Re: Crap! K7 Sensor Problem
2009/7/29 Mark Cassino markcass...@ymail.com: Thanks - that looks exactly what I have going on. Now I wonder if I should replace the camera - but not *ALL* K7's have this problem - right? I checked a number of exposures from mine yesterday and found nothing. But then again ambient temperature is most likely a bit lower in these parts right now...

Re: Crap! K7 Sensor Problem
Mark, IIRC, someone had a blogpost somewhere about K20D having a systemic fault that popped up in the same area for all affected cameras. In case this is another one of those, would you mind describing where the band occur in your images? I'll check mine as soon as I get back from office. Thanks for the heads-up and fingers crossed for a quick solution. It's crap indeed. :-( Jostein 2009/7/28 Mark Cassino markcass...@ymail.com: I got a new job and have been on the road traveling for 5 of the last 7 weeks - which has left very little time to give the K7 a real workout.

Makes me remember I had such a problem with my istD in Greece, years ago: the embedded Jpeg was OK but the RAW was not. It was the very singe time this happened to me. Maybe a card write problem.

Re: Crap! K7 Sensor Problem
- Original Message From: P. J. Alling webstertwenty...@gmail.com Let me preface this by saying that if I had just bought a K-7 and noticed this I'd be disturbed, if not angry. However in a lot of the examples the issue is hard to see even in the enhanced images. Under normal circumstances with a good exposure, not trying every Photoshop trick to wring a bit more shadow detail out of an image, you might never see this. P.J. - It is a fiarly subtle problem, and I do wonder if it would show up in prints. On the other hand - knowing it's there will drive me crazy. Here's a similar crop from the frame before the one I posted yesterday - straight from the raw file with no adjustments. It's still pretty visible, at least on the screen: http://www.markcassino.com/temp/IMGP1266.jpg - MCC - - - - - - - - - - - - - - - - - - - - Mark Cassino Photography Kalamazoo, Michigan www.markcassino.com www.calarti.com - - - - - - - - - - - - - - - - - - - - -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: Crap! K7 Sensor Problem
I have struggled to reach pentaxforums all day. Finally, I was able to read the posts today. From page 2 - falconeye in Munich General comment ... 1. this is no stitching artifact (because it is possible to get 3 lines in extremely rare cases) 2. You normally should only get it with a hot sensor (red thermometer appering in LV or movie mode). With a red thermometer, it may be considered normal extra noise. Without a red thermometer visible in LV, it shouldn't emerge in images. Even with the red thermometer, the line is very faint. 3. The red thermometer needs more than 10 minutes constant LV/movie recording to appear (except in hot sunshine). And disapperas rather quickly. 4. In normal photo operation (with breaks in between invocations of LV), the phenomenon should not be present at all. It is not necessary to avoid LV. If it is, then the camera is defect. None of my images (execpt for the one where I provoqued the issue) has this and I used LV a lot. So, an overheated K-7 sensor may exhibit a faint vertical line with additional noise. This is acceptable to me (can be easily removed for a keeper). Nothing to panic about. Doesn't minimize your problem Mark, but sounds like a way to provoke it. Regards, Bob S.

Re: Crap! K7 Sensor Problem
Did you happen to run the Pixel Mapping procedure? Not that I think in your case that it will repair your problem, but it will try to correct bad pixels. In your case I think it might be a bad connection between the sensor and it's sub-ass'y.

Yesterday I got that chance, and shot about 600 exposures out in the field. As I worked on them I realized there's a light colored band running through every single image I shot yesterday. Looking back over all the images I've shot with my K7, the same problem shows up in every single image. Here's a sample - actual pixels of the very last shot I took yesterday. (Apologies - the shot is not properly focused.) Guide arrows help identify the hot pixel column. http://www.markcassino.com/temp/IMGP1267.jpg It's a subtle problem, but a real problem.
