Parts of my image are doubling (Urgent)

Haha...good comeback.

Seriously, I actually did notice it in my tests, now that I was looking for it. But it's in circumstances that normally wouldn't affect me. For example, wouldn't use an ND in low light, and in bright light most of my pans are slow enough that it really doesn't show. That said, it's a little disturbing since I just ordered a 77mm Fader (have a 67mm) and am wondering if more glass will enhance the effect.
 
I thought I had figured out the problem, in that it was my UV filter. I was filming a few weeks ago and with the filter on the overexposed areas would be doubled and when I'd take it off there would be no problem.

However, I was filming again this weekend, and noticed the problem again without the UV filter on. I thought maybe it was my ND filters. I took them off and I still had the problem. I then put on a different lens, 100mm, and noticed the problem again with and without filters on it.

Now that it has happened with two different lenses, 50mm & 100mm (both Nikons), I feel like it may be a problem with my GH1. The thing is, it still hasn't shown up on my 200mm or the kit lens. I thought maybe my Nikon adapter wasn't on correctly or that the lenses were not on the adapter correctly, but removing both and putting them back on did not help.

Anyone have any similar issues or any suggestions to what I could do to solve this problem?
 
I've noticed "ghosting" with certain lenses. I thought it might be caused by the camera being hand held. From what I've read about legacy lenses on M43 cameras, ghosting may be caused when lenses are wide open on bright images, and light is reflected back and forth from the camera sensor to the rear element of the lens. The size, curvature and distance of the rear element affects the degree of 'ghosting', fuzziness or double image.

I rarely shoot with the lens wide open, so I don't know if that's the problem. I've noticed it happened a lot when we'd use a dry/erase board as a slate, the board would get a double image and when people were wearing white shirts, they would also get doubled.

Is there anyway you could send me a link to where you got the information about the ghosting when the lens is wide open, because I've been trying to find some information on google but have not been very successful.
 
Here's a clearer image of what's happening. Look to the right of guys face. There is a doubling of the light that is on the left side of the frame.

I've noticed it even when the lens is not wide open. Are you doing handheld, does ghosting go away when using a tripod or changing shutter speed?

Yikes Over 2 million hits about lens ghosting:

Looks like there is such a thing as a ghost-reducing lens coating!

"While its large diameter, high-precision aspherical and UD elements, optimized lens element positioning, and flare and ghost-reducing lens coating ensure that this lens delivers the top optical performance in its professional class, Canon has added other features photographers have been asking for-"

This website talks about ghosting in legacy lenses for M43 with examples, although not as pronounced as your example.

I've noticed it on both handheld and tripod. I have not tried changing the shutter speed but I am always shooting at the standard shutter speed.

Thanks for the links. So is my best option to sell my 50mm & 100mm lens as they are apparently not completely compatible with my GH1?

This is normal lens flare? http://www.corybraun.com/imagedoublingvideo.htm

Well that's reflections between the lens elements or into UV filter - you've overexposed that one pretty hard, two steps at least, which is why it's so noticeable. Different lenses have different coatings to deal with this effect. Typically cheaper ones do it less well and old lenses can have more reflections since coating methods has progressed steadily since the 70s.

Cory are you still shooting in MJPEG?

All the stuff that I have posted on here is MJPEG, but I have noticed it in AVCHD as well.

Yes, on that video I overexposed it, but on the stuff I was shooting this past weekend I was exposed properly and still noticing it. The 50mm that I noticed it on is the new Nikon 50mm f/1.8. http://www.amazon.com/Nikon-50mm-Nikkor-Digital-Cameras/dp/B00005LEN4
 
Thanks, I'll look into finding one used. I still don't get why though I had no problems when I used this lens with my 35mm adapter. If it is something to do with the coating, I feel like it would have shown up when I used it with the 35mm adapter as well.
