symmetron Posted May 12, 2011 Share #1 Posted May 12, 2011 Advertisement (gone after registration) Look at these 2 photos. Same exposure and ISO, but the IS (which I don't use, but was just checking it out) gave a totally different result. Is this normal for X1 with its digital IS or is there something wrong with THIS camera? Exposure info: ISO 1000, f/2.8, 1/30. With IS is darker than without IS. Histograms are different also.

jippiejee Posted May 12, 2011 Share #2 Posted May 12, 2011 Tried it here, both images look exactly the same though. Can't repeat your results... Link to post Share on other sites More sharing options...
Guest badbob Posted May 12, 2011 Share #3 Posted May 12, 2011 IS won't change the color but anything else can, like a few seconds pause between shots and even the tiniest movement of camera or anything else. Link to post Share on other sites More sharing options...
Allnm Posted May 13, 2011 Share #4 Posted May 13, 2011 I just tried a similar shot with your settings and images looked the same. Is this a repeatable result or a one off? Allan Link to post Share on other sites More sharing options...
lykaman Posted May 13, 2011 Share #5 Posted May 13, 2011 Possibly the Sunlight reflection on the table! maybe a setting was altered without realizing! Did you know that in “IS” the camera takes 2 images & combines them... thoughts only thoughts...... Link to post Share on other sites More sharing options...
symmetron Posted May 14, 2011 Author Share #6 Posted May 14, 2011 I exchanged the camera for another one, and the new camera also under certain circumstances, will underexpose using IS. Apparently, it only happens in shots where it's dark, and I mean no dominant light source, yet still within the IS operating parameters. It only happens under certain circumstances, but generally, the IS performs acceptably. Yesterday before exchanging the camera, I spoke with Mark Brady at Leica USA, and he had not heard of the issue. Today he called me back after speaking with Leica Solms and they are interested so I sent them some photos replicating the issue. There's a concern apparently that there's some software quirk in the processing algorithm I guess especially since it happened on two cameras. Fortunately I don't really use IS, but I was concerned with the original X1 that there was an issue. Apparently, it's a "class" problem that Leica will sort out eventually.
