Unknown lens - leica m8

the metadata in aperture shows my lens info as unknown (i am using 6-bit coded lens), also the aperture is not displaying.
what is wrong??

Try 'Read Metadata from File'.
Beware that it might overwrite any changes you might have made in Develop or Library module, if those changes have not been saved to xmp. So, before reading metadata, it's a good idea to save it first.

Photos look blurry in Aperture (Unknown Lens)

Hello,
I see a strange behaviour in Apple's Aperture (latest version).
When I import new pictures, taken by a Samsung NX1000 and open the pic the first time it looks sharp.
After less than a second Aperture does something and I see the picture changes from sharp to blurry.
When I open the pic in Mac Finder the picture looks great.
Maybe it has something to do that Aperture does not recognize my lens?
I see that the camera model is correct but with "Unknown Lens"
Hope you can help.
- Attached you see a picture in Aperture (left), and the same pic opened from the Finder.
- The picture on the right is much better. How is this possible? I just import the pic without
any editing into Apreture and get the mess.
LEFT > Aperture --- RIGHT > Same pic opened in Finder on Mac, look way better.
Regards,
Marc

Hi Griff W!
What is the relationship between sharpening and un-adjusted Images in Aperture? The article you cite says:
sharpening adjustments applied to the image may seem less apparent than they really are.
The OP specifies that the effect he is seeing precedes any adjustments made. Are you implying that the article you cite includes the sharpening controls in the RAW Fine Tuning adjustment as part of its definition of "sharpening adjustments"? This is important to know. Thanks for your insight.

After loading Lion I cannot open some pictures. I get Unsupported Image Format. It tells me picture was taken with Canon EOS Rebel with unknown lens

After loading Lion I cannot open open some pictures in Aperture. I get Unsupported Image Format, all files even the ones I can open are .JPG. Also it tells me picture was made using Canon EOS Rebel with unknown lens.

You mention that 'most' of your files are DNG. Try
running the effected files through Adobe DNG
converter again and then import your reprocessed
files to Aperture and see if the problem persists.
I had a problem with a batch of D2x files converted
to DNG which had been metadata tagged by
PhotoMechanic (the evil app).
B.T.W. You mention that you had been using Bridge.
Are you getting any of the embedded XMP metadata
coming into Aperture during the import process?
Already tried that multiple times...no luck. I'm wondering though if it might be related to metadata as you suggest. I'm still trying different things to see what happens.
I was able to alleviate the problem on one set of images by painstakingly searching my external drive for the oldest backups I could find - CR2 files from before DNG conversion. I then ran those through DNG Converter and tried importing them again (this time, I embedded NO thumbnail, but I'm not sure if that made the difference - I think it was more likely a fluke in the original conversion that caused the problem). This time, it worked.
Now, the big problem is that I still have a couple hundred images for which I can't seem to locate the original CR2 files. I don't typically keep them after conversion, as I don't have the space for both.

Unknown lens

In past I took photos using unknown lens at that times.
With new version I have noticed the lens is already known to LR,
newly imported photos are listed with lens name.
But previously imported fotos are still listed under
unknown lens
in search by metadata panel.
Is there a way to "tell" LR to update it even for old photos?

EXIF Tag problem / unknown lens

Hi everyone,
I imported a few raw files in lightroom 3.4.1 (mac version, but this is irrelevant), all of them are from Sony cameras and different lenses.
From the command line, exiftool always reports the correct camera model/lens, but lightroom often does not.
From the exiftool documentation, it seems that Sony has a specific EXIF tag for the lens model, called "LensID".
However when LR generates the xmp, it does write some lens information in it, but I cannot understand where it reads from.
For example, I run a sample query on a raw file, which LR correctly identifies, asking all possible lens-related fields:
exiftool -Lens -LensID -LensModel -LensType -LensMake -LensSerialNumber _DSC0350.ARW
Lens ID                         : Carl Zeiss Vario-Sonnar T* DT 16-80mm F3.5-4.5 ZA
Lens Type                     : Carl Zeiss Vario-Sonnar T* DT 16-80mm F3.5-4.5 ZA
and in the corresponding xmp file I have:
<aux:Lens>DT 16-80mm F3.5-4.5 ZA</aux:Lens>
<aux:LensID>46</aux:LensID>
and if I query directly the xmp file (which exiftool can do):
exiftool -Lens -LensID -LensModel -LensType -LensMake -LensSerialNumber _DSC0350.xmp
Lens                            : DT 16-80mm F3.5-4.5 ZA
Lens ID                        : Carl Zeiss Vario-Sonnar T* DT 16-80mm F3.5-4.5 ZA
So, the LR-generated "Lens" field in xmp is a *different* string.
If I repeat the same procedure on some different raw files (from different sony cameras), I get different results: most times the xmp contains no lens field, and LR says "unknown lens", even if the ARW does contain the same information shown above.
If I manually fix the xmp with exiftool and I force LR to reload metadata from files, then I get the lens identified.
Is it possible to fix this situation somehow?

