what do you think stain??
Thanks for so fast response. I was doing this "dust checking" on the sensor good few times and picture that camera taking looks fine(no marks on this white screen). Using this option in my camra "dust removal" did't help at all. Clean with? dust air blower? or do i need something better sorry f...

arctic butterfly is probably the most preferred tool for getting the dust off your sensor.

what do you think stain??
What do youse think guys? Doesn't look like a stain based on the fact there is no halo. Although it gets fainter, I still can pick this out down to F5.0 but is more prominent as the aperture closes. It's definiately sensor as I see it across lens Heavily cropped picture of a grey sky at F22

K5 High ISO banding?
I think your subject and lighting are bound to show any tiny flaw in the K5's sensor at these settings. Here's a test shot at 1/200th, f4, and ISO 51200 I made a couple of nights ago. The light was from a low power energy saver bulb. I'm quite happy that if I ever needed this extreme setting, ...

K5 High ISO banding?
Thanks guys for all the input :-) I sent some raws to JohnBee over at PF to check out and like others have said my k5 seems fine and they don't see the banding too - I just think it was a problem caused by my poor noise reduction (inexperience), and me over examining my photos and wanting to find...

K-X, dust on sensor - help?
Hi, I'm having a tough time with my K-X. I bought the camera perhaps 6 months ago, immediatley fitted the kit lens (18-55?) (in a relatively dust free environment) and started shooting (with no issues for the first few months). Last month I went on holiday, took a few hundred photos - and eve...

K-X, dust on sensor - help?
No idea of whether it's deemed good practice, but I had the same issue and just puffed the rocket blower up into the viewfinder area (in a careful controlled manner), holding the camera with the mount facing downwards so hopefully any 'bits' fall out and not straight back on the sensor! It worke...

K-X, dust on sensor - help?
Thanks - I'll have another go with the blower tonight. Still unsure how best to shift the stubborn dust from the sensor itself though. Seems I'm just unlucky having such issues without even changing lenses :(

K-X, dust on sensor - help?
Arctic Butterfly seems to be quite popular, and avoids the need for a wet clean or blowing crud up into the viewfinder. Perhaps that is the way to go.

K-X, dust on sensor - help?
Unfortunately debris gets everywhere. When we used film we had to "spot" prints to remove white spots, so with digital it's much better than that at least. Use the dust removal system of the camera several times and if that doesn't work then hold the camera so the opening is pointing down, open t...

K-X, dust on sensor - help?
Welcome to DSLRs. My K-r has exactly the same problem but in my case repeated efforts with a rocket blower has failed to shift the dust. It is very annoying and so far a solution evades me. :(

K-X, dust on sensor - help?
I've read several do/don't guides online (many conflicting). Advice varies from "only ever use a blower" to "use a clean cotton wool bud to wipe the sensor" - and all levels inbetween (including the £100 statically charged brushes). It seems the sensors are not as delicate as one may think (if han...

K-X, dust on sensor - help?
Fair enough. You could have a professional clean done, but the rocket blower should work in most cases, eventually.... Pentax make a cleaning kit, but there are others. Extreme care is a good maxim I think, but plenty of users do clean their sensors. Some complain afterwards of streaks and scratc...

K-X, dust on sensor - help?
I use the Arctic Butterfly, but I have a Rocket Blower and swabs too. The Butterfly gets rid of most crud successfully. Nerve racking the first time you do it, but fine after that. That said, I have two stubborn bits of crud on my K-5 sensor. I never really had a problem with dirt before - nothin...

K-X, dust on sensor - help?
Interesting you too have dust in the viewfinder as well as on the sensor. Both my K100 and K10 suffer from this, despite the latter having over seventy seals! I think the muck gets in through the dioptre adjusting slider. It doesn't affect image quality, of course, but is annoying and distracting ev...

My K-5 has dust in the viewfinder too. I can live with that.
