Steve McGarrett Posted July 4, 2018 Share #1 Posted July 4, 2018 (edited) Advertisement (gone after registration) Hi all, I've noticed that the on-camera profiles for R lenses, automatically applied in Lightroom after importing DNGs if the correct lens was selected in the camera menu, often overcorrect vignetting at mid-apertures (f/5.6 to 11), resulting, in slightly brighter far corners. I had to set some vignetting in Effects menu to compensate for this, or even better turn off the on-camera profile before the shot (but then I have no EXIFs, of course, nor other corrections for distortion and/or chromatic aberration). Has someone else noticed that? I'm running v3.0 firmware. Thanks Edited July 4, 2018 by Steve McGarrett Link to post Share on other sites More sharing options...

jaapv Posted July 4, 2018 Share #2 Posted July 4, 2018 That is the problem with automatic in-camera corrections of optical vignetting in general - it is aperture dependent, so it is under- or overdone at all apertures but one. 1 Link to post Share on other sites More sharing options...
Steve McGarrett Posted July 4, 2018 Author Share #3 Posted July 4, 2018 It would be nice to switch it off without losing distortion and LCA correction, but it's not possible... Link to post Share on other sites More sharing options...
jaapv Posted July 4, 2018 Share #4 Posted July 4, 2018 But it is so easy to fix in postprocessing, as is CA. And distortion? Leica lenses have so little... R lenses even less than M lenses, in general. Link to post Share on other sites More sharing options...

R lenses even less than M lenses, in general. That's true, but it's annoying to switch off the profiles and lose all EXIFs info... you need to remember which lens was used then, and manually code it with Lenstagger or similar LR plugins. A simple on-camera menu in which you can choose if activating/deactivating vignetting correction, without losing lens identification, would be nice...

jip Posted July 5, 2018 Share #6 Posted July 5, 2018 They should have made a electromechanical adapter for R lenses, so auto diaphragm would work and aperture data could be accurately saved. Only then I would call Leica R lenses fully compatible with the SL... which Leica now claims... Hasselblad H and Contax 645 lenses ARE fully compatible with the Leica S that way, because it's not simply a 'Dumb' adapter. The lenses retain full autofocus and auto diaphragm etc. Costly adapters, but I'd already have a SL if it was FULLY compatible with my R lenses. 3 Link to post Share on other sites More sharing options...
Steve McGarrett Posted July 5, 2018 Author Share #7 Posted July 5, 2018 (edited) Advertisement (gone after registration) Auto-diaphragm would be nice, but it's not so useful with an EVF, you may stick at working aperture most of the time... The compatibility is already very good in my opinion. This vignetting overcorrection is probably my only complaint with R lenses so far... The S is a different beast, it's a reflex camera, so without auto-diaphragm you'd need to open up the aperture for framing and focusing, and then stopping-down to shot, and then re-open again, every time. Very annoying. Edited July 5, 2018 by Steve McGarrett Link to post Share on other sites More sharing options...
robgo2 Posted July 7, 2018 Share #8 Posted July 7, 2018 I was under the impression that the lens correction profiles are applied in-camera, in which case you could disable the ones applied in post. Is that wrong? Link to post Share on other sites More sharing options...

Is that wrong? Unfortunately not with Lightroom. You can't disable profiles applied on-camera in Lightroom, you can mark and unmark the box in LR, but nothing changes, it just says "profiles for this lens are automatically applied to the DNG".

I only use the LR profiles when I've got the in-camera profiles turned off. The in-camera lens profiles are applied directly to the raw data before it is written to the DNG file, so they cannot be eliminated afterwards in Lightroom. I've not noticed any bright corners since the SL's firmware 2.0 revision was released, some time ago. Prior to that, certain lens profiles had some aberrations that would cause bright corners and even a circular ring to appear. Link to post Share on other sites More sharing options...
jaapv Posted July 18, 2018 Share #12 Posted July 18, 2018 As Godfrey says, you are applying correction upon correction.

Prior to that, certain lens profiles had some aberrations that would cause bright corners and even a circular ring to appear. It's not a problem of correction upon correction, I always keep off LR correction (the ones in the curtain menu Make/Model/Profile). The problem is the on-camera profile, that like you've said can't be eliminated. If I shoot at f/8 with on-camera profiles, I have slightly brighter far corners. It's not terrible by any standards, but it's a bit brighter, so I have to put in some LR vignetting in the Effect tab to compensate.

PetersPhotoChannel Posted April 21, 2022 Share #16 Posted April 21, 2022 LEICA R lenses have no lens corrections programmed in the SL cameras I had the doubt what would happen if I‘d attach a non LEICA Glas with i.e. 80mm to my SL2 with an adapter and would then pick the LEICA R profile for the 80mm Summilux-R f1.4, in order to have at least the right focal length in the EXIF data. Would then my images taken with this third party-lens be treated with the corresponding R-lens profile in my SL2 camera? The answer from LEICA was, that no lens corrections are programmed for LEICA-R lenses in the SL and that I can attach whatever I want and choose a LEICA-R lens Profile and that the image will not be altered in camera. AND they said that the in camera image stabilizer works independently from the chosen focal length. So, if you want to attach a lens with a focal length that is not present among the LEICA-R lens profiles, that would not matter. You can even choose a 21mm focal length and attach a 280mm tele and that the camera would still stabilize the image correctly. It‘s just important to choose any LEICA R or M profile to make the stabilizer work. That information surprised me. What about you . . . ?

sarav Posted April 26, 2022 Share #18 Posted April 26, 2022 but bright corners with r-lenses is still there. Any solution? I switch off lens recognition but every time I swap lenses it turn itself on and I forget to turn it off...it's awful. 1 Link to post Share on other sites More sharing options...
PetersPhotoChannel Posted April 26, 2022 Share #19 Posted April 26, 2022 Hi sarav, that might have to do with the firmware version of your camera. I checked it on my M10-R camera and there the automated lens recognition stays turned off when I choose that option. Link to post Share on other sites More sharing options...