In my opinion, it is not possible to get a reliable lens identification with Sony/Minolta cameras unless you have a lens lookup list which fits your actual lens collection. So that means that you either have to buy lenses which fits the lookup list in your identification tool, or use an identification tool which allows you to modify the lookup list. The latter option excludes using Lightroom for lens identification, as far as I know. I don't know about exiftool.
Old Minolta IDs have been reused by Sony when they released similar lenses, which I guess is acceptable but can result in Sony lenses being recognized as Minolta or vice versa. Even worse is that third party lens makers have released a lot of lenses where they use a more or less random ID from the Minolta lenses.
Here is an example of lenses using ID 25611:
Minolta AF 75-300mm F4.5-5.6
Sigma 70-300mm F4-5.6 DL Macro
Sigma AF 300mm F4 APO Macro
Sigma AF 500mm F4.5 APO
Sigma AF 170-500mm F5-6.3 APO Asph
Tokina AT-X AF 300mm F4
Tokina AT-X AF 400mm F5.6 SD
Tokina AF 730 II 75-300mm F4.5-5.6
Sigma 70-300mm F4-5.6 APO Macro
Sigma AF 500mm F7.2 APO
(And now I just discovered that this list is incomplete, since the exiftool link posted by ixtab alos lists an ID 25611 Sigma 800 mm which is not in my list.)
To some extent, the correct lens can be picked from the list if combining ID, max. aperture and focal length from the EXIF. If ID is 25611, max. aperture is 4.5, and focal length is 500, it can only be a Sigma AF 500mm F4.5 APO.
But if ID is 25611, max. aperture is 5.6, and focal length is 300, there are actually 4-5 different lenses which match. With a little luck you only own one of those lenses and can give that lens the highest priority in the lookup list. That is why it is so important to be able to modify the lookup list.
I use a command line tool called alphalensinfo which does just that: Uses the combination of ID, max. aperture and focal length and allows you to modify the lookup list. The information is written into an .xmp file which is imported with the image into Lightroom.
I know that exiftool can do something similar, as stated earlier in the thread, but I have no experience with using it for this purpose (even though I actually do use exiftool in the same batch process to rectify the Orientation tag of the photos).

Unknown lens (& also known lens)

I had taken some photos from my Canon EOS 5D Mark II, using the the 24-105mm/f4.0L IS USM lens.
But on importing them into Lightroom 2.3, about 25-30% of the photos show "Unknown Lens" under metadata, whereas 70-75% of them correctly show "24-105mm f/4L IS USM"
Is it some standard/ known issue of Lightroom? Is there anyway to fix those few hundred photos so that they show the correct lens info?
Any tips/ advice greatly appreciated. Thx.

I don't recall any reports of this nature, so it's certainly not standard.
Lightroom gets the info from the Exif embedded into the original file by the camera. If some are showing the lens as Unknown then it's very likely due to the camera lens combination. Establishing what that might be will require some detective work at your end. For example, was the lens attached to the camera via a non Canon extender? Was the lens properly attached? Have you tried cleaning the contacts on the lens and camera?
Fixing the images you've already shot can be achieved in at least two ways. The first involves editing the actual Exif in each file using an application called ExifTool http://www.sno.phy.queensu.ca/~phil/exiftool/ Unfortunately, I can't offer any guidance on how you would go about it with this application. The second method involves saving the metadata for each file as an XMP sidecar (Save metadata to file in Lr Metadata menu) then using a text editor to search and replace ** the bad lens info. Most text editors can run this type of process as a batch, so it doesn't take long. When the files are fixed you would then use the Read metadata from file menu option to import the updated Exif.
Search for <aux:Lens>Unknown</aux:Lens>
Replace with <aux:Lens>EF24-105mm f/4L IS USM</aux:Lens>
Edit: the following link will take you to a GUI front end for ExfTool http://freeweb.siol.net/hrastni3/ However, I don't no whether it allows you to edit the lens type

