k200d 5 minute high iso exposure test

Since the topic is of a low importance wanted to contribute to this tread:
But i got an error that the thread is older than a year and then all my written text disappeared, i'm presenting and angry short version of it.

Maybe someone finds this useful. I did a 5 minute (300 s) long exposure test. iso 1600, all NR off (high iso and slow speed).

I was pleasantly surprised how well the k200d did for its age.

First one with lens cap on. Second one with lens cap, viewfinder cap and camera in thick dark bag. It is interesting to see how big of a effect stray light can have. I suppose the second shot doesn't have any light leaks, and this is from something warm inside camera. Still the colour is similar to areas in first picture, but the better defined line pattern in those spots could indicate local difference (electronics nearby, worse CCD quality). Both report t=21C in exif.

I agree, the K200D is a fine camera, I like it.

Those are some hot spots from inherent noise - hard to control that. But indeed the K200D is very capable of doing very long exposures to good effect.

Additional note on the VF cap. When doing longer 30..60 sec exposures in broad daylight with IR720 filter, the brightest part (horizontal band) can become visible. So it is beneficial to use VF cap even in shorter exposures if there is a change of stray light.
