subject from the front with a softer light and see if the green spots go away.

This looks like a lens flare, not a lens defect, to me.

It is not an April Fools joke. Look at the video she posted....lens flare.

She did not post a video. A screen shot is not a video. Plus I told her to shoot under different lighting conditions and in other locations to test the camera. You can read my first post above. I assumed she did this, and stated if it keeps showing up in other lighting conditions and other locations, then it is not lens flare.

I would guess that anyone buying a DVX200 would know what lens flare is. I have a degree in photo journalism and another degree in film and video, but I knew what lens flare was before I went to school. Everyone knows what lens flare is, even people outside the industry. You would think that someone posting the screen clip with a green spot would have a re-occurring problem. If you shot one scene and saw a green dot, would you assume something was wrong with your camera? So maybe she is joking. Maybe not. It is what it is.

I believe that those of us who said it was a possible April fools joke, were being humorous and stated it partly in jest. I think you need to stop taking things so serious and see some humor in situations. Just like your post on your tough shoot. I started my comment on your post, as I did with the comment you quoted above, with LOL - I am sure you know what that means. I am being light and not tediously serious.
 
I said lens flare and asked for a video example. It was definitely lens flare. Thing is Ms. Alba either doesn't realize that shooting directly into a bare light source will definitely flare a wide open lens, or it was a brilliant prank. I hoped it was the latter, because if you're spending $5000 on a video camera you'd think that someone already knows what flare is. To respond to the OP: yes, it's normal.

LOL, I hope it is a prank too. It reminds me of how do you remove the lens hood?