Thanks Tony,
Yes the supplied profile works - in my test shots it corrects distortion and vignetting nicely - but it is a pain to have to pick the proffile by hand for each shot.
My real issue is Lightroom not correctly identifying the lens and listing it as "Unknown" in the meta data. Was hoping there was a way to teach lightroom to recognize it - or a config file to hack to make it recognize the lens.
For testing puposes I changed the raw format of my Pentax from DNG to PEF but got the saame result.
Anyone else have ideas?

Unknown camera and unknown lens

Hello,
For some reason today, Aperture is not recognizing my camera or lens when I import images from my memory card. There is no photo or exif metadata being reported by Aperture for the photo's imported today. Photo's that were imported last Monday have the correct photo and exif metadata.
Photo's were taken with a Nikon D7000 and 35mm f1.8 DX lens. I used ViewNX2 to grab the metadata from one of the photo's on the memory card and the camera make and lens information are correct. When I open the file in Preview.app I can see the following metadata in the "Exif" tab:

I noticed the Lens ID in the Aperture metadata shows -2,147,483,648. That seems odd to me. However, the Lens Model, and Lens Info appear correct. I checked the Lens ID number with Preview for one of the photo's in Aperture where the metadata appears correctly and it is the same -2,147,483,648 number. So, I surmise my camera likely does not use this field. From the "TIFF" tab I have the following metadata:

The Make (Nikon Corporation) and Model (Nikon D7000) appear correctly. There is a "Nikon" tab as well which reports:

ISO Setting: 0, 400
Lens Type: 6

None of this metadata makes it into Aperture for any of the photo's imported today even though the metadata is being viewed with Preview directly from the corresponding JPG files imported into the Aperture library.
Other information that may or may not be relevant:
I reinstalled Aperture a little over a week ago because the names of the adjustment bricks suddenly changed to names that all started with "DG..."
Adobe Flash suddenly stopped working when viewing an online video today and I could not view a flash video from any website after that. I uninstalled and reinstalled Flash.
OS X 10.8.2 supplemental update was installed today after I noticed this problem (from 10.8.2).
Any idea's?
Steve

Update.
I trashed the preferences and moved the ~/Library/Application Support/Aperture folder. No change.
I created a new library, imported a photo and then could not see the project. Quit and Aperture will not open the library but I can open it with iPhoto. Sure enough, the imported photo does not have the photo or exif metadata. However, if I create a duplicate of the exact same photo from the master directory in the library and import it again using iPhoto, the metadata appears.
So, definitely an Aperture issue. Will try another reinstall.

Pentax K3 jpeg unknown lens

In addition to there being no Apple support yet for RAW files from the Pentax K3, there is even a problem with jpeg. With all lenses, Aperture reports "Unkown Lens" in the EXIF for jpeg files. Pentax Digital Camera Utility 5 reports the correct lens. Has anybody else seen this?

I'd send feedback to Apple with the exact name of your camera model and the specifics of the lens. The exif tags for some lenses are ambigious, but Pentax software will naturally assume that you are using a Pentax lens with your Pentax camera.
The feedback (use this form Apple - Aperture - Feedback) has reportedly worked in previous cases, and the developer team has fixed the lens problem, see for example this post by Libertin:
Re: Aperture doesn't recognize my lens anymore

Aperture 3 - Lens unknown in RAW metadata

In Aperture 3 my lens information will only display data for one of my three lens. My 18-55mm kit lens for my Canon T2i is the only lens that shows up. My Zeiss 28mm just displays "Unknown (33) 28mm" and my Tokina 11-16mm displays "Unknown (160) 11-16mm." Does anyone know why this might be happening in Aperture?

