Lenses in Lightroom

What metadata field does Lightroom use for lens information and how is it formatted? I have a Panasonic G1 and the lenses don't show up in Lightroom. I do see the lens information in text in the Maker section in a field called LensType. As far as I can tell I can't use this field in Lightroom.
The Maker section of EXIF can include Lens, LensModel, and LensType. And maybe there are two LensType fields
(they aren't identified by name but by a number
[MakerNotes] 0x0016 Lens Type
[MakerNotes] 0x0095 Lens Type )
To make matters worse, some fields/cameras seem to identify the lenses by some number that the varous manufacturers don't agree on.
I'm unlikely to take the trouble to edit the metadata outside of Lightroom for every single picture I take, but I never did understand why Adobe didn't let us use our choice of metadata rather than deciding for us what we want. I have free viewers/editors that will allow me to do so, so I know it can't be THAT difficult a project. Of course it does get complicated by the fact that the same data seems to get duplicated all over the metatada, with often the same stuff in EXIF, IPTC, and XMP, so when you edit a field that is duplicated it maybe problematic to know where all to change it.
The lens situation seems to be almost the morass that date time is!

It was a question. "lens" is not the kind of word that works in searches. I tried it on the old forum and didn't get anything interesting. I searched this one just now and search is the first thing I've seen that I like better than the old forum. So after spending hours reading threads here and doing searches elsewhere, I actually found the answer elsewhere, although I did find it, written a little obscurely, in a thread here after I found it elsewhere.
This is not a GOOD answer because it requires me to rewrite the metadata of every single image file, preferably before I load it into Lightroom.
What I have discovered is Lightroom does read text in the Lens field of the XMP section of the metadata. So in my case, I have to copy the Maker Notes field LensType into this field:
exiftool -overwrite_original "-xmp:lens<${LensType}" *.jpg
What seems to be implied is it reads Canon and Nikon data and translates it into text to put in the Lens field in XMP, but I'm not sure about that. People with other kinds of cameras are out of luck with Lightroom? I'm not sure this is as bad as or worse than the Lightroom date/time fiasco.
I sure would like to have control over metadata in Lightroom -- and the ability to do searches and sorts on all fields.

Lens Lists in Lens Correction Lightroom 5 in Mac

I have a long list of lenses in Lightroom 5 on my PC but with the Mac there is very limited list for Nikon. None of my lenses appear in this on MacSame version. Can I download an updated list into the menu?

Hi Butch07179198,
You could try removing the Preferences File/s. Look here for instructions: http://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-41.html
If that does not help, try removing the .lrdata file from your catalog folder and rebuild previews.
Hope that Helps!

I have Lightroom 1.4.1 and I just started shooting the Nikon D700. I cannot get Lightroom to read my new raw files, help...

I have Lightroom 1.4.1 and I just started shooting the Nikon D700. I cannot get Lightroom to read my new raw files, help... Is there a plug in or update I can get? I can't afford new software after new camera and new lense!

Lightroom 1.4.1 does not support native (NEF) files from the D700 because the camera didn't even exist when it was released. To get support you have two options: upgrade to Lr 2.x (paid for upgrade) or convert your NEF files to DNG.
DNG converter 5.4 can be downloaded from http://www.adobe.com/downloads/ (see right hand side of page)

Lens correction for Hasselblad V series lenses

Lightroom does not provide lens correction for Hasselbald V series lenses, e.g. Carl Zeiss Planar 2,8/80. Hasselblad Phocus program does but Lightroom ignores Phocus metadata in FFF files imports. Is there any posssibility to achieve lens correction for these lenses in Lightroom? Thanks a lot in advance for help.

Here's a list of the currently supported lenses: http://helpx.adobe.com/x-productkb/multi/lens-profile-support-lightroom-4.html
If your lenses aren't supported, you can check the Lens Profile Downloader to see if anyone else has created a profile, or you can create your own using the Lens Profile Creator. You'll find the downloads for those here: http://www.adobe.com/uk/products/photoshop/extend.displayTab2.html#resources

Lens profile for Nikon 12-24mm

I have Lightroom 3.6, which supposedly has a lens profile for the Nikon 12-24mm, but it doesn't show up on the list of available lenses within Lightroom.
How would I find and import that lens profile?

It shows up in my version of LR 3.2 (click image below) so should definitely be available in 3.6. It's listed near the bottom of the first section. Is that the lens you mean?

