The next >K7 spec sensor?
Is that the sensor off the NX10 detailed above? It appears to be a new model wih 14.2 mpix and 1080 video vs. 14.6 mpix and 720 video for the NX10 . And what is interesting is that it was apparently listed in the dslr section of Samsung's website, as highlighted above.

AFAIK the NX10 uses the same sensor as the K20D.

Do you know it's back-illuminated CMOS sensor? There is some news Samsung was busy making one.

Maybe Samsung or Sony, but why not Kodak? :D

The next >K7 spec sensor?
Some CMOS, CCD or other new technology, isnīt matter for me, such as 12MP or 15MP ... I expect better sensor than K-x. I prefer better ISO or better quality of picture. But I know, that Kodak make sensors for Pentax 645D, so we can expect some theoretical cooperation in this category ... ...

The next >K7 spec sensor?
10FPS on the sensor? Hmmm interesting. Surely the fps is based on two factors. The buffer of the processor and the ability of the mirror and shutter to move at that speed. Neither have been mentioned, only the A/D converter. Now, if the K-7 shutter/mirror combo is capable of these speeds, and t...

The next >K7 spec sensor?
10fps is only a speed indication it does not mean it does actually need to make those 10 shots :wink: Something like 60rpm doesn't mean it must make 100 revolutions in reality it can be it makes just one but in 1 second

K7 AF problem
My first move would be to clean the contacts on the lens mount with a clean dry tissue. I've tried cleaning the contacts and it does seem better, I can't test properly indoors though so I'll try it out tomorrow. Thanks for advise.

K7 AF problem
I've been in touch with SRS and spoke to James, they were very helpful as usual, told me to try cleaning contacts on camera and lenses and if it no better they'll send it to Pentax and loan me a K7 for my Farne trip,I can't ask for any more than that.

I cant see what point there is in returning the camera to SRS, they will forward it to Johnsons, Pentax's agent, on your behalf.

deciding on lenses
I am getting the K-7 in about three weeks. The trouble I have, is buying lenses. I could buy the 80-200mm 2.8 silver lens from Hong Kong and use it on a Pentax with an APS-C sensor then use it om my M.E. as well. The new lenses are made for APS-C sensors. I like the WR lenses, butit would be great i...

200d iso setting
ISO is a convenient way of expressing light sensitivity, since doubling the ISO setting corresponds to one f/stop or halving the exposure time. Also it is directly related to film sensitivity (the old ASA figures). I am perfectly aware that you don't change the sensitivity of the sensor, but mere...

200d iso setting
For the next discussion, why do DSLR's have "ISO" anyway, time a more appropriate and meaningful measurement was used like dB, as used on video cameras, and the difference between still and moving digital cameras is coming less than the difference between film and digital... simply because that's wh...

200d iso setting
Hmm, I agree with you to an extent - but it doesn't give any information about what the "optimum" level for a particular camera would be. For a random example, looking at 1600 ISO on a K-7 (base 100) it is +12dB of gain, but on a K-x (base 200) its +9dB - (could this be part of the explanation of th...

200d iso setting
magnification is a very dificult term to quantify, that's a whole different can of worms! I think you have explained yourself why switching to dB would be a very bad idea. Imagine trying to explain to a newbie why he had to shoot at +9dB with his K-x when his more experienced friend with a K-7 wa...

Sensor cleaning for my K-x
Hello all, Can someone please point me in a good direction for sensor cleaning on my Pentax K-x. Do the Pentax CCD Image Sensor Cleaning Kit's do the business or am I better off paying loads of cash for the professionals to do it? I'm usually pretty good with handling delicate tasks, so I'm no...

Sensor cleaning for my K-x
To be honest there is no such thing as a sensor cleaning kit since you never actually clean the sensor but the protective filter that's on top of it. :wink: For dust the Pentax kit will do or articbutterfly, you can also use a bellow but I never had much success with that. For greases you need...

Sensor cleaning for my K-x
I have never used any of those sensor cleaning kits, I find just using a rocket blower gets the job done without any problems. Set the camera into mirror up for cleaning and hold the camera face down and give it a couple of good puffs and that should be all it needs. Just be careful not to touch...

Sensor cleaning for my K-x
Thanks for the tips, guys. As far as I can tell it is only dust on the sensor, so no liquid swabs or anything needed at the moment. I like the idea of the blower as I'm not too keen on touching the sensor, but if that doesn't do it I may have to go for the cleaning kit. Thanks, Kev
