New Sensor?
The LensPen company makes a version of their product for cleaning sensors: SensorKlear. It is the same as the their lens cleaning pen except it has a square soft felt tip instead of a round one to access the edges and corners. Not even Pentax say you that should never touch the sensor filter with...

New Sensor?
The SensorKlear does not always remove non-permanent stubborn marks though. That is what I have used on the sensor but it's def a scratch, you can just tell by looking at it in certain light .. a bit like a scratch on a cd or piece of glass. Pentax can sort it I'm sure.

New High-end SLR?
All we know for certain that Pentax has said during the time they launch the K10D that the next model (K20D) will have a better sensor or a better AF system, we now have the sensor so the AF will probable get some major improvements. In 2008 I've also readed an interview of Pentax that they wont do...

New High-end SLR?
Well then they need to "prioritise" in the most important sector and that is (fast becoming) the full frame/MF sensor market. Pentax has lost what may be called it's 'non-consumer' sales which were centred around very cost effective medium format systems. As yo will notice, both full frame DSLR'...

Poor Image Quality with My K20D
AF might very well be the problem, I was only thinking of taken it step by step. If you turn the SR off and manual focus the only thing that can cause the softness then is the sensor and/or the processing of the image. If the image is sharp you can turn on AF or SR and see what then happends. I...

Poor Image Quality with My K20D
Got my K20D back from Pentax service last week and they have replace the main board assembly and adjusted the focus, and the image quality is no better than before I sent it of. I was absolutely gutted. I called Pentax and got to speak to the technican who worked on my camera to see what they had...

Poor Image Quality with My K20D
I think Pentax are taking the pi** now to be honest. That is totally ridiculous. I really want to send mine away for the mark on my sensor to be looked at but Im wondering if I should just put up with it for now.

To K20D or not to K20D - that is the question?
Mike-P, Interesting comment about backwards compatibility. From what I've read, you need digital lenses for digital cameras because the light-gathering capabilties optimise the sensor light capture. I'd be interested to know what experience people have using film lenses on digital cameras and if ...

Focus problem in MF
For some subjects, the focus indicator will be inaccurate and then you can focus better by ignoring it. The image should be sharp though when it is sharp on the viewfinder. There could be some misalignment with the focusing screen, AF system or sensor, but then I would expect the problem with AF ...

Focus problem in MF
If the "78" in your first example was sharp in the viewfinfer then something in the camera is misaligned. I'm not sure whether that would be the focusing screen, or the sensor, or possibly both. It's probably happening with any AF lenses you have as well, but it isn't so noticeable with slower le...

Focus problem in MF
If the image is sharp on the focusing screen but not on the sensor, then there is a misalignment of the two. Have you cleaned the mirror, the focusing screen or changed the focusing screen? These things should never be touched unless you have the correct equipment and knowledge. Alternatively, th...

Focus problem in MF
I'm thinking you are right about the misalignments. I hadn't use anything very fast in AF, and certainly not close (shallower DoF). Although it puzzles me why it would be wrong if in the viewfinder it shows up correctly... Is the viewfinder at a different distance than it should be from the mirror?...

Not a Successor for K20D...a new concept...
Already to late for that Gwyn, If they want to launch new models this year they are already almost finished with the final product probable. Pentax really doesn't launch so much models compared to other companies. In the film age the only thing that improved was the auto focus and the metering ...

Not a Successor for K20D...a new concept...
In the film age the only thing that improved was the auto focus and the metering now we have many more things because the sensor is in the body and the image needs to be processed of course. But in my opinion metering and AF are the things that need improvement at Pentax. The other day I was shoot...

Don't worry, it's normal. Yes it's to do with the SR and floating sensor.