Lightroom 4.1 won't recognize my supported Nikon camera and lenses under "Lens Corrections"?

Develop Module-Under Lens Corrections, Enable Profile Corrections, Lightroom 4.1 won't auto recognize my Nikon D5000 camera and lenses even though they ARE supported. When I manually choose Nikon in this widow, I can only get 8 of the multitude of supported Nikon lenses to show in the drop down. Of these 8 lenses, none match any of my lenses. How do I fix this? I would like to be able to click the check box for "Enable Profile Corrections" and have it auto recognize my camera and lens.
Here is my history:
I shoot in RAW
This is a new install of Lightroom 4.1 on a new computer with all updates installed.
I'm running Win 7 64bit
I previously used Lightroom 3 on a different computer and it worked great with Lightroom 3
I'm a REALTOR that uses Lightroom to edit my photos, not a pro. So, please give answers that a non-pro can understand. I am really hoping there is some simple answer to my problem.
I did search the help file first and couldn't find an answer.
Thank you in advance for the help!!

OMG... I'm such a nit-wit!! I switched the setting in my camera to try something and forgot to swith it back!
I've been digging through this for more that an hour and never bothered to check the file setting.
Thanks for the suggestion!

Why all the micro4/3 (Panasonic and Olympus) lenses are missing in Lightroom lens corrections?

Is there a reason why all the micro4/3 lenses (panasonic, Leica and Olympus) are missing as lens corrections in all Lightroom versions?

They are not missing.
Within the last year or two many cameras do their own lens corrections before writing the JPG or even displaying the image on the back of the camera or in the electronic view finder, so Adobe does the same thing: the lens profiles are built into the camera raw engine and always applied. It’s confusing because cameras didn’t used to do this and Adobe didn’t used to do this, so we have the situation of older cameras having lens profiles you had to select from the dropdown lists, while newer cameras don’t require this. Of course removable-lens cameras still have this situation, but many/most recent P&S cameras have built-in lens corrections.
The Camera Raw plug-in for Photoshop actually indicates when a built-in profile is being used, but LR does not, yet.

After the update to Lightroom 5.7, the profile of my lenses have disappeared in the camera calibration, how can I import them again because I gave you mine Extra gespeicher. I'm working on a PC.

Can we see a screenshot that includes the filename you're viewing with its extension and the camera Make list?
What is almost always the case when someone says they are missing most of their lens profiles is that their current image is not a raw file. It doesn't matter whether you shoot raw, it matters what the current images is. Maybe it is an exported JPG or a Edit-In-whatever result file that's a TIF or PSD or JPG.
Here are examples of the screenshot that I'm asking for:
Raw files show 24 items in the Make list:
While non-raw files have only 9 items + None in the Make list:

Lightroom Does Not Detect Third Party Lenses Correctly

Adobe really needs to detect third party lenses better...
Here are examples.
example A) Tamron 150-600 VC for Canon.
In EXIF under Camera section, under ??? (Uknown category) lens is correctly identified by the Camera as Tamron SP 150-600mm F 5-6.3 Di VC USD A011.
Under Manufacturer Notes under lens name Camera has it listed as Canon EF 90-300mm F4.5-5.6 USM, that is wrong.
When lightroom imports the pictures it list the lens as Tamron 150-600, that is correct, but it will NOT apply Tamron profile, it requires to be manually selected.
Example B) Sigma 85mm 1.4 for Canon
In EXIF under Camera section, under ??? (Uknown category) lens is identified as just 85mm.
Under Manufacturer Notes under lens name Camera has it listed as Sigma 85mm F1.4 EX DG HSM, that is correct.
When lightroom imports the pictures it list the lens as 85mm, that is incorrect.
Example C) AF Nikkor 85mm F1.4D IF
In EXIF under Camera section, Manufacturer Notes Lens is identified as just 85mm 1.4.
Under Manufacturer Notes under Used lens name Camera has it listed as AF Nikkor 85mm F1.4D IF, that is correct.
When lightroom imports the pictures it list the lens as 85mm 1.4, that is incorrect.
Just 3 examples, I could post 1-2 dozens more.
Adobe nees to improve the import module to check for the lens name in correct fields depending on Camera and Lens manufacture.

