K20D vertical banding
Yup, despite having had the sensor block replaced, I've begun to notice the issue on shots from my K20D again. I'm not impressed - some of the pictures were taken on honeymoon. It's not happening as often as the first time around, but then it seemed to become a more regular occurance over time..

K20d focus issue.
So when you adjust the focus setting are you adjusting the position of the sensor, or the setting of the AF system? If the latter, then manual focus should always be spot on and would offer a double check as to whether the system or the technique was out.

Could someone help an amateur with apentax 200k please
Hmmm.. That would be down to the speed of Light. Information from the furthest and nearest horses reaching the sensor, would be to all intents and purposes be the same. Speed of light is 300,000,000 m/s. So if the two horses were 10m apart, you'd need a shutter speed in excess of 1/30,000,00...

K100D Problem
Hi, I have a K100D that I have used for over 2 years now. I love it. My sister has the same camera. Out of the blue it stopped working. The shutter works when there are no lenses on the camera, but as soon as a lens in placed on the camera, nothing works. No auto focus, no shutter, nothing. ...

[quote:3496ace15f="pentaxian450"][quote:3496ace15f="Gwyn"]Where did you find this Nathan? Likely a Photoshop job. It looks incredibly like a K10D. More like the K20 as it has the studio flash socket on it! Then the K20 was incredibly like the K10! This is what the real looked like![/quote] ...

Shake reduction
Oh, and don't use SR when trying to pan a moving subject :roll: (Seem to remember this somewhere in the manual!) As long as the camera is still - use SR. If the camera is not still then don't use SR ;) Matt Don't you mean the other way around? If you think about it, the SR system is designe...

K10D and Twilight football
Pentax A lenses (which have the all important 'A' position on the aperture ring) can be used in any mode, everything, except of course focus, is still automatic. Pentax M and M42 lenses (with an adapter) you will have to use stop down metering. I tend to use Manual mode, set focus with the lens w...

K20 D body matters
[This thread has reminded me of that Canon DSLR that was involved in a mishap, the one where the lens had ripped the mount from the camera body. It'll be a while now since it was posted. Been looking for the link but cant find it, dont suppose anyone can remenber the topic title can they?[/quote] ...

2009 Predictions.......
To be honest I wouldn't be overly worried if Samsung decided to jump into the DSLR market in a big way and bought Pentax for sole use of the K mount and their customer base. Samsung have the money to throw at the market, much more so than Pentax (Hoya probably do but I don't think they want to). ...

2009 Predictions.......
Samsung are still developing a FF sensor, so, even if they pull out of DSLR's and concentrate on compacts (much as fuji have done), they will continue to develop sensors for DSLR's. So, if Pentax do a deal with Samsung, which they have done with the 14.6 CMOS, and do it with the FF, although they...

It could just be my eyes..
..but sometimes when I level shots using the guide lines in the view finder they come out with a slight lean. Is this just me, or is it possible that the 'moving' sensor doesn't seat back level? This is on a K200d.

It could just be my eyes..
The problem on the site, John, is the posts are from 2007 and refer to the K10. They seem to be missing as the links just direct back to the forum lists page. My question refers to my K200d, I wasn't aware that this had come up 2 years ago! So, is it a 'sensor at rest' problem or do all K200's do...

It could just be my eyes..
It might be an alignment issue between the viewfinder and the sensor, or indeed it might be a displacement of the sensor due to SR. Nobody has really come up with a definitive answer, but it is true that most of us have always tilted horizons from time to time. Some images have contradictory line...

It might be an alignment issue between the viewfinder and the sensor, or indeed it might be a displacement of the sensor due to SR. That's what I was wondering, with the K110 I don't have a problem, straight horizons and vertical walls (when sober!) But since starting to use the K200 this probl...

Old lenses on new gear
There are restrictions with old lenses, but that may not be a problem depending upon what you have in mind. If you are talking about Pentax lenses that's good as you won't get any compatitbility issues. Other makes should be examined carefully to ensure there are no extra bits (such as the extra ...

Old lenses on new gear
Hi Gromit, I think John's covered all the important points regarding use of older manual lenses (and they work well with modern DSLR's). As for getting a camera the size of your ME Super that has no "crop" effect on the focal length of your lenses, I'm sorry to say such a thing doesn't exist - fr...

Pentax K200D's disadvantage: viewfinder !
I upgraded from the K100D to the K200D and I have to say it's worth it. Not because of the 10MP sensor but it's even more feature-rich than the K100D. I especially like the self-cleaning sensor ( see at ) since I live in AZ where it's very dusty and keeping my sensor clean on the K100D was a huge...
