K20d or K7??
I've had all three cameras. Just a few of the K-7 advantages over K20D that I like: Electronic "spirit level". Video. Larger and more contrasty rear LCD. Live View button. Faster continuous shooting. Sensor shift (saves slightly re-framing when using a tripod). More reliable metering. ...

K20d or K7??
I would add to Pete's pluses for the K-7, K20D build is great but the K-7 is better :wink:, magnesium alloy body with stainless steel chassis. Much better live view implementation, great for macro work. Sadly the K20D's live view is crippled to the point that I disabled it (when I had a K20D)....

K20d or K7??
I would ask what you feel you need more, the various improvements in the K20/K7 over the K10, or some new glass? The K10 is a fine camera (...) Graham, Kris has a point there. I have also stuck with a K10, and got some better glass to go with it instead of upgrading the body. While I don't hav...

K20d or K7??
I'd just like to put in one good word for the K10D - CCD sensor! OK, that's two words, but the point is that I've yet to see the K10/K200/K-m sensor bettered at base ISO, so if you shoot all the time at 100 (and don't need the extra speed / facilities) then stick with what you have. :)

K20d or K7??
Still in love with my k20d...and still RTFM. :) No expert on this but I'm getting the impression that what with the changes in manufacture quality +/- and problems with the sensor I made the right choice to buy and keep this fabulous camera...what do you think???

K7 dropping in price....
Considering the K-7 has only been out around 8 months it seems a bit early for Pentax to be bringing out a replacement (not substitute:twisted:). The only reason I can see is because the K-x is hitting possible sales so maybe we will see a K-7s soon (basically the same but a different sensor).

Strong flare "effects" in polluted environment
hello, I'm in Cairo at the moment, and the other night I was out taking photos...when I noticed a luminous spot in one of the photos (mosque courtyard, lit background - spotlights on top of columnade). I probably wouldn't have noticed it if it hadn't been in the wrong place, that is, above the co...

Strong flare "effects" in polluted environment
A dirty sensor results in dark spots or marks at small apertures, not luminous ones. I think you are getting flare from the lens and filter. A hood may help to some extent, but you can't always avoid it. I would ditch the filter.

Downsides to Shake Reduction
I've not experienced it myself and I'm skeptical, but some users believe that SR sometimes introduces blur. Some also believe that the latest firmware (unpublicised update) helps to fix the "problem". SR takes a while to activate. The icon only appears when SR is ready. It shouldn't flash. The fi...

Downsides to Shake Reduction
I have yet to see any difference in shots taken with SR on or off when the camera is mounted on a tripod, other than the data saying stabilized or not ready. :shock: Well said, sir. Delving into my murky memory banks, I seem to recall that SR uses something called "Fuzzy Logic" which actually cre...

Downsides to Shake Reduction
some other factor I don't doubt for a moment that the tests everyone has done have given them the results they report. What I would say is that the instructions are quite explicit "turn SR off when on a tripod" so maybe they knew that would give the best results. If they had only said why we wouldn'...

K-7 long exposure bug?
With my K-7 with the latest firmware, after a 1 min exposure with Bulb mode, the camera is locked up for a further minute as if it is doing dark frame subtraction NR, but I have Slow Shutter Speed NR turned OFF! Is there something wrong with just my camera or do all K-7s do that? The sensor al...

K-7 long exposure bug?
The noise (interference) comes from the analogue circuitry of the sensor and the surrounding electronics. The higher the ISO, and the longer the exposure, the greater the amount of noise. The pattern of noise is random, I think, so I don't really understand dark frame subtraction. Someone else wi...

K-7 long exposure bug?
Thanks for the info, Neil & Bret. That's interesting. While active, can the temperature of the sensor be affected by the location of the camera? If so, perhaps, ideally, the camera should be left in situ on the tripod after all, rather than be packed in a bag while it does the DFS.

K-7 long exposure bug?
The K200D is the last Pentax that you can turn off all DFS. I use mine for astro work also. It is why I went with it, rather than a newer, higher MP camera. The only stupid things it that it use CCD sensor and those are more prone to noise at longer exposure compared to the CMOS sensor which Pentax...

What a fantastic camera!
will not effect any of your photography or does anyone have prove that it does? Doesn't the extra wiring on the sensor and other overheads compromise the still image? or was I dreaming I read that somewhere?
