Originally posted by phler2 dude, i understand what you mean, in that yes pentax is probably going to be reluctant recognizing there is a problem that could be bad design/ production defect, if it happens outside the range of operating conditions.
that said, the specific problem we have here, and i am repeating myself, is not *due* to cold. it is merely (and not necessarily systematically) exaggerated by cold. and again, as i said, the problem often happens with temp higher than 0.
on an other point, your posts are not being any helpful at understanding the problem so to eventually debug it sort it out and give some important information to pentax engineer so they get a fix.
and sure you know why intel says their mobos may not work below 0?
no, it's not battery (except for portable devices)
perhaps its is problems related to condensations that could, be bad on the mobo. (but did you ever tried intel mobos cooled with liquid nitrogen, works great and far below 0
)
that said again : the k20d is definitely advertised to be weather proof and water resistant, and if condensation forms inside its electronics, then pentax would have to work on it given its on guaranty..
Dude? How '80s
We have been over this sort of thing ad nausem with various camera problems over the years. Someone has a problem, or a few people have a problem, and suddenly everyone has design "advice" for the manufacturers. Maybe you guys should all get together and design your own cameras.
Regardless, in a few cases, the cameras have had systematic faults that were indeed found by the users and widespread or even in all cameras of that type. In a few cases, those faults were fixed. In many other cases (maybe even most), they were not (like the dreaded K10D VPN and alleged K10D focusing issues).
I have been shooting Pentax since 1978, and have owned all but the IstD of the digital series from Pentax, so I have seen it all. If you think that these posts, or even emails to Pentax with images will make any difference, I am sad to say that you will be disappointed.
Time after time people have been advised to simply send the camera back for repair. If it has a fault that can be reproduced, and the fault happens while being used within the specifications and operating range of the camera (and it is still under warranty) then Pentax has an obligation to fix it.
If the fault is widespread or inherent in the design, the only real way to get the attention of Pentax is for lots of cameras to be returned to fix the problem under warranty.
To paraphrase a famous rock legend, "you will get no satisfaction" from Pentax for a camera problem here on an internet forum. This is especially true if you have not even bothered to let them try and reproduce your problem and repair the camera.
To get back to the problem at hand, I have given you the only situations I am aware of with similar banding in Pentax cameras, and after 15,000 + istds images, 10,000 or so K100D images, 20,000 + K10D images, and over 5,000 on the K20D so far, I am happy to say that I have never seen such a pattern, not even a single time.
Perhaps the issue is related to certain modes or shooting conditions, or attached lenses, or more likely, just a faulty camera that needs repair....
I guess at the end of the day, my "helpful" advice is for you to send it back for repair with sample images that have the EXIF intact and see what Hoya/Pentax has to say. I have had really good service from Pentax the few times I have had to use the repair service.
