JLoh Posted January 8, 2016 Share #1 Posted January 8, 2016 Advertisement (gone after registration) Recently purchased a new Q and very impressed with the live preview. However, there appears to be a glitch in that only negative adjustments are shown in live preview, with no change in exposure being shown for positive adjustments. I've tried this in all modes including fixed ISO, full auto, manual, aperture priority, etc. Have also reset camera several times and checked that I have firmware 1.1 installed. Nothing seems to work! Any help would be greatly appreciated! Link to post Share on other sites More sharing options...

Stephen55 Posted January 8, 2016 Share #2 Posted January 8, 2016 Hi, I started a thread in this subject a couple of months ago. Seems to be an ongoing issue that I hoped was a fault with the camera I returned. Have you tried it in full daylight, as others have found the problem only occurs in dim light conditions? Whatever, I still find this unacceptable, and am quite concerned as I have a second camera on order. I do hope Leica are aware of this and are taking it seriously.

fotografr Posted January 8, 2016 Share #3 Posted January 8, 2016 I just took delivery of a new Q today and do not experience this issue, even in very dim light. It appears not to be something that affects all Q cameras. Link to post Share on other sites More sharing options...

It appears not to be something that affects all Q cameras. Thank you for confirming your Q does display over exposure on the EVF and LCD even in poor light. Others are finding this not to be the case, and are suggesting this is a limitation not a fault. I cannot agree, so good to know yours is working as expected.

mcausus Posted January 13, 2016 Share #5 Posted January 13, 2016 I just took delivery of a new Q today and do not experience this issue, even in very dim light. It appears not to be something that affects all Q cameras. On my Q (FW 1.1; f1.7; aperture priority mode for shutter speed, and auto ISO), I was changing the exposure compensation last night (in somewhat dim light), and also noticed that the LCD monitor would gradually darken with increasing negative compensation, but only lighten with positive compensation up to a setting of +1. Do you experience increasing LCD brightness, all the way to +3? I have yet to try this experiment in full brightness . Hi, I started a thread in this subject a couple of months ago.

Found your thread here: http://www.l-camera-forum.com/topic/253266-exposure-compensation-preview-aelafl-metering-memory-lock-problems/ If you've received another Q, does this phenomenon still occur?

jaapv Posted January 13, 2016 Share #6 Posted January 13, 2016 Does this mean you are trying to judge exposure by the LCD/EVF image? If so, that is not a good idea. The histogram is the tool of choice. Anyway, how does the camera react when the exposure is set manually? Link to post Share on other sites More sharing options...
SamuelF Posted January 13, 2016 Share #7 Posted January 13, 2016 Advertisement (gone after registration) I also experience the same issue with exposure compensation. The histogram is not of any help since it reflects the exposure of the image in the EVF, not the exposure of the image taken with adjustments... On my Q it only happens in Aperture priority for everything darker than EV3: then neither histogram nor EVF can reflect the correct exposure of the final picture taken. In manual priority the same thing happens but only for EV1 (all at ISO 100...). It is not a huge issue but can be problematic in some low light situation, especially for manual focusing. And we can always rely on the exposure level indicator that displays the accurate exposure. Link to post Share on other sites More sharing options...
barjohn Posted January 13, 2016 Share #8 Posted January 13, 2016 I find on mine it does display dimming in the negative direction to -3 in good or low light but in the positive direction it does go to +3 in good light but no change to display beyond +1 in low light. The image taken does reflect the over exposure in low light it just doesn't show on the LCD/EVF. Link to post Share on other sites More sharing options...
kuspen Posted January 13, 2016 Share #9 Posted January 13, 2016 Yepp! Mine show exactly the same symptoms.. Link to post Share on other sites More sharing options...
@McLeica Posted January 13, 2016 Share #10 Posted January 13, 2016 It appears to be condition dependant. On mine I always get negative exposure compensation showing on Liveview, but positive compensation will vary from 0 to +2 and never further and sometimes not at all. This occurs from lighter conditions to darker conditions from what I'm seeing. Odd. Link to post Share on other sites More sharing options...
JLoh Posted January 13, 2016 Author Share #11 Posted January 13, 2016 Pretty clear from the posts above that I'm not the only one seeing no change in live preview when increasing exposure compensation in low light. Would be great to find someone at Leica to address this issue. Tried looking on the Leica Camera website for someone to email. Any ideas? Link to post Share on other sites More sharing options...
Stephen55 Posted January 13, 2016 Share #12 Posted January 13, 2016 I have contacted Leica customer services UK requesting confirmation that the camera should display over as well as under exposure in all lighting conditions. I have also referred them to these posts. So far I have had no response ... Link to post Share on other sites More sharing options...
SamuelF Posted January 13, 2016 Share #13 Posted January 13, 2016 I think the most important problem to address is that the EVF histogram does not reflect the exposure compensation in low light situations. Link to post Share on other sites More sharing options...
Stephen55 Posted January 13, 2016 Share #14 Posted January 13, 2016 Could others please contact Leica directly about this (although I suspect they are already aware)? Link to post Share on other sites More sharing options...

The histogram is the tool of choice. Anyway, how does the camera react when the exposure is set manually? I typically use the histogram, but as others with this problem have pointed out, the histogram only seems to show results based upon what's shown on the LCD monitor (although the DNG/JPEG results do show positive exposure compensation). I find on mine it does display dimming in the negative direction to -3 in good or low light but in the positive direction it does go to +3 in good light but no change to display beyond +1 in low light. The image taken does reflect the over exposure in low light it just doesn't show on the LCD/EVF. I haven't tried good light, and so am uncertain of the +3 behaviour, but thanks for confirming that there's some commonality (for some) to this (low-light) idiosyncrasy. Perhaps, with all of the options (auto/manual ISO, aperture, exposure, plus different metering options, etc.), there's some bug in the FW? I'd hate to think that there's some HW problem here ...

millsart Posted January 14, 2016 Share #16 Posted January 14, 2016 I'm sure the LCD/EVF simply can't gain up any more in lower light levels, at a risk of causing the refresh rate to slow down too far, as such, there is a limit to how bright the scene can be made. Seems nothing to worry about as the camera can increase the brightness to reflect changes in EC in most lighting conditions. Unlikely to really want to shoot +3 EC in dim lighting I would think...

I have been in contact with Leica UK who have been very helpful.They have requested that I don't quote them on this forum, but I do think you are more or less along the right lines in your explanation above.
