jacksbenjamin Posted January 13, 2023 Share #1 Posted January 13, 2023 Advertisement (gone after registration) Hi all, hope everyone is having a beautiful start to their 2023! Love this community and would be very appreciative for any insight on the following. Since the firmware updates of 1.3 and 1.6 I notice that the camera has LiveView issues with Lens Profiles, essentially when you are viewing and scanning various indoor areas (that is where you see this most) vignetting becomes more or less introduced, as if the camera is making real time adjustments to the lens profile that has been input, or if the Lens Profile has been set to auto. NOW - If you turn OFF the lens profile function this all goes away, but of course we want to know what lenses we shot with for our metadata so I don't see lens data off as a great solution for this, I experienced this with my SL2 and then later Leica fixed it, but its quite distracting when shooting with LiveView from back of camera or with the VisoFlex. Anyone else experience this? I filmed the back of the camera while hand-held tilting to show what happens, please excuse the shaky hands but I was filming the back of the M while also holding the iPhone, but you can see the shifts of vignetting as the camera tilts up and down. You can see video here >> https://drive.google.com/file/d/1gF5Z3hJy6mlP3uS6kxKmSYiD3TXWW5Vl/view?usp=sharing Any thoughts greatly appreciated!

Photoworks Posted January 13, 2023 Share #2 Posted January 13, 2023 it looks like an exposure preview adjustment to me. as you tilt up the sealing vignetting appears lighter, but in reality you just moving from the center light source. try again with exposure preview to permanently, and even lighting.

jacksbenjamin Posted January 13, 2023 Author Share #3 Posted January 13, 2023 @Photoworks - thanks for your thoughtful response! I checked exposure preview with it on permanent, at half shutter release, and off — and it still occurs. Then when I turn OFF the lens profiles function, it all goes away. it’s pretty subtle the vignetting — but I do find it distracting so I may need to just live with no lens profiles until next update? 🧐 39 minutes ago, Photoworks said: it looks like an exposure preview adjustment to me. as you tilt up the sealing vignetting appears lighter, but in reality you just moving from the center light source. try again with exposure preview to permanently, and even lighting.

lct Posted January 14, 2023 Share #4 Posted January 14, 2023 Did you set up a user profile for this lens? Quote Link to post Share on other sites More sharing options...
jacksbenjamin Posted January 14, 2023 Author Share #5 Posted January 14, 2023 @lct thanks for you response amigo! I have my own user profile on camera which is active, I have also assigned the lens profile - Summilux 11874 from the look up menu, and also tried with it on auto sensing. in all scenarios it shows this live view vignette changing etc, but when I turn off lens profile it goes away. it’s a mystery as to why it’s happening!

jaapv Posted January 14, 2023 Share #6 Posted January 14, 2023 When you tilt the camera, do you happen to have your finger over the external exposure meter? The camera guesstimates the aperture by this means combined with the actual exposure. If that is incorrect the vignetting compensation will be incorrect.

jacksbenjamin Posted January 14, 2023 Author Share #8 Posted January 14, 2023 @jaapv thanks for your reply! I don’t have the exposure meter covered when doing it. It’s quite a strange phenomenon as to why it’s happening, and @lct - appreciate the recco, I am on 1.6 firmware but it did not solve it so no one else has experienced this? Cheers all 🙏🏽🙏🏽 Quote Link to post Share on other sites More sharing options...

If yes, you may wish to update your user profile now and see what happens Quote Link to post Share on other sites More sharing options...
Photoworks Posted January 14, 2023 Share #10 Posted January 14, 2023 I just tested it with a Leica lens and a non Leica lens. with preview exposure on and holding she button the exposure and other effects don't change on my camera. You must have set something different. Quote Link to post Share on other sites More sharing options...
jacksbenjamin Posted January 14, 2023 Author Share #11 Posted January 14, 2023 @lct thank you! I did try another user profile and did not work sadly. @Photoworks very much appreciate you trying both lenses! I tried a Summilux 35 11874 and a Voigtlander and it happens on both, it’s most notices when scanning a white wall where you can really see the vignette changes. And again it all goes away when Len profiles are turned off. It’s a mystery! Really appreciate everyone’s insights. Will keep digging for the solve… Quote Link to post Share on other sites More sharing options...

jacksbenjamin Posted January 14, 2023 Author Share #13 Posted January 14, 2023 @lctindeed I did! But sadly still no good Quote Link to post Share on other sites More sharing options...
lct Posted January 14, 2023 Share #14 Posted January 14, 2023 You may wish to remove the card and work with the internal memory alone. Does it change anything? Quote Link to post Share on other sites More sharing options...
jacksbenjamin Posted January 14, 2023 Author Share #15 Posted January 14, 2023 Thanks! @lct tried that as well — great idea, but still a bust. It’s certainly most noticeable in indoor areas with lots of white whereas outside it’s pretty subtle. But still there. And of course once I disable lens profiles it’s gone. So strange! Anyhow, you all have been very kind in helping navigate. If you find a solve, awesome, but don’t want to take up too much bandwidth from the community. 🙏🏽 Quote Link to post Share on other sites More sharing options...
lct Posted January 14, 2023 Share #16 Posted January 14, 2023 (edited) Time to ask Leica perhaps. Edited January 14, 2023 by lct Quote Link to post Share on other sites More sharing options...
jacksbenjamin Posted January 14, 2023 Author Share #17 Posted January 14, 2023 @lct in agreement, going to email Kathy at the NJ office to see what’s up… will report back 1 Quote Link to post Share on other sites More sharing options...

I would have thought if lens corrections were being applied in real time that you'd see the opposite... more vignette with profiles disabled. I tried to reproduce this with an uncoded 75 'lux, but despite monkeying with a number of settings... metering modes, enabling and disabling lens detection, rear display vs EVF... nada. The only thing I see when panning from a darker scene over to a bright light is the exposure changing. Quote Link to post Share on other sites More sharing options...

jacksbenjamin Posted January 15, 2023 Author Share #20 Posted January 15, 2023 (edited) @Photoworks indeed correct! Vignetting is def there naturally (which I love), it’s just the pronounced effect changes (real time differences) with the Lens Prof on as I pan and scan which is the mystery. I hope to uncover answers from Kathy at the Leica NJ office this week. Will keep everyone posted! 🙌🏽 Edited January 15, 2023 by jacksbenjamin Quote Link to post Share on other sites More sharing options...
