Something to Try (Only for the Brave)
If a blow with a rocket blower doesn't fix it I use Photographic Solutions sensor swabs and Eclipse E2 fluid. Had no problems at all though its a little scary the first time you do it. I must have cleaned my *istDS close to 50 times, I don't get anything like as big a problem with my K10D. They'r...

Chris[/quote]I use the Eclipse fluid and pads too, interestingly I've only had to clean my DS three times in three years. Are you particularly fastidious or do you work in a very dusty environment. This isn't at all a scientific observation but lately I've been using primes much more than dust pumps...

,[/quote]Mac, the Eclipse stuff is from the USA Ken[/quote] :oops: And to Screwdriver Chris, too.... I'm goin' too fast as usual. Thanks to all of you for the great input - and especially the confidence you've given me to give everything a go. I was about to trash my poor K110D an...

Hi Liam! Glad to hear the "wand" works well, - haven't got mine yet. Asked Daughter #2, who is also a photo nut, to get me wet wipes for Xmas. (Glad I didn't ask Daughter #1 as the wet wipes would be the diaper rash type and probably too big for the sensor.) :P I'm getting pretty good at i...

Hi Mac, Take a picture when the sensor is spotless again.. truly a sight to behold. When the annoying lumps got wiped with the wet wipes, I got crystal clear images.. so I guess that even without obvious crud, the sensor must collect a thin veneer of rubbish over time. If that veneer diffracts ...

K20D vertical banding
Check the EXIF data with PhotoMe and see if the SR had stabilised. It looks to me as if the SR may not have been stabilised and the banding is not quite as you say. EG: Have a look at the top left edge of the triangular shaped stone in the bottom of the pic that shows the problem magnified. It's ...

Just an idea but might it be the temperture... dark current? Only guesing now *sighs* it really shouldn't happen with such a camera.:( Does anyone have an idea it's the sensor or the in camera processing that cause this? The GX-20 has the same sensor but Samsung uses there own software if I'm...

I don't know if it's relevant, but there is some evidence of flare, so maybe it's a diffraction effect because of the light and the orientation of the microlenses over the sensor.

Prieni, I probably didn't explain exactly what I meant either. In some parts of your image the banding is exactly as you described, alternate light and dark lines. The part of the pic that made me question that description slightly is the bit I pointed out where that stone seems to have parts of the...

Thank you all for ideas and suggestions. John, the scene is very similar for both shots and the flare is there in both shots. So why should it influence one but not the other? Peter, Stefan, as far as I am aware the image is captured first (in full) and after the shutter is closed the readou...

Thanks Prieni, It's hard to disribe what I mean that i don't think you got me yet but with an picture it works better to word myself. taken from here I know it's Nikon but they had the picture I needed. As you can see the information from the pixels goes to the Column amplifers and eac...

K20D vertical banding
Are we talking RAW or JPEG when the banding occurs? I haven't seen a single image with banding from my K20D but I only shoot RAW. This occurs in RAW in my case. Looks to me like a flaw in the sensor/prime engine processing. Don't be too paranoid about this, I don't think it is that common a faul...

I wonder if it was just a bad batch of mainboards that were fitted:roll: or bad batch of cameras full stop..:roll: Most off the components are on the sensor with CMOS that's why they are cheaper and have more noise then CCD

Mine took more than two weeks to come back too. Pentax replaced the sensor and had to wait for parts to arrive. Seems to be perfect now. Went to Kew on Sunday and took a load of shots (mainly macro - Sigma 70-300) and they look stunning. Exposure seems to be more accurate too. The camera came back t...

Short visit to Watford today and my K20D is back in my hands after over month (ish) with Pentax, action described as "Repaired CCD-Block". Out of curiosity some look inside, same body, has come back with firmware 1.0 and flash memory erased (so default settings, shutter count in exif shows 250 clic...

Is that an argument to never change maker, ever? No of course not, and to be fair I didn't suggest it was. If you had a look at the test last week in AP "Is sensor size important?" then it showed that once past the very lowest ISO settings the smaller 4/3 was really very poor. Had it shown that i...

Is that an argument to never change maker, ever? No of course not, and to be fair I didn't suggest it was. That is true, you didn't. I did take the liberty to exaggerate a bit:wink: Trying out very carefully before buying is good advice in general. And I agree with your assessment of sensor sizes...

Having got the problem fixed, it seems a bit drastic to change marques. Presumably the Pentax was bought in the first place because it seemed the best option and all the lenses followed on. Soon the body will perhaps be upgraded anyway. What if the Olympus is no better, the lenses are certainly m...
