Inspection after sensor cleaning?
Everything on the sensor (lens) will become visible then. The high f-number insures that the light that falls on the sensor is perpendicular to it, so dust or anything else will block the light and will show up.

Inspection after sensor cleaning?
The K20D has a menu function to show you where the dust is on your sensor. The Pentax sticky tape will not remove oil from the sensor, Eclipse 2 fluid will. Don't forget you are not actually cleaning the sensor, but a piece of glass with special coatings on it which, amongst other things pro...

I had it twice with the K10D that the sensor failed or something in between since I got blank photos with a green line across it but for the rest it's working fine after a putting it on and off.

It looks like a sensor problem to me. I was going to suggest that it was a sticky shutter curtain, but then realised, it's a vertical run shutter so that's unlikely to be the cause. It should be repairable but might not be economical to do so. Have you tried another battery?

it's a vertical run shutter so that's unlikely to be the cause. I cant find ANY form of shutter in my K10 or 20, I assume the sensor just switches on and off. Is it getting late over there Peter:wink:

I cant find ANY form of shutter in my K10 or 20, I assume the sensor just switches on and off. Is it getting late over there Peter:wink: nope it has a shutter because switching the sensor on and off doesn't work. :wink: Use two second delay while not using a lens and you will see the shutter. ...

nope it has a shutter And so it does Stefan:oops:, I'm glad someone is awake and knows what they're doing. I've only looked inside and fiddled with the sensor for cleaning so never actually seen it. I always assumed it wasn't an actual physical shutter but rather the sensor which activated pixels in...

If it shows in live view, it's definitely a sensor (or associated electronics) issue. A full factory reset and/or a firmware reload might sort it out, but I doubt it. Worth a try.

If the sensor is a Sony creation then don`t be too surprised. Had a problem with a Handycam sensor and just before binning it I searched the net for any similar faults. Found that just about every range of camera had stuffed up sensors. Enquired and hey presto Sony doing a free out of warranty repai...

Cedric, GX20 use the same samsung sensor as the k20D and Canon develop their own sensor and I believe the problem was only with Canon, if they used a third party then others would have suffered as well. btw we never had much problem with the K10D senors and the models before that, they were or mo...

Hi Stefan, I have no knowledge of who uses which make of sensor. I was sharing some limited knowledge about a global issue with Sony sensors. Really glad to know that the K20 is from the Samsung company. I guess it`s a question of once bitten twice shy and I would never knowingly buy a product with ...

Yeah I know what you mean Cedric but the sony sensor is the mosted used sensor in DSLR land it seems. Pentax have used them, Nikon use them a lot, and sony of course so if sony was really that bad then we should have heard a lot more complains. Now the only DSLR that use a samsung is pentax and sa...

I am only guessing but the video camera sensor issue happened after a few years of ownership, four in my case. As I said I nearly binned the thing. So possibly a lot of people like myself thought that as the camera was well out of warranty that it was not worth repair. I was idly looking at the web ...

Whilst I take your point, Cedric, this sort of thing can happen to any manufacturer. Sony wouldn't have got where they are today if they made a habit of producing faulty goods. In fact you could argue that they will have learned from this experience, and are LESS likely than perhaps Samsung to p...

Hi all, first time here but I had to post this. I was trying the setup of K20d cabled to the main light, the second light on sensor and got the same problem as everyone seems to hit - one flash then nothing. OK - heres the solution to avoid any extra expense for radio links etc. After you t...

istD L2 no power no matter what. Please help.
Sci, welcome to the forum. As a starting point I would try cleaning the camera's battery contacts with something more substantial than air - possibly a cotton bud moistened with a drop of alcohol or electrical contact cleaner - I'm fairly sure that someone else on here will confirm that this proc...

K-7: AE-L and Horizon Correction
A suggestion... I think I would do some tests with Shake Reduction on and off and also Composition adjustment. These features are all connected with the sensor motion hardware which is also used for Horizon Correction.

Spots visible in viewfinder but not in photo
I have just seen spots in the viewfinder but these do not show in photo. I have cleaned the mirror and screen above this but spots are still showing. Should I get the camera cleaned inside? Or ignore it? Could there be a possibility of these specks or spots getting on to the sensor? Any advice or h...
