Being on the road quite a lot I came across an issue that seems to be common for nikon lenses.

Shooting towards a light source, I don't see anything weird on my camera screen.

coming home, there is a purple blob in the middle of my picture!

it happened with the 12-24 lens and the 50 mm, so the more pricy ones in the range. a bit of google learned me that this problem ocurres more often with these two but nikon denies the problem.

anyone who has good tips on how to get rid of this when post-processing? it has nothing to do with CA, it is clearly always in the middle of the photo.

Quite a few methods you could use in Lightroom or Photoshop, like dropping the purples or selective tools etc. plenty tutorials on YouTube that may help. My knowledge of them are fairly limited.

dropping the purples and magenta's in general doesn't really help, as I already do that in order to reduce CA. Then the stain just turns into some blue-greenish or any other colour it seems to like. selective tools might be an option, i'll read into it.

do any of you encounter it too? isn't there anything we could do towards nikon?

      When I was doing some long exposure earlier today, I came across a problem. My camera started producing these wierd purple blobs and crosses across the picture, I had been doing it for about 10-20 minutes previous without problems until this happened.


      I'm using a Nikon D3100, 18-55 VR Kit Kens, with a Variable ND Filter set to 10.
      Anybody got any suggestions/remedies? Thanks