Yes, it's annoying isn't it!
I've created a preset to apply the lens correction to the Tamron 150-600 lens. It's easy enough if all the shoot is with that lens, if not, you have to filter the images by lens, then apply it!
As you say, the overlay information correctly says it's the Tamron 150-600 lens, the profile is present, but it won't automatically apply it. Photoshop 2014 CC is the same.

Lightroom 3 doesn't recognise Nikon Lenses, until you tell it Nikon is Manufacturer

Does anyone know why / if there is a fix for this problem. I shoot a Nikon D3S/D3X. Lightroom won't recognise my lenses in the Lens Correction area of Develop. It only recognises them after I put in Nikon as the manufacturer.
Surely the Lightroom software is clever enough to recognise Nikon cameras?
For info am running the 64bit version of Lightroom on a Windows 7 64 bit system.

Oh, it's plenty clever. The problem is that Nikon is also very clever, and cleverness sometimes ends up creating problems.
The fundamental problem is that not all vendors place metadata like the make in the expected places in the image file, so Lr has to resort to many tricks for getting this information reliably. If it cannot reliably get the info, it opts to not guess, as this would be much worse behaviour.
I suspect the "maker notes" metadata in the files made by this camera body aren't quite expected, so once you confirm it is a Nikon, then it can figure out the rest. You can confirm this by supplying an example image by yousendit and others can inspect the metadata to see how it is being stored.
One workaround is to massage these files with a metadata tool to edit the make information into the expected locations prior to importing.
You may also want to raise this with Adobe support, as they might be able to tweak the cleverness to take into consideration Nikon's cleverness.

LightRoom Lens Correction ... huge list (of some of which I have never heard!), but still no mention of Zuiko (Olympus) lenses in the drop-down, even in my 4th update: version 5.6. Anyone know why Olympus has been ostracised in this application?

I am now using a new Nikon, but I still have thousands of images captured with my (very good) Olympus E500, but still frustrated that its lenses do not appear in the drop-down list in the lens correction module ... not even in the latest update, version 5.6

What camera? Is it a mirrorless? Most of those have lens profiles that are built-in and always on so there’s nothing in the list.

Which OS?
Have you made any recent changes to your machine?
Which Lr version?
Did it work with this camera before?
Did you use Nikon software to get your images onto your computer before trying to import into Lr?
How are you importing? Camera to computer? Or via a card reader?
I don't think I've ever seen an example of the lens in use making the difference between a Raw file being imported or not.

