K5 sensor overheating/on way out?
Any chance it's something to do with interaction between the filters? Coking filters are known to cause purple colour casts. The marks look like smears; I would have expected sensor issues to manifest themselves as dead straight lines? Cheers John, I'd seen the Sony heating issues but that seems to...

It looks more like reflections from a filter than sensor problems. Try a night shot without filter to see if the problem arises again.

K5 sensor overheating/on way out?
I can't believe the IR remote would have anything to do with it, but.. Don't take this the wrong way, but if this indeed proves to be a camera fault I hope this it's peculiar to your K5 and not indicative of another K5 ice-berg! I'd like to go along with Yves suggestion, but the marks seem too...

If it was reflections the orientation on the second image would be different

It looks more like reflections from a filter than sensor problems. Try a night shot without filter to see if the problem arises again. Yves, I cleaned the B+W ND110 and used a different ND grad between shots, in addition to changing location, lighting direction, sensor orientation etc. Reflections...

Light entering via the viewfinder? Did you have the viewfinder cap on?

Did you do a "wet sensor cleaning" before taking those pictures?

I had similar problems with my B+W 10 stop. I had not used the eyepiece cover, I think that this way well be the problem. :( I have tried again, used black cloth, as forgot cover on 2nd outing :oops:, no problems :). Hopefully this will stop these problems for you too.

K5 sensor overheating/on way out?
Did you do a "wet sensor cleaning" before taking those pictures I'm thinking the same as Yves on this one. Looks like possible streaking caused by uneven application of cleaning fluid. The lines are not dead straight and are along the length of the sensor which would be the natural direction to c...

Sorry, sensor hasn't seen a rocket blower, let alone a wet clean.

Photome will show you the sensor temperature on the original file.

Sorry, sensor hasn't seen a rocket blower, let alone a wet clean. Afraid you were going to say that. :? Oh well ...I may have to eat my words, the streaks do appear to brighter at one edge fading off across the frame, while the streaks seem mostly parallel the broader centre band appears off ....

Photome will show you the sensor temperature on the original file. Exif is intact - I can see 'camera temp' listed, warmer than ambient but under 20 degrees? Guess it's a process of elimination to exclude reflections as the cause first. Cheers Mike - sadly the Mrs came down with a viral infection...

Ok, so the sensor isn't overheating then. I think alig is pointing in the right direction.

K5 sensor overheating/on way out?
Just saw this thread. I noticed something very similar on my K-5 when I was playing around with an IR filter. In weak sunshine the exposure was several seconds with the lens stopped down, and there was a distinct band of light across the bottom of the frame. It was simply light coming in via the v...

K5 sensor overheating/on way out?
Not been able to get out and test further though can't reproduce it indoors, so beginning to think the PU common sense wagon is right. Could be a design difference with the K7/5 body as I've been utterly careless with respect to covering the K-x viewfinder before now with no ill effects. Will ...

K5 sensor overheating/on way out?
Sorry to dig up an old thread but it has been found in a web search and posted elsewhere, so thought I should add a definitive (and happy) conclusion. After more testing it appears these streaks are, as suggested in the thread, light leaks through the viewfinder. The simple bit of fabric that ha...

K5 sensor overheating/on way out?
Unfortunately I missed this thread, I could have diagnosed that immediately. One of my useful photo accessories is a lump of blue tac to stick over the viewfinder to prevent this light leakage with long exposures.
