Pentax system guide
"Pentax FA 31mm f/1.8 AL, $835, (effective 46mm), a great lens from the film era, but ridiculous overkill for a small sensor camera with a tremendous waste of glass..." I think a few on here might disagree with that statement! Otherwise, some interesting stuff. Thanks for the link. Kris.

Mike Johnston K20 quote.
Mike Johnston has been comparing the full-frame warhorses, D700, A900 and 5Dii,....this quote caught my eye; To test that impression, I compared it with what is becoming my "Old Trusty," the Pentax K20D, a currently $810 camera with a really good APS-C sized sensor (and which I also don't own, N....

Mike Johnston K20 quote.
Within a couple of generations of camera I reckon the "full frame noise advantage" will be no more, it'll be interesting to see how many people are still willing then to pay the extra for a FF sensor? Pentax's decision to continue concentrating on APS-C could be seen in retrospect to be a very shrew...

I had a nikon a few years ago getting bits on the sensor, took ages to find out why as I was only changing the lens now and then. Had to send to Nikon as it was under warranty, they returned the D2h 3 weeks later fully cleaned with a letter asking me to send them my lenses for inspection, they fo...

You should perhaps try and send that pic to Pentax. It sure looks strange. Can you see the bits when looking on the sensor? Prieni

Make an overexposed photo with a high f-number, you will see almost everything that's on the sensor or the lens. You should be able to compare the result with that of the dust-alert. I hope you'll find out what it is.

hi people dry cleaned sensor today with no difference so the dust alert said, so wet cleaned and the dry cleaned again, this has made no difference again but now the dust alert is greyed out and wont do nothing i wonder if the camera is working properly:cry:

To be honest, I don't really need that dust alert. Dust alert isn't reliable. It tends so see many dust specs on a flawlessly clear sensor.

Just looking at those original 'etch-o-sketch' shots, and they don't look like random patterns, they are line drawings of your room, I'm sure. Rotate one of them 180 degrees, and crop out all the lens mount part of the image, then see if it looks familiar, with a bit of imagination. Camera bag...

Planning to buy a K20D
I have also been offered by the wonderful Park Cameras (based in Burgess Hill) the chance of returning my 20 day old K10D and swapping it directly (and paying the difference) for a new K20D with the £100 Pentax cashback, bringing the total extra outlay to around £100... i'm just not sure whether it'...

Planning to buy a K20D
The K20D is essentially the same as a K10D but with an improved sensor (more resolution, higher ISO range, better dynamic range) so the question is are you happy with what the K10D gives you? If you are then I'd say save your money and put it towards lenses instead. If you've found you're often say...

Planning to upgrade to a K20D
The JPEG's had more definition in the K20D even when I used her lenses and this would be due to the fact that the sensor is bigger I would say. We've done some prints at A4 from both cameras for comparison and the K20D has more detail and clarity.

"catch in focus"
This is interesting for me as I love to take Whitewater Canoe pictures and as it seems it will work with the K5. Will I need a Pentax A lens or can I take my manual 500mm M42 with the PK adapter? Also, can I use a manual TC? I never heard about this technique (but then again I am only shootin...
