Not a dirty sensor
I'm not laughing, I have a bit of a strange problem, where I get, what I assume is dirt on the sensor, but it only appears intermittently, maybe on 10% of shots, and not even on consecutive shots, note the top R/H corner, I assume it's a virus I caught from 'Clarky', where one of his spiders ju...

I'm not laughing, I have a bit of a strange problem, where I get, what I assume is dirt on the sensor, but it only appears intermittently, maybe on 10% of shots, and not even on consecutive shots, note the top R/H corner, Is it always in the same place? If so, then I think it has to be something on...

Not a dirty sensor
Usually dust only becomes visibly when using small aperture openings together with the neutral background you mentioned. With my DS I had dust on the sensor which was only visible at f11 or smaller. If the thing is sitting right on the sensor, and presumably simply casting a shadow on to it, from ze...

Not a dirty sensor
If the thing is sitting right on the sensor, and presumably simply casting a shadow on to it, from zero distance or thereabouts, why does the aperture affect it? Well, it is not sitting right on the sensor. It is sitting on top of the filter (i.e. the surface of the sensor assembly) and therefore a ...

Not a dirty sensor
Well, it is not sitting right on the sensor. It is sitting on top of the filter (i.e. the surface of the sensor assembly) and therefore a little bit off the sensor. At wide apertures more light can go "around" the sensor, therefore softening the shadow. Yes of course. I'd forgotten about the filte...

K10d and automatic ISO change criterion
I would expect that the criteria for selecting sensor sensitivity would include some or all of the following: 1 The focal length. A longer length demands a higher shutter speed, so either sensitivity or aperture must be changed to compensate. 2 Lens MTF. This information is included in rece...

Upgrade Path advice wanted
Dynamic range should be the same as they have the same sensor.

Dynamic range should be the same as they have the same sensor. Thanks for confirming this. I thought I'd read as much, but wasn't sure.

They have the same sensor, but the processing is different. Apparently, the K200D is less noisy at high ISO than the K10D.

New Body, New lenses.
I have had the same type of conversation with another un-named pentax dealer. Now my question is really on a different level. I wouldn't mind updating to a full frame body, as long as it had the type of 'reduced size sensor' to accomodate also regular APS-C digital lenses, which wouldn't otherw...

New Body, New lenses.
There's obviously no reason not to keep producing the smaller sensored models, keeping the owners of the D lenses happy. Well, it's funny how it goes. I've now taken more digital pictures with my K10D in a year and a half, than film pictures with Super A and ME Super in 22 years. The average q...

I agree with you Chris, I have no need of a 35mm sized sensor, but I guess if enough people need (or more likely want it), then there's a market for it. Hopefully this will be a K2D, and there'll be a K30D, and a K40D, and a K50D..., keeping us APS-happy users satisfied for years to come. Dan

New Body, New lenses.
why go backwards when designing a new sensor? the old 35 film format won't fit on the new widescreen tv/monitors. If your going to pack more pixels onto a sensor, then it would make more sense to either go square, or wider, than aps-c. (or 24x36 for that matter). I for one hope that they sav...

If your going to pack more pixels onto a sensor, then it would make more sense to either go square, or wider, than aps-c. (or 24x36 for that matter). Another vote for a square sensor from me please! I always liked the square format and you could allow the user to select other ratios if required (obv...

News from Pentax
Hello Everybody! Right, this is big news... and its all 'secret' stuff coming out from a Pentax rep. during a pentax day chat, can't say where... - The DA* 60-250mm is going to be out at photokina, so September. Retail price.... £899 :shock: - At photokina Pentax will announce a new b...

News from Pentax
What do we think? I want to update one of my K10's, and I want the K20 sensor, and a faster AF, fps, ISO performance, possibly AF in live view.... Let's hope that Pentax's management reads these forums, instead of trying to compete with c. & n. If there's a K30D with these features, say, middle...

cleaning the pentax k10d focusing screen
Hi i just wondered if anyone knew how to clean the focusing screen i have a couple of specs of dust there.I checked the sensor and its all clean the dust specs do not hamper my photos its just when you look through the viewfinder you can see them. Thanks for any replies

cleaning the pentax k10d focusing screen
Leave them alone and they'll go home! The more you scrub at camera screens and lenses the more damage you do! You should see the state of the gear of the other press snappers when I go out on jobs-they don't worry about an inch of dust-it's only the amateurs who worry!
