sensor smudge on k-x
If using fluid, dampen (not soak/saturate) a lint-free cloth Probably best to wrap it over the top of a cotton bud - the cotton should soak up any excess fluid), then gently wipe across the sensor, left-to-right, then up and down from the back of the sensor towards the front. If you can do this with...

sensor smudge on k-x
Hurray! It has gone. Was a tiny speck, and my makeshift removal attempt was to direct a jet of nitrogen (from a gas preservation system for wine) at it, which seemed to do the trick. Thanks for the advice.

I highly recommend the Arctic Butterfly, It spins a nylon brush with fine bristles which get a small static charge you then place it near, but not on, the sensor and any dust leaps off. :D:D:D

sensor smudge on k-x
It's somethng you need to get used to with digital cameras and it not really a cause for concern. There are any number of ways you can clean dust off the sensor, including all those mentioned above. I would be very surprised if it doesn't happen again - don't be too worried about it as it is easy ...

sensor smudge on k-x
If you used pressurised anything and got away with it then count yourself very fortunate. Usually what happens in the case of canned air is that moisture is blasted on to the sensor and evaporates very quickly.Not sure about nitrogen but still not recommended. It then becomes a huge and very delicat...

I may be missing something here Donald, but the website you have provided a link to actually recommends a variety of methods including pressurised canned air! All of the methods described on the website have already been mentioned in this thread. The truth is, as long as you use common sense, it...

POLL. How useful is the K-5 Low speed continuous 1.6fps
This is a 7 frames per second up to 30 frames camera. What would we need more for? I agree, the write speed of SDHC is the main restricting factor on all these cameras. Many class 10 cards advertise 30 mb/s but that's download to PC speed and not write which they often keep quiet about! 35mm s...

POLL. How useful is the K-5 Low speed continuous 1.6fps
"This is a 7 frames per second up to 30 frames camera. What would we need more for?" Who asked for more Bill? The subject is the abysmally slow Low Speed shooting of the K-5 (1.4fps using RAW). My K-7 did 3fps using RAW. That's a much more useful speed. "35mm size sensor cameras often have high ...

POLL. How useful is the K-5 Low speed continuous 1.6fps
"it would seem variable speed would be a good feature then, satisfying all users. " That would make me happy. The 1.6fps Lo speed is the one thing I really hate about the K-5. I know it's got a better sensor & IQ than the K-7 but I really miss the 3fps. I was going to sell the K-7 but now I'm...

POLL. How useful is the K-5 Low speed continuous 1.6fps
'Who shoots more then 30 frames in a single burst.....' Not many people here it seems. This kind of functionality is traditionally offered in the highest pro spec models aimed at sports pros and papparazzi. (Am I right that there was a Canon EOS1 model with a motor drive that shot at 11fps??!!!) ...

Dust resistance since moving to K5
Hi all, Three months in to owning a K5 DSLR(KR and KX's before that)I can report thast as well as my delight with the upgrade dust has become less of a problem. Many on here talk about rain resistance but not the dust when on location. I've not had to clean the sensor once, unlike the two entr...

Pentax K-30 in depth review
I would have thought a K3 that is 35mm equivalent sensor at 24 megapixels and APSC crop at 16mp would satisfy a lot of people and their lens collections. Given Pentax like Nikon rely on Sony for their sensors, if not the electronic trickery, it will depend on when the latest sensor is released to...

Pentax K-30 in depth review
It makes you wonder though - if this is the Kr replacement, what on earth have they got in store for the K5 replacement? I doubt simply '24 megapickles' will cut it, as the resolution improvement is negated as you raise the ISO. What do we want from the K3, that would justify a higher 'APSC flag...

Another K5 problem...
That is a f****ing disgrace IMO. I had the problem with the lens release, and then mysterious black specks on the sensor which Johnsons seemed/refused to recognize or even acknowledge. 8 weeks of back and forth repair time resulted in a very 'time to kick off' email to SRS. They in turn contacted Pe...

RAW batch processing in camera, post shoot
I was thinking there is an overhead for processing a Jpeg from the RAW sensor output and then there is an overhead in writing the jpeg to the card. The RAW will always be the same. I'm thinking RAW+ vs RAW, I'd not be so sure about RAW vs JPEG.
