Originally posted by raz MAC can you investigate why the K-5 image look more exposed than the K-7 ? Even the wall behind looks brighter ? My guess is the sensors have different sensibilities , I mean iso 200 is not iso 200 for both sensors, even if the display sais so ?
I just did a quick n' dirty comparison.
With the camera in manual at ISO 100, 5 sec., f8 with all camera settings absolutely identical the k-7 image was noticeably darker, as already observed with most of the shots in this thread. The histograms back up what we're observing. I adjusted the k-7 ISO up 1/3 stop at a time until they appeared to match, and at ISO 160 the histograms are nearly identical.
I'm afraid I've run out of time to do any further testing right now.
Hopefully one of the other K-5 owners here can help answer this.
