Spots on Footage -- Help

Hi All,

I haven't been here in a while but now I'm having a problem with my AF100 and I need help!!

The other day, before shooting, I noticed when I looked through the camera that there was a weird fuzzy round spot. I thought at first it was a dirty lens at first. Cleaned the lens, cleaned the lcd and viewfinder -- no luck. So, I changed the lens to see if it still appeared. It did.

Next I decided to see if one of the ND filters -- that cover the sensor -- were dirty. Cleaned them all. No luck.

Not sure what to do next. I have attached screen shots for you to look at shot at different exposures -- just cause it looks different at different exposures. These are pngs. I also did a 'grab' of a frame showing overexposed range check green and red lines. I did this so you can see that the circle (spot) I have does not seem to be affected by the overexposure indicated in the rest of the frame.

I hope you all can figure it out for me and that the overall judgement is -- your camera is fried . . . .:cry:

please see attachments . . .af100 spot test 2.jpgaf100 spot test 3.jpgaf100 spot test 4.jpgaf100 spot test 5.jpgaf100 spot test 6.jpgaf100 spot test 1.jpg
 
How do you think dust got on the sensor -- the sensor is behind the nd filters? And, how do I get the sensor cleaned? Does it need to be serviced? Finally, the thing that is really weird to me is how perfectly round the white circle is in the overexposed pix I attached that shows the range indicator lines. That sure doesn't look like dust!
 
From an email I got from Panasonic a couple of weeks ago that their service center has moved.

I hope you get this sorted Catherine. I also wanted to comment on how well you tested and showed your "issue". Very professional approach.
 
Thanks for the address and contact info Mark. Just wish I didn't have to go that route and that it's something minor since the camera is no longer under warranty. :(

Have you tried different lenses?

See post #1

Op: try this (at your own risk)... Drop your camera on its base from about an inch high, it might knock the chunk off the sensor. Make sure you have a softer surface like a mousepad or a stack of papers. Or you might try tapping firmly around the lens mount.
 
Dropping the camera? Hmmm. I actually think I'll try it . . . as you describe. I did turn the nd filter knob around really fast while pointing the lens mount down. (Another suggestion above.) If it works, I'll try anything . . . any other ideas out there?
 
same happen to me, it was a spec of dust on the glass in front of the ND wheel and sensor, easily fixed with a cotton bud and a air can - please check that this is not your issue! before sending the camera to a service centre

The sensor and ND filters are sealed behind this glass (at least on my AF-100). There is no way to access the ND filters or sensor on my camera.
 
Aircan is easy. Hold it upright and test blast it first...away from the subject (to clear the nozzle and tube). Then just give it a subtle blast or two at the target.
 
I have often been told not to use canned air -- perhaps there is a specific type that can be used on the glass covering of the sensor?