Lightroom features/bug fixes I would like to see in next version

I love the Adobe Lightroom Application. It is very intiutive and out of the different RAW processing programs I've tried, it is the only one that has most of the features I need and has the least amount of complications. However, I think there are still places to improve upon:
* Decouple raw processor from the monolithic software executable so that updates to the RAW camera component to add new cameras can be made without requiring huge downloads or reinstallation of a new software program but simply updating a few DLLs and files.
* Improve performance of the Develop panel. It is extremely slow on my laptop running 32bit Windows 7 and 3GB of RAM with dual core processor (pre-Core duo). 8 to 10 seconds for the "loading" message to disappear per image no matter how often I have loaded or edited the image. No caching is being done at all.
* On my higher powered Desktop (Quad Core2 processor/4GB RAM,Windows 7), Adobe Lightroom frequently will start behaving strangely after only a few hours of running. It seems like it is leaking resources or something because eventually functionality will start failing. Specifically, right clicking on images will no longer bring up menus for example. If i shutdown and restart the application, the problem goes away.
* Photoshop-like healing brush. Many times I want to "brush" over areas of image defects but the only choice in Lightroom is the healing tool which always creates a circle and does not allow "brushing". This only works if the defect is a spot and not an irregular area.
* Adjustment with Arbitrary Mask tool. Bibble 5 has this nice concept where you can mask out a section of an image and then apply adjustments to it without affecting the rest of the image. You simply draw a mask and then you can apply adjustments to it. The only option in Lightroom is to select the "Mask" option but that leaves the decision of where exactly you want to mask to Lightroom which only uses edge contrast to determine masking area.
* I'd like a way to tell Lightroom to update the metadata (write out) on all images that are out of sync. Right now the write metadata function will write out metadata to all files whether or not it is required. This means that it is inpractical to try to update your entire catalog as tens of thousands of files will be written to and not just those that are out of sync. This is very important as a way to preserve editing metadata in case of loss of the Lightroom catalog.
* Option to write import metadata to imported files. For example, I have an import metadata for copyright and keywords and I want the imported JPG or DNG files to permanently have this metadata so that even if individual files are copied my copyright and other metadata are preserved with it.
* Option to append text labels to automatically generated import destination folder names. So for example, I can still import into date based directories but append a description to help me remember what the folder contains when I'm later browsing it. Right now it is either/or. You can either choose the name of the import folder destination OR you can have the software generate one for you.
* A google-type search box at the top of the library panel so that ad-hoc searches can be done without having to fool around with the filters. Everybody is used to a single search box for simple textual searches.
* some way to filter images by whether they have been exported previously or not
* Please support lens and shooting information for Sony DSLRs in both JPG and RAW files. Also support 3rd party lenses on Sony DSLRs without assigning the wrong Minolta lenses to them. I want to be able to see both Lens name, max aperture, focusing distance (if available) etc...
* Some way to edit the Shooting lens information to support lenses which are not known to Lightroom, and if suggestion above won't be implemented, some way for the user to edit the lens id --> mapping table so that I can properly map my own 3rd party lenses.
* Facial recognition/tagging option. Some way to have Lightroom apply people tags after I have tagged representative images. Handle multiple people in a scene.
* Automatic (batch) export of images on schedule. I would like a way to configure Lightroom to automatically generate particular export configuration of all my images in a catalog (or some defined subset) such that new files or files that have been edited since last export are automatically exported on a schedule even if Lightroom is not running. Perhaps a Lightroom batch service. This is so that I can always have up to date processed versions of my images for use in my media center display. I would like to configure the Lightroom batch service to run weekly at say 2am every day, run a particular export function and export all new or modified images to a network share accessible by the media center. That way, I can always have access to cropped and edit images without manually doing exports all the time or having to remember which files I've edited and then export them. Also by doing this at off hours it would not slow down my computer while I'm using it.
* Better profiles for Sony DSLRs and support for their picture styles the same way that Canon and Nikon camera are supported.
* Teethering support for Sony DSLRs that have this feature
* Support for parametric plugins -- Plugins that do not require the image to be exported before running.
* Simple support for "picture frames" when exporting. Some way to apply a frame to an image as part of export with a dozen or so frames included and a way for 3rd parties to create more.
* A better way to safely share catalogs or pictures between multiple computers/users in a networked environment.

Did these come to you all at once, or have you been saving them up for a while?
Anyway, Adobe *should* be able to handle long lists of FR, but another option is to break them up and submit them for voting on the new FR/Idea site that will shortly replace this one: (It was really hot for a while, but has cooled down lately...)

They are already decoupled - you can update ACR independently for new camera support, however it's released at about the same frequency as Lightroom itself, so that doesn't help much. Perhaps this should be reworded: "Provide more timely ACR updates..."

I've been complaining about this for a long time - ACR cache is worthless for me too - if dev image not in RAM cache, takes same amount of time to render whether in ACR disk cache or not. Some say ACR cache speeds things up for them - perhaps you need to *believe*...
PS - After new motherboard upgrade, this went from 15 seconds to 3 seconds average.

Yep - Lightroom still has some leaks - gotta restart it from time to time...

RC Importer supports this - its an import plugin that bypasses the import dialog box - not for everyone...

Maybe the seeds of a good idea here, but may be worth some refinement/clarification - what would be searched? Would special syntax be supported? Personally, I mostly hate all 1-box search fields, because one never knows what's being searched and how, e.g. does it search the whole catalog?, is it case sensitive? On the other hand, I get the convenience factor... - I think if accompanied by help and/or the ability to pop up a dialog box for refinement or options, this might make a nice addition. Along these lines, I sometimes think a quick-smart-collection would be nice too - for when one wants to search 2 text fields, instead of just one. I keep a temporary smart collection just for this purpose, but still...
HopeSpringsEternal2008 wrote:

Change detecting export plugins have mostly solved this for me (and publishing for some folks), although adding export info (and metadata change info) to catalog for searching / sorting still sounds like a good idea to me...

Yes, better export management would be welcome. Export Manager might help you (if you have multiple export destinations to update), but its not a panacea... Many of us ultimately "consume" our photos outside Lightroom, having the consumption copies kept up to date more fluidly would be good. Using change detecting export plugins (along with export-manager) and/or publishing helps..

Yep - much room for plugins to get better integrated with Lightroom proper, to participate in image enhancement, as well as other things...

