now what??

Like the second shot btw! 👍

thanks

like pollen?? it can't be dust on the sensor I got that also but it looks different

another one:

it appears to be on the same spot on every images, never seen it before only new is the lens

edit…

looks like it comes from the inside of the lens ;(

In the sea view, some spots have dark centers so not a simple Airy function:

THIS is peeping:

histogram widened with Levels - smoothed 1px Gaussian

Effect seems optical to me and looks a bit like an Airy diffusion pattern pixelated by the sensor:

As to the location of the bright point sources, your guess is as good as mine ...

Gorgeous,simply gorgeous..

Commenting on the prettiness of the Airy disk means that the above technical comment is sadly wasted.

Maybe oil from the shutter. To the OP - was the camera left in the heat lately?

it may be

How about shooting something white out-of-focus at f/22 and +1.5 EC with the dust-cover removed then posting the result at 100% here in PNG format?

When you attach lens to camera do not twist lens to fully engage lock in the mount

yes,I follow and then?

make photo in locked and unlocked position if spots move = lens if not sensor or ir cutoff filter

Good capture.

Yep, they're all over the sensor - apply unsharp mask sharpening to see them.

Top left of image is bottom right of sensor I believe ...

This looks suspiciously like the sensor corrosion that Leica had with the M9.

Some good images here:

Sharpened up in FastStone Viewer

... although the SD9 also uses an "ICF" over the sensor front face, I am inclined toward @left eye's "droplets" opinion.

Perhaps oil droplets from the shutter?
Would suggest to have the sensor cleaned professionally in a camera store.

Not familar with your camera.  I have owned Nikon, Canon, and Sony.

Your droplets are definitely smaller than typical dust.  Because most dust spot on images can be seen without pixel peeping at smaller aperture.

You can see something on the sensor surface.  So something is there.  I would just do sensor wet clean.  Do it yourself or at a shop.  If is dust or oil, then wet clean can remove it.  If it is corrosion, then SOL.

ole,

Do the spots show up on all images or only in certain situations

Are they visible at  say f4  or at f16 or f22

Maybe condensation on the sensor surface from bringing the camera into a heated house out of low outdoor temperatures has left some residue on the sensor.

Have you wet cleaned the sensor recently, if not wet clean it and check for spots then.

Some are suggesting sensor corrosion but there is no evidence of such corrosion in any Foveon sensors to my knowlege.

I checked my old SD9 from 2002 and my old SD10 & neither of show anything similar to your spots.

S

Looks like stuck pixels to me. Have you looked at the raw data? Joe

thanks but Wet clean doesn't help either

Ouch, not good.

When you took the f/22 PNG that you posted, was the dust-cover removed (just checking)? Not that those spots that are only a few pixels diameter should show if they are on the removable dust-cover.

Can the SD9 take shots with both the dust-cover and the lens removed? I would check if it can but my cameras are in a box somewhere. That would tell us if that the stuff is positively on the sensor's cover glass/filter - or (horror) under that on the surface of the sensor itself **.

Don't give up - it ain't over until the fat lady sings ...
