K10D dust removal - does it work?
Pete; where abouts on the sensor are you looking? dont forget it'll be upside down in relation to its position on the print.

K10D dust removal - does it work?
I had a few large spots of dust on the sensor since the day I got my K10D. Been using the dust removal feature about a dozen times, but they just wont go. So I locked up the mirror and blew in some air and the image is now spotless. I can certainly hear and feel the mechanism shake, but has anyo...

K10D dust removal - does it work?
I had some dust, but got the sensor to do a couple of extra cleaning cycles and that sorted it. If the stick pad that holds the dust is at the bottom of the camera you probably need to hold the camera level when you do it, or the dust will fall onto the back of the lens (if the camera is benig held...

If dust is going to fall on the sensor, then whether the camera's a week or a year old fall it will. However, with our *istDS bodies we were very lucky and never had to clean the sensors. If it annoys you, why not try the blower brush method. But first I would set the camera to perform dust remov...

My first Problem with the K10D DUST !! please read
I always have dust. Lots of it. On the *ist-D I had platefuls of it and even with careful cleaning it seemed to creep back in. Having seen Keith Henson's CCD (ephotozine user "keithh") on his Canon 1DsMkII I don't worry so much - his was the dustiest sensor I've ever seen :P Just takes ...

Pete, I'd worry more about that big arrow. It really sticks out. I might not have even noticed the dust spot, if it weren't for that big arrow. What could cause such a thing? Marks on the sensor? Confused sky writers?

Pete, The Rocket Blower did the trick for me as well. I do have to say, the K10D sensor is otherwise spot free. Even with manual cleaning, the istD never got completely clean. If all I need to do is blow some air for the big stuff, I can certanily live with that! Matt, I have a sensor clea...

My first Problem with the K10D DUST !! please read
Pete, If you use a blower, make sure you use a Rocket Blower with a one way inlet valve. I used a bog-standard one once - all it did was add loads more dust particles on the sensor, giving a black snow-storm effect! :shock: When the blower doesn't work, have personally used Digi-pads and ecl...

My first Problem with the K10D DUST !! please read
I recently did some product shots for a customer, using my studio flash and aperture of f/16, with a white background. Should have given the sensor a quick blow first and saved myself having to clone out numerous spots and a line (a small fibre) from every shot. Stupidly I packed everything away b...

Panning with SR
as I understand it, the SR system works by using sensors in the body to detect camera movement, and moves the CCD to compensate. Panning involves a lot of movement in one direction, so there are two possibilities as to what will happen that I can see 1. The SR gets confused, throws it's rattle...

Panning with SR
2. The SR throws the sensor to full horrizontal deflection very quickly, but vertical deflection is still available so it continues to work and provides a useful bonus That was my thought as well, and formed half the reply I made in the other forum, the guy hasn't responded yet.

Panning with SR
Interesting topic,... My undrstanding of the Pentax info re the 'SR' is that the sensor movement is quite small and is only intended to counteract the small hand movements present in purely hand-held use of the camera. Since panning with a moving subject is a fairly extreme movement it seems ...

Not exactly ;) Pentax cut down on the number of stages from the CCD to the ADC. Normally you'll have an amplifier to set the ISO rating between the CCD and ADC. From what I gather, Pentax have no intermediate amp and so the ADC sees the full dynamic range all the time (ie all the ISO ratings). Whe...

It seems like we are talking the same things by different words. :wink: IMHO true 22-bit ADC is not a problem only in laboratory (i mean result, not just a fact it is). My calculations of the chip was just an estimation of approach more so we have no information about the sensor.

I'm still learning myself, so please take with a pinch of salt. If possible I'd have moved to the left to try and take out the sign post and possibly get more water into the scene. Why do you need to clean the sensor? Image looks fine to me.

Pentax Ist DL2 Focusing screen dust
Many thanks for your detailed reply. Having had a an MX with an interchangeable screen, even when they are designed for easy removal I completely agree with your cautions. Has anyone any experience of the Green clean sensor cleaning kit? Not at this stage in respect of cleaning the actual sensor,...

Hi Tom, Excellent shots again! You do realise Crickets can bite, don't you? :wink: Image 4143 is especially good, showing exr=tra detail around the mouth and antenna, whilst keeping the eye sharp. Looks as though your sensor could do with a quick clean though, working at these small apertur...

Very well done, Tom. Look forward to more. However I'm intrigued as to where you found the cricket, and the earlier ant, in the UK at this time of year. Do you live near a zoo with an insect house :?: by Daniel Bridge Looks as though your sensor could do with a quick clean though Well spo...