That would be nice. Although support for 3rd parties to add frames *upon export* already exists (export filter plugin + export post-process actions), as well as adding text overlays and such. But since its not built into Lightroom, one has to find them and configure them... And there is no good way to preview them in Lightroom... I think this would go nicely with the previous request - ability to feed image data to plugins for preview in Lightroom. Even if these updates were not built-into the dev module - i.e. weren't kept updated automatically whilst editing - just being able to click a 'see final' button or have it rolled into the build-previews function, so one could have post-process imaging plugins (with preview before export) - might be a nice compromise until true imaging plugins (that fit into dev pipeline) are supported.
The end - for now...

Automatic removal of colour fringing of Panasonic lenses on Olympus body (micro 43) possible?

Hi,
Last week I sold my Panasonic GH2 and bought an Olympus OM-D E-M5. My 14-45 Panasonic lens shows some nasty purple colour fringing with the OM-D (not your ordinary green-purple chromatic aberration, but purple fringing on both sides of highly exposed items, such as steel wheel covers). This I never(!!) saw with the GH2. Fortunately I can correct this in Lightroom. I go (in Develope module) to lenscorrections - colour - remove edge (purple). This works really well, and I know I can synchronise all affected images. But I would like to have this done automatically, just as Lightroom automatically removes all colour faults when using micro four-thirds Panasonic lenses with a micro four-thirds Panasonic body. This is done through special data supplied by Panasonic which are read and implemented by Lightroom (I believe).
Unfortunately this doesn't work when using a Panasonic lens on an Olympus body, which is my reason for this question. I can make my own profile using Adobe Profile Creator to automatically remove chromatic abberations. Reading the tutorial I get the impressions these profiles only remove normal chrom. aberration, not the special purple colour fringing I am talking about. So: is there any way to automate this fringing, or do I have to work on all affected images in Lightroom using the technique I described?
Thanks a lot for your help!
Willem

Before you do all the work creating a profile, why not create a develop preset?
Then you can apply this preset on import to all images taken with this lens and camera.

Lightroom and Sony A700 Raw (ARW) Files

I shot all pictures in ARW format. A number of the shots are at mid to high level ISO numbers. The shots above 400ISO are extremely noisy(both cloro and luminance)When I use the SOny supplied software
the same pictures noise level is significantly reduced. I have read on several other forums that ACR in lightroom is "messing up" the ARW files. This appears to be true. I use lightroom then CS3 to process my shots. The use of the Sony softweare complicates my workflow but at this point I am forced to do this. Is there any relief in site for this concern. Really want to combine everything into one system. By the way CS3 Bridge is not much better.
Any assistance would be greatly appreciated.

I have your lighting right here, JM.
It's quite clear you know nothing about shooting African Cichlids, the most colorful freshwater fish in the world.
These fish are "mbuna", they live in rocks, caves, and along rock faces and ledges. They are used to living many meters deep so the best fish always take up territory towards the bottom of the tank where the best structures are, where the light is most dim.
In this 120 gallon tank is well over 500 pounds of structure which consumes most of the space in the tank.
In many of the photos you will notice rock structures around the fish as the tank consists of a hundred or so ledges and caves.
African Cichlids are the smartest fish in the world and they even learn who is who...they are not ordinary fish.
No matter how much light you throw on African Cichlids it usually does not cure the problem since they spend most of there time peeking from, and hanging under structures. Shadows and dark areas are cast throughout the tanks due to the structures.
Not to mention you must use the lighting already available in every public tank in the business, not to mention fish vendors usually cannot add lighting to their tanks either.
That leads us to use high ISO when we must.
Here are a few Sony A700 test shots made with 3 custom temp 4 ft 40 watt tubes in a deep 120 gallon tank.

Here are a few old shots of mine when I used my custom built and designed setup w/6 custom temp 40 watt tubes made to fit a standard 55. Notice structure galore...it's like an urban housing complex in the mbuna tanks. I can shoot fish with a good pNs setup fairly well with this amount of light. Not many people anywhere get this amount of light on their tank, trust me.

I shot Minolta, and then Konica Minolta, and now Sony has bought KM, so Sony is the one making the bodies for our glass now.
Many of us will not give up image stabilized primes (body SSS) so we stay here. All lenses gain 2-3 stops on the Sony...A700 has top notch DR and great high ISO so most of us are not interested in Canon at the moment.
This thread is here to help the Adobe team make ACR better, please stop interfering with your brand bashing speaks.
Thank you.
