Giacomo Sardi Posted October 10, 2018 Share #1 Posted October 10, 2018 Advertisement (gone after registration) Hi, i'm wondering if you have the correct exif data lens for the M-lens 6bit coded when used with original leica M-to-L adapter. Have you the Name and focal of the lens in EXIF? I haven't the original adapter, and i don't have this information in EXIF, even i indicate manually the type of the lens.... no value So , when i load the dng file in lightroom i can't correct the distortion and the vignette automatically.... So i'm wondering if the problem was the adapter.... this is an example with dng file: Filename - L1040309.DNG ImageWidth - 720 ImageLength - 480 BitsPerSample - 8 8 8 Compression - 7 (JPG) PhotometricInterpretation - 6 Make - LEICA CAMERA AG Model - LEICA CL StripOffset - 28672 Orientation - Top left SamplesPerPixel - 3 RowsPerStrip - 480 StripByteCount - 74752 XResolution - 72 YResolution - 72 ResolutionUnit - Inch Software - 2.07 DateTime - 2018:10:07 15:06:27 Artist - Copyright - ExifOffset - 2086 ExposureTime - 1/400 seconds FNumber - 0.00 ExposureProgram - Normal program ISOSpeedRatings - 100 ExifVersion - 0230 DateTimeOriginal - 2018:10:07 15:06:27 DateTimeDigitized - 2018:10:07 15:06:27 ComponentsConfiguration - YCbCr ExposureBiasValue - -1.30 MaxApertureValue - F 4.50 MeteringMode - Multi-segment LightSource - Auto Flash - Flash not fired, compulsory flash mode FocalLength - 0.00 mm FlashPixVersion - 0100 ColorSpace - sRGB ExifImageWidth - 6120 ExifImageHeight - 4016 SensingMethod - One-chip color area sensor FileSource - DSC - Digital still camera CustomRendered - Normal process White Balance - Auto DigitalZoomRatio - 0.00/0.00 x FocalLengthIn35mmFilm - 0 mm SceneCaptureType - Standard Contrast - Normal Saturation - Normal Sharpness - Hard Lens Info - 0.00/0.00 0.00/0.00 4.34 4.34 Lens Make - N/A Lens Model - N/A Lens Serial Number - N/A Maker Note (Vendor): - Quote Link to post Share on other sites More sharing options...

Giacomo Sardi Posted October 10, 2018 Author Share #3 Posted October 10, 2018 tnx! ok, so when you import a dng file in lightroom you have the auto-correct-lens-profile function enable with embedded lens profile? p.s. sorry for my english Quote Link to post Share on other sites More sharing options...
lct Posted October 10, 2018 Share #4 Posted October 10, 2018 Sounds logical but i don't use LR sorry. Quote Link to post Share on other sites More sharing options...
ramarren Posted October 10, 2018 Share #5 Posted October 10, 2018 Yes the EXIF data is embedded correctly for all my M and R lenses with the Leica adapters. However, I’ve found that LR often fails to identify the lens and auto-apply its corrections. Which ultimately I don’t find to be a problem anyway because not all the LR lens profiles are perfect.. It does apply the Leica lens code correction delivered in the raw file metadata, however. Quote Link to post Share on other sites More sharing options...

ramarren Posted October 11, 2018 Share #7 Posted October 11, 2018 Advertisement (gone after registration) I believe that the EXIF data will only be added if you use a Leica mount adapter (I use M Adapter L and R Adapter M, stacked, for R lenses) or an adapter that communicates with the camera's six-bit coding system in the case of adapters to Leica M mount. A typical exposure from my library shows the status of the built-in lens profile in the Lens Correction panel, pops up the Information Box when you click the "i" in the lens correction panel, and shows the lens type and other sundry info in the EXIF data panel.
