SENSOR
I scratched the Sensor (I presume the sensor cover actually as there is some sort of protection there) on my K10D while cleaning it and the quote was around £200. As it doesn't show up in any great detail until around f11 I haven't bothered getting it replaced.

SENSOR
It is possible that the sensor is just marked rather than scratched. Try cleaning it thoroughly. With a K10D, it will be more economcal to replace the whole camera (with a used one) than the sensor.

SENSOR
It is very unlikely that the sensor will be damaged. A filter, which is in front of the sensor, may be damaged but it is certainly not a user replaceable part. Your camera will need to go to a qualified repair centre to have it fixed. Have you tried wet cleaning products like Eclipse/Eclips...

SENSOR
I still think it's likely to be a mark rather than a scratch. You should try cleaning it again. If a replacement camera is needed, hopefully you will eventually find an eBay seller prepared to ship to Yemen.

SENSOR
Just to be clear, is it definitely the sensor which is scratched rather than the focussing screen? It is much easier to replace the focussing screen.

Macro Tubes
I can't get my head round this, because are are totally altering the optical relationship between the lens and the sensor. You beat me to the post Barrie:D, no my auto tubes set the focal length of the lens regardless of the number of tubes fitted. auto as in auto focus or auto as in "PKA". If it's ...

Macro Tubes
I can't get my head round this, because are are totally altering the optical relationship between the lens and the sensor. A 50mm lens is a 50mm lens no matter how far away you hold it from the sensor. The focal length doesn't change just because you're using it for macro work... :wink:

Macro Tubes
Yep focal length stays the same but you alter the focus distance. If it's auto focus then would the camera not just detect the lens without knowing whats going on in between, as happens with auto focus teleconverters? Don't know about the TC but there is a "chip" in the lens with his data and tha...

HOLIDAY CAMERA SET UP
The kit lens or it's equivalent will be fine. It is a great walkabout and also good for landscapes, and close-ups. Not as wide as some would like or suggest, but really it is good. Maybe a tele-zoom too - great for compressing landscapes and giving a more graphic effect. A tripod is useful, bu...

Kx Can not turn on
There may certainly be grease/oil on the terminals as a protector and cleaning as mentioned above is a good idea but, there may also be some oxidation. In the 'old' days when what should have been perfectly good batteries didn't work we used to use the eraser from a pencil (the pink ones)to burnish ...

Aperture issue with Pentax FA 80-320
I recently picked this lens up with a bunch of other gear and was going to E-bay it but it appears to have a problem with the camera body unable too controll the aperture, all I get is F.... in the top LCD screen. The lens autofocuses and locks on with focus confirmation but aperture control can...

Horizontal Lines on some photos
Hi, I have a K10D and I have started getting horizontal lines on some of my photos. It looks like it could be bad sensor recording? It does not appear in all my photos and is not in the same place each time. I have tried different SD cards so I know it is not the cards. I have checked my sensor and...

Horizontal Lines on some photos
Could indeed be a bad sensor. Personally, I would replace the camera if the fault appears frequently. It wouldn't be cheap to repair even if it was possible to repair.

Dark corner using a cpl
Wrote some things down before seeing the photos, but that's quite strange. Could it be that it only shows up with photos with a small aperture (high f-number) if so then I've an idea what it might be. :) Probably some dirt on the sensor or on the filter but the later is less likely.

Dark corner using a cpl
It's normal for an object that is causing slight vignetting to disappear as you zoom in. Just try obscuring the corner of the frame with your finger near to the lens, then zoom in. What confuses me is that only one corner is affected in Adrian's examples. But perhaps the sensor is not quite align...

Dark corner using a cpl
I'm quite sure that it is the filter that is in shot since it disappears as you zoom in. Stefan is right in suggesting that it will be more pronounced at small apertures. TBH it is hardly notiecable and easily sorted in PP. But strange it's only the top left corner, if it was the filter I would expe...

Dark corner using a cpl
Thanks for all your replies and advice, greatly appreciated. I imagine that if this were a dust problem then all images would be affected (been there as well); touch wood, as far as I can see at present the sensor seems clean. What I can now also add is that images taken without the cpl are cl...

tamron 70-300 and polarising filter
At least that's the basics behind it Glover, if a Tammy user concur with your findings then that's most probably the cause and not the lens or the AF sensor.
