I'm at awe

well guys , after exactly 2 x months and 16 days of ownership with my beloved Pentax K5 , cancerous spots started appearing on all my images , I first noticed these spots on the 23rd of June ( exactly on the day of world pentax day ) but the numbers and frequency of these spots progressively got worse. It didn't matter what lens I used they are still there.

Ther camera is currently with the store which I purchased it from to send away for repaires , These are not Dust marks .

we've already checked , the surface of the image sensor is spotless clean.

I will keep you posted !! stay tuned , but no more picture taking for me until my camera gets repaired !!! that's what hurst me the most...

I'll be very surprised if it is something other than dust because that is what it looks like.

Keep us posted.

+1, if that is anything else than a dirty sensor, I'll also be very surprised.

Dust can be next to invisible to the eye, I would be shocked if it was anything else. To see sensor dust you would likely need an inspection loupe.

Ditto here. Did they try a cleaning before they sent it off?

Dust

+8 looks like dust, try using a rocket blower

On viewing the full size image I did notice a few dead pixel....

+9 My K-x had two such marks this spring, showed up on all 800+ pics of my trip to new york in post. Quite annoying, but it was the first time I had dust on the sensor in 2 years with a non-WR camera! I attribute this to my anal retentive lens-changing method: always change lenses in a sheltered area, with the camera facing down, using a rocket blower before mounting the new lens.

The two specs in question were barely visible, but they made spots on the image bigger than yours. I had to do the mirror-up sensor cleaning mode and the rocket blower to get them off.

FYI these sort of things only show up when you stop down to a very very small aperture, that's how I test those sensor stains when I first got my K-5(yes the 1st one was stained, but that's the notorious 38xxx batch, got a replacement from the 2nd shipment batch and have been happy ever since)

This image on your stream appears to have been taken 10 minutes before the one above. Did you do a bunch of cleanup in post?
The one above at f22 and this one is at f16.

rawr · 07-09-2012, 07:56 AM

Dust and dirt, not stains.

**Deimos** · 07-09-2012, 07:58 AM

dust, I see a trend here...

SouthernOracle · 07-09-2012, 09:36 AM

I'm confused. Are you talking about the large black spots that look like dust on the lens/sensor or are you talking about the pink and white single pixel spots that look like bad pixels on the sensor? For all you guys screaming DUST you should look at the original size image. There's a pink spot in the top left, one in the bottom left, a white pixel spot on the left edge in the clouds above the horizon, and a black pixel spot just above and to the right of the sun.