With my Tokina 11-16 mm I had the same problem in JPEG metadata. I found a solution and wrote a little app: http://touristathome.tumblr.com/post/24342878728/unknown-lens-aperture

Lightroom not reading correct data for Lens and Camera Serial Number

Hi you all.
Recently got Lightroom, and I'm so impressed - I never imagined image organizing and adjustment could be this easy and at the same time very advanced.
I have a problem, however. Lightroom (and Adobe Bridge, too) does not correctly read the EXIF data of Lens type and Camera Serial Number.
The first ~50 images I took and imported turned out correctly and displayed my serial number and lens (18-55 mm Canon) inside Lightroom.
But now, whenever I import photos into Lightroom or view them with Bridge, they all display "Unknown Lens" and "Unknown Camera Serial Number".
At first I thought that maybe the camera didn't correctly record this data on to the photos anymore for some reason, but a comparison using EXIFToolGUI shows that the metadata is EXACTLY the same as in the photos that display this info in Lightroom correctly.
I have not done any changes to either my camera (Canon EOS-350D / Digitial Rebel XT) or lens (the kit lens, 18-55 mm Canon).
It seems that for some reason, Lightroom has stopped reading these two fields of metadata - all the other fields, such as aperture and shutter speed, all display correctly.
I also tried to reimport the photos into Lightroom, but it didn't help. Neither did "Synchronize Folder" -> "Scan for metadata updates".
What should I do? I'd like my lens information do display correctly, as I'll buy a new lens soon.
I have attached one of the photos that Lightroom doesn't read the data correctly from. Try importing it into your Lightroom, and see if how the info displays.
Thanks in advance.

Are these jpgs or RAW? I have only edited metadata on jpgs.
It looks like Vista's import stripped out all the makernotes. I didn't look at your file but that seems to be what happened. Be warned, Photoshop CS2 also strips out makernotes!
Now how to fix the problem. If you want to edit the metadata on files already loaded into LR, you need to write out your metadata to the files first, then edit the metadata, then read the new metadata into LR. This is scarey for me, so I always make sure my backup is up to date on the images first.
What to do... You probably can't put back all of the makernotes, so what to do to get the lens information in. I don't know if putting back in the makernote LensType would trigger LR to reconsider its lens information. I don't know. If it had a real lens name, my guess would be no because it would have an XMP::Lens field which would override. But maybe unknown lens doesn't have this field and it would re-read the makernotes.
The other solution is to forget about makernotes for these images and put the exact text you want into XMP::Lens. I think that's the "easy" way.
In either case, you will have to become familiar with exiftoolGUI or exiftool itself. I use the command line exiftool but it looks like you can edit multiple files with exiftoolGUI. Select your files, click the edit thingy (^) under XMP, choose various, and there is lens. Put in the text you want.
I would do this with one file first. If the lens shows up after you read the new metadata into LR, you know you have it right.
Note, exiftool can write backup files for each file. This makes too much of a mess for me. I prefer to copy the directory first (I have copies anyway, I just have to make sure the backups are up to date).
Good luck! I'm struggling with a similar situation where the same lens used by two different cameras is coming out with a different name. I need to go back and "fix" the names in the images already imported, and then develop my procedure for setting a single unique name before I load new images into LR. Not too much of a problem because I'm loading in GPS information anyway... What's another call to exiftool...

Lens data from Exif

This is a question that was raised in the Lightroom Forum, but I think it might fit better in here. In Lightroom there is an option to sort images with respect to lens used, a very neat function, but when using raw files from Minolta (.mrw) or DNG's converted from these, no lens data is provided. The only information in there is "Unknown lens". Can this be fixed?

It may work this way with Pentax PEF files but unfortunately doesn't with Minolta MRW or Sony ARW files. Of course, Minolta AF (and now Sony Alpha) lenses do report their identities to the camera, and the camera does write this info into the EXIF data but it ends up as an obscure lens ID in the Minolta (or Sony) Maker Notes where most 3rd-party software (including Adobe's) cannot (or would not) access it.

