Probably the best dry cleaning system available is the Arctic Butterfly from Visible Dust. A Rocket blower will, as others have said, simply move the dust to somewhere else in the camera. It's not likely to remove it. The Arctic Butterfly relies on a small electrostaic charge on its nylon brus...

As others have said it's most certainly dust or dirt on the sensor. What hasn't been mentioned is the reason your second picture is clear of dust is most likely because you used a larger aperture. The smaller the aperture you use the more dust shows up, and with reasonably wide apertures it is simpl...

I just bought a new Arctic Butterfly for my daughter-in-law. Same model as my old one but now it comes with lights:shock:. Not sure how useful they are but it looks impressive :lol:. I also use a loupe from Visible dust (makers of the Butterfly) to check the sensor.

I also got dust into the viewfinder the first time I used a Rocket Blower and had to have it professionally cleaned to remove this. However since then I have learned to use it correctly and have not had any further problems whatsoever. It's a shame they don't come with any instructions on how to use...

Wet cleaning may be the cheapest 'one-off' solution but bear in mind that the swabs are not reusable, and you may have to use more than one to get your sensor clean. If you use your camera a lot and change lenses frequently you might have to clean your sensor quite often, so this could mount up. Hav...

The Arctic butterfly (724) is expensive - around 80 GBP here btw, but it lasts you a lifetime, and will clear most dust quickly and cleanly. There is also the cheaper 788 which will do the job just as well. I have the swabs too - I used them first on my K-5 sensor having seen the Butterfly give p...

Thank you Mark for your exhaustive instructions. .... As Smeggy says you could just use the swabs every time but since they are fairly expensive and not reusable, trying the dry methods first can save you a bit of cash in the longer term (not so much in the short term because an Arctic Butterfl...

Settings/PP for shooting in snow
Snowy scenes also reflect a lot of UV light, especially in high mountain areas. Our eyes aren't too sensitive to UV light, but the sensor on your camera is, and that increases the blue hue you get on your pictures. Using a strong UV filter while taking the pictures will help in keeping the snow wh...

Settings/PP for shooting in snow
The lens coating and the coating on the filter in front of the sensor blocks the high-end of the UV at least, that's the part a normal UV filter also blocks. Seems to me a bit pointless to do that 3 times. What might help is a Haze filter, that one also cuts out the lower ends of the UV light.

K20D fuzzy image problem.
I had something very similar sounding with my K20D (along with every other fault going). The diagnosis was that an internal screw (I think from the tripod socket assembly on the base) had worked itself loose and lodged itself under the magnetic sensor plate, preventing the sensor from moving proper...

K20D fuzzy image problem.
The sensor is held in a particular position by the magnets whether SR is on or off. If something is stopping it being in that position then the SR will keep trying to move it to that position. That's the noise. I had this with a camera where initially it worked but then the frame that holds the ...

Pentax-F AF adapter 1.7x
I have tested the adapter with the A35-105 today, and the images I get are very good. It seems as if everything is just fine when using the adapter on the K20D... Maybe the stains on the glass do not have any negative impact on image quality when using the adapter with a 1.5 crop sensor? The adapter...

Pentax-F AF adapter 1.7x
Owch that is a good price ... still not sure I would be happy though. Just looked at mine and its crystal clear, that one seems to be going all round the rear element. Is the front element ok? Any chance of knocking the seller down to £100 because of the marks? Edit: have you tried cleaning it...

Pentax-F AF adapter 1.7x
If on the outside they may be the result of an attempt to clean the glass, and might come off if you use acetone or a proprietary lens cleaner. G That could be a possible explanation. I will buy some lens cleaner on Monday. Owch that is a good price ... still not sure I would be happy though. ...
