K10 and K200d: Same sensors?
... Must admit for low ISO shots I prefer the output of the CCD sensor. .. please Mike, say a bit more about thanks

K10 and K200d: Same sensors?
The CCD sensor in the K10D/K200D combined to the Pentax image processor have a very "smooth" look at low ISO. It's something the CMOS sensor doesn't have. I kept my K10D for studio work just for that CCD "something".

K10 and K200d: Same sensors?
Most of my photography takes place in good light and I rarely shoot anything that moves very fast so the K10's sensor is ideal for me. My K5 is easier to use and has a wider dynamic range but the results I get from it are of the "mmm" variety rather than the K10's "wow!" If you see what I mean. I...

K10 and K200d: Same sensors?
... Must admit for low ISO shots I prefer the output of the CCD sensor. .. please Mike, say a bit more about thanks Basically what others have said in this thread. I always likened the CCD sensor CMOS sensors as glossy and matt photographs. The CCD always gave a glossier look to the images...

K10 and K200d: Same sensors?
.. thanks Mike and others; .. you learnt me something precious; .. but, could we conclude by saying that, as long as macro photographing is concerned (I know that Andrew (bwlchmawr) is not fond of it), in low ISO (that means with suitable light) CCD sensor (let's say K10D, K200D) gives better image...

K10 and K200d: Same sensors?
in low ISO (that means with suitable light) CCD sensor (let's say K10D, K200D) gives better image (especially better detail) than CMOS one No. It's hard to describe. The new CMOS sensors with umpteen megapixels give incredible details. But the "look" of the CCD sensor is different. In a class ...

K10 and K200d: Same sensors?
I think that CCD sensors weren't fast enough to handle video, while CMOS was, so everyone moved to CMOS. I couldn't care less about video and certainly wouldn't be happy at accepting a lower-IQ sensor just to accommodate it.

K10 and K200d: Same sensors?
I think it might have more to do with the rate at which information can be streamed from the sensor, the power consumption and hence heat generation and the noise behaviour. All this became more significant as pixel counts increased. I also understand CMOS sensors were lower cost to produce, perh...

K10 and K200d: Same sensors?
I'm no pixel peeper but I damned sure that the image quality from my K5 and K30 is superior to that of my K10 - regardless of which sensor is in which camera and regardless of what ISO they are set at. I'm not knocking the K10, I love it and it gives me some fine pics but I have to do less work on t...

K10 and K200d: Same sensors?
I tend to agree that at low ISO CCD is best, and think part of the reason is the shape of the tone curve. CCDs seem to be more linear than CMOS with no droop in the last few stops at the bright end, making them much more likely to blow out on highlights than CMOS, but if your subject's dynamic ...

K5 2S moire-Just for the record
Incidentally, using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire.

K5 2S moire-Just for the record
Incidentally, using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire. I am a bit astonished to read this. See e.g. http://www.dpreview.com/previews/ricoh-gr/9 - "Ricoh GR - F2.8, 100% center crop" (http://4.static.img-dpreview.com/previews/rico...

K5 2S moire-Just for the record
In what way are you astonished? It might be questionable whether or not color moiré is a problem for most pictures. However, it also might be disputable whether the absence of an AA filter really is desirable (an advantage). But this is not my point. Knowing you as an expert and experienced "test...

using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire I currently test a Ricoh GR from Pentax/Ricoh Germany. As the weather is not really good here, I also have looked at color moiré. Imho, it was quite easy to provoke problems: https://www.pen...

Advice re sensor cleaning function
I'd appreciate some advice from K5 users re the sensor cleaning function. I have 2 Pentax bodies: When I run the sensor cleaning function from the menu settings.... Kx - vibrates quite loudly and I can feel things shaking! K5 - nothing happens.... no noise and no vibration. Question i...

Advice re sensor cleaning function
The K-5 mechanism is ultrasonic, so you won't hear it.

Advice re sensor cleaning function
I need to go to the next stage and do a sensor clean with a swap....gulp! Have two marks that will not budge with the built in shake.
