cbgrey Posted May 23, 2022 Share #1 Posted May 23, 2022 (edited) Advertisement (gone after registration) I've noticed since I've had it that my M11 will seemingly randomly overexpose by a massive amount. The frequency has gone up and down but while out yesterday it happened so frequently that it's very worrisome. I've been chalking it up to it being a new camera and that future firmware updates will fix the metering but on closer analysis of what happened yesterday, I think it's not the metering and something else. The shots in the attachment were taking seconds apart from each other. All base iso 64. All with Multi-Field metering. The correctly exposed first shot is 1/500 @ f/5.6 (?) according to the EXIF. The overexposed shots are at 1/200 @ f/8 (?) according to the EXIF. If my math is correct those should roughly be the same exposure. The last (correct) shot is 1/4000 @ f/2.0. Any thoughts on what's happening here? I'm shooting this the same way I shot an M240 and an M10 and didn't have these issues so I don't think it's the photographers fault but who knows. Really appreciate any thoughts and opinions. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Photoworks Posted May 23, 2022 Share #5 Posted May 23, 2022 looks like operator error. probably a slip of the F stop since time was in A Link to post Share on other sites More sharing options...
cbgrey Posted May 23, 2022 Author Share #6 Posted May 23, 2022 Also... I confirmed Exp Comp was actually set to 1/3 under for all shots. Link to post Share on other sites More sharing options...

Do you have hybrid shutter enabled? if not there is your answer . Some time there is to much light wide open even at 64ISO by multiple stops. Link to post Share on other sites More sharing options...
hmzimelka Posted May 23, 2022 Share #9 Posted May 23, 2022 The M11 multi-field metering has proven to be inconsistent across different cameras and even in the same camera with other settings changed... My M11 got spoofed very easily into strong 1.5 to 2 EV overexposure using Multi-Field metering. Worse even with highlight metering. I changed my Auto Image Review setting from Off to Button Press and it seems to have helped. I have changed it back at some point and haven't nearly had as many overexposures. I cannot replicate this problem anymore, even though my camera did it often to the point where I could only use Centre-Weighted metering. Perhaps try centre weighted metering and see if that is reliable. If it is, I'm pretty certain this is one of the many M11 firmware bugs that Leica is working on to squash out. 1 Link to post Share on other sites More sharing options...

In continuous mode all shots keep the same initial settings so if you moved your camera with more light in the frame your M11 did overexpose normally.

Thank you for the suggestions. I'll play around with the settings. It's hard to reproduce as you note. I'm willing to be patient for firmware fixes if that's the realm of where this problem is. I've started to wonder if there's a mechanical shutter speed problem. Link to post Share on other sites More sharing options...

Seems like you did not shoot at f/8 then. You may wish to check the actual aperture as exif data are almost useless for that. 1 Link to post Share on other sites More sharing options...

There is a bug in the firmware and Leica is aware of this. But it seems not to be trivial to fix it. The recommended auto review setting can help - perhaps. 1 Link to post Share on other sites More sharing options...
lct Posted May 23, 2022 Share #16 Posted May 23, 2022 The only bug i'm aware of is Auto Review. Never got the least metering problem since i set it to Shutter Button Pressed but i may be missing something. Link to post Share on other sites More sharing options...
elmars Posted May 23, 2022 Share #17 Posted May 23, 2022 Some seem to have overexposure with multifield metering. I have none. But I have often overexposure in highlight metering, regardless what auto review setting. Link to post Share on other sites More sharing options...

I'm not interested in highlight metering but i'm not sure if the OP chose that mode actually. He could just set Auto Review to Shutter Button Pressed and see what happens if he did not do it already. 1 Link to post Share on other sites More sharing options...
hmzimelka Posted May 23, 2022 Share #19 Posted May 23, 2022 (edited) I'm pretty sure there must be some settings conflict that can trigger the problem. Like I mentioned, multi-field would often cause strong overexposure for me. However, it seems far less common now. I'm back to using multi-field and Image Review set to off. The most common cause for overexposure for me currently is when I review an image, bring the camera up to my face for either my nose or cheek to touch the LCD and shoot... often the LCD will not switch off and continue showing the last image I viewed, and the new image is often overexposed. Also, when shooting live view, the LCD image flashes brighter for a very short moment before the feed shows the exposure. I'm certain the Show Exposure Permanently (which is what I have set), on Half Button Press or Never, are settings that may also be contributing somewhere with overexposure problems. Whether one is shooting LV or not. Exposure preview settings definitely influenced how LV and non-LV metering wanted to expose my scene. I would get two different exposures. I very much want Leica to fix all these firmware gremlins in a timely manner but I suspect we'll be waiting longer than even patient users would feel acceptable.
