Leica Q3 43 Exposure Preview Issue

Hello,

Just purchased the Leica Q3 43 and I am noticing that when I half press the shutter button the exposure preview goes wonky. The actual image matches the no shutter button press preview, but when I half press the button the shutter it either goes way too bright or too dark. I see that this was discussed for the Q3 28 a while back but have not seen any recent discussion (like in the last 9 months). The consensus at the time was a firmware issue. What was the resolution? My firmware is 2.05 which I believe is the latest. I have a Q2 that I use extensively and have not seen this issue. In case it's asked I do have the exposure preview set to PASM. 

Thanks in advance for any info.

Well I think I figured it out. The camera was set to iAF mode. When I switched to AFs mode the issue goes away, or at least behaves like my Q2. AFC behaves like iAF.  I assume the issue arises when the camera is locking onto focus, which for AFs is a one and done, but iAF and AFc is always calculating focus. Does this sound right?

Yeah I was about to respond but found you figured it out.

I had exactly same issue, but only when using iAF. At first I thought it were due to the iDR, but later I figured it’s related to iAF.
I just don’t understand why preview has anything to do with focusing. But I just don’t use it anyway.

Thanks for the reply. Some things we may never know 😁

My new Q3 was doing exactly the same thing. I checked the AF mode but it was on AFs . I put it in and out of iAF and back into AFs and the problem was solved !

I have just updated the firmware to 3.00 and the problem has returned. Tried toggling between the AF 's as before but no joy. I then did a full Camera Reset and the problem has gone, for now !

Same issue here, a brand new Q3 43, unfortunately, updated the firmware (My Q3 1.1 does not do that).  It doesn't seem to be consistent; mine seems to do that in AFs only . Clearly a bug, a bad one. It is strange that only a few are complaining; it makes you wonder if anybody is actually paying attention or even using the camera ☹.

It only happens in AFc or iAF. It doesn’t happen in AFs at all.

It’s you or camera or both.

and people do pay attention and do use the camera. They just don’t pander to your opinions.

I borrowed a Q3 43 and couldn’t understand why this was happening, and exposure itself was off, despite using the same settings as my Q3 28. I checked the settings and discovered that I had forgotten to switch off iAF and JPG. Once I I had corrected that and made sure I was shooting RAW only, the problem disappeared.

It’s not an “opinion”, it’s a fact, as far as “me and my camera” goes (attached is a video for your pleasure). As I said it’s not consistent with others findings.

Let me be more clear.

Exposure preview goes dark only in AFc and iAF, it doesn't happen in AFs. It's your problem or your camera problem or both.

The fact you reached conclusion nobody is paying attention or even using the camera, is patronizing. People don't mention it because it doesn't happen to them in AFs mode.

I have both RAW and JPG, and only shoot in AFs. It doesn't happen to me. Latest firmware.

Or maybe it’s the other way around, or do you know of all cases?? Sorry you felt patronized, I was actually trying to help you out, since it’s quite clear that this is a bigger problem than the one you reported on.

just checked indeed AFs is the way to go .

 

[leicaschwartz]

Mine also does it in AFs, and occasionally on AFi.  A friend of mine has a slightly older Q3 43 (firs dealer batch), he has no issues.

In AFs mode everything is fine, but in AFc the image darkens for some reason. This is clearly a bug of the latest firmware, I do not remember such behavior on the previous firmware.

Same Bug here... the preview goes darker, Q3-43 latest firmware.
Always present in AF-C... random in AF-S
I want to use my camera in AF-C... I think I've payed enough for that... correct me if I'm wrong...

Very annoying!

It's not a bug, it's an inherent issue with AF-c in live view.

Look at the aperture in the lens when focusing the AF-s and AF-c, you will notice the difference and you will understand why.

I understand and I see, just let's not accept and pretend that is more a characteristic than an issue for the love of the brand 😉

I never said it's a characteristic.

Do you have other mirrorless camera, such as Nikon Z? Or DSLR camera like Nikon F? Try to use the aperture smaller than f/5.6 with live view, see what happens?

This is not a unique issue to Leica. That's why I said it's an inherent issue.

No no, it was not related to what you said... it was a general statement/joke 😉

By the way... In recent years I was shooting with Canon R5/R6, Nikon Z6II and until 1 month ago with a Z9... actually... never seen this issue before. (and I had 1.8s and 1.2s wide open all the time)
So yes, this issue is quite new to me 😉
