I took a number of shots today of flowers, gardens, etc. These two photos were in the middle of the bunch, and showed what appears to be a very dirty lens/filter. However, no other photos (out of about 60 photos)showed any dirt or smudge, and there were other shots similarly composed to these. When I got home and looked at them, I checked my filters and lens and indeed they needed cleaning, but certainly not to the extent that these photos showed. I couldn't pick up any clues through exif data.

Any suggestions or observations?

Also, about ten of them appeared quite washed out in their color. Could it be white balance problems? Thanking you for suggestions in advance.

First one...

Odd, the specs appear to be in focus as well

The specs appear to be dust settled on the lens. There seems to be quite a lot of dust all over the frame. Clean the lens for what it is worth and try again. If yours is a DSLR, this could also be due to dust that might have settled on the CCDwhile changing lenses. In that case, have the CCD cleaned. If that also doesn't work, it is best to give itfor service.

Looks like the camera focuses on the dirt on the lens. You would not see this if it focuses on the subject itself. It's the same with your eyeglasses. You would not notice the dirt if your wearing them. Just try to clean your lens.

Are you by any chance using the Stock adapter on an FZ20?? No exif so I can't tell for sure (if it's an FZ20)..

By the way I have a question:

we know that stock adapter may cause reflections and -with dirty filter as in this case, it is easier that it focuses on the lens dirt, for it is more distant...

But optically speaking there should also be a difference in magnification between a 6T used 2 cm closer or farerfrom the outer FZ lens.

Am I right in saying that a 6T mounted on a standard FZ 20 (longer) hood (via 72-62mm step down ring) has longer working distance and thus also less magnification than one mounted on a shorter Phayee or Pemaraal ?

It seems that I was about 35cm from the subject when I achieved focus using the former configuration yesterday...

Yes, it's an FZ20, no, its not a stock adapter. I have the Phayee adapter, and have not had any problems prior to this, or anything like this before

Got to agree with the others - looks like dust on the lens and that the Fz's focused on them.