This is not true! Adobe XMP won't read the Maker Notes sections but it does preserve them. When I convert an MRW file to DNG (with Adobe DNG Converter) and then create a TIFF or JPEG file from the DNG (with Camera Raw) then the Minolta Maker Notes will still be present in the final TIFF or JPEG file (and of course in the DNG file, too).

Sigma lenses don't have Minolta/Sony lens IDs but just random numbers. Kindly ignore what Sigma lenses do. And please don't bother which lens 'was really used.' Just provide us with the lens ID found in the EXIF Minolta/Sony Maker Notes data. Please!
By the way, is there a way to access the Minolta Maker Note LensID tag (or any tag) in the EXIF data through the JavaScript API? If not then please add one!
Currently, I enter the names of the Minolta/Sony lenses manually into the metadata. I customized my File Info Panel 'Camera Data 1' so I can enter the data there in a fairly comfortable way. This is not too hard to do because usually I am using no more than two or three different lenses per assignment usually. This way, the lens names go into the exif/1.0/aux tag named 'Lens.' Unfortunatey, due to a bug in Bridge or in XMP, raw files and DNG files won't accept changes in this and a few more tags; only TIFF and JPEG files will. Instead, the change will get stored in Bridge's cache only. So I wrote a Bridge script to manipulate the XMP sidecar files' contents directly, to 'burn' the changes from the volatile cache permanently into the disk files' metadata.
All this would become *much* easier when 1) we had access to the lens ID in the Minolta (or Sony) Maker Notes and 2) someone would eventually care about fixing that $#!+ metadata bug in Bridge (or XMP) which was already there in Bridge 1.0 and still is around in Bridge 2.1.

Leica Noctilux-M 1:1/50 and LR 4.3

I cannot find my lens Leica Noctilux-M 1:1/50 in the list regarding lens correction in LR 4.3. LR suggests the 0.95 version of the lens. Will that do or is it possible to add my lens to the list?

Oliver,
Please check on the desktop if there is any new folder with the name Adobe has been created or not.
If yes, you could try to manually launch the setup file for Lightroom and install it.
Hope that works

Adding a lens to metadata

I frequently use an old Nikkor 500mm CAT lens with my D100 Nikon. Since the CAT 500 is completely manual - even the f stop is fixed at f/8 - all the pictures taken with this lens appear as "unknown lens" in the metadata.
Is there a way to manually add to the list the 500mm lens? It would be easy to select the pictures shot with this lens and make the assignment manually.
Thank you.

I asked 1st question because, if you were familiar with ExifTool, then I would give just commands needed. This would be the faster way to help you -but, as you've noticed, quite complicated.
2nd question was for case, your answer to 1st question would be "no" and I could maybe help you anyway -which is the case here.
First, please visit my homepage http://freeweb.siol.net/hrastni3/ -and download ExifToolGUI (wouldn't hurt if you also read what's written there).
In short: using ExifToolGUI, you can manually define lens for all selected image files (see menu "Modify>Nikon Makernotes").
I don't have example of image file taken with such lens (to see all "unknown" data inside file). Because of that, all selected files (where Exif:Make=NIKON) will be updated -so be carefull which files you select/edit.
Even further: I don't own Nikon camera nor Nikon software -so after modifying image file with ExifToolGUI, tryout opening image with Nikon software.
For Lightroom: after modified image file is imported, all relevant lens data appear inside Lightroom as expected.
I hope that is of some help to you.
Greetings,
Bogdan
PS: It was confirmed, that ExifToolGUI runs on Vista too.

Aperture 3.3 search by lens no longer works.

I can search by focal length, but putting say "lens includes 70mm" in the EXIF search (yes, it's ticked) just returns a blank sheet, despite the album having many shots taken with my 70mm prime. Are other people seeing this?

The "lens" exif tag describes the "make" of the lens. Do you see the lens meta data tag in the Metadata section of the inspector panel, when you add the "lens" tag to one of the metadata presets? For me the "lens" metadata tag is grayed out for all cameras, also in the "Info" tab of the Library Inspector. So I cannot search for the "lens", only for the "focal length" used for the image.
This "unknown lens" problem has been around since Aperture "3.2"; see the links to the right of this post.
As a work-around, search for the "focal length" or create your own custom metadata "mylens" tag and set it on import.
