Will there be a lens focal length filter in LR3?

I find the aperture filter useful and recently needed to find focal lengths used for three of my lenses. Had to export thousands of jpegs for each lens to drop into a another program to get the information.
Grouping FL together would give a resonable filter ( 20-25, 26-30, 31-35,36-40 etc etc)

Just clicked Forum (german adobe-website) in the Lightroom section. Sorry if I chose the wrong board :/
The camera only can shoot RAW. I think even my Canons can't shoot DNG if I'm remembering right.

Filter by lens focal length?

I would like to get an idea of how frequently I use different focal length settings on a particular zoom lens. The focal length used on each shot is in the metadata. I can see it shown right under the histogram in Library mode. Is there some way to build a custom filter to select photos with a focal length between 24-32 mm, for example?

Jeffrey Friedl has written a LR plugin that should address your needs:
Taken from his page:
"This plugin is designed to fill a specific hole in Lightroom's “Grid
Filter”, adding new fields by which you can filter images: “Focal
Length” and “Focal Length in 35mm”. The
former is the raw focal length of the lens, while the latter is viewed in
terms of the frame size of a 35mm film frame."

Lens Focal Length with Phase One P21+

Hi,
When importing images without converting them into DNG I have the following situation in LR
When using the Developer module I can se the focal length of the lens, but when in Library Its not visible anymore ?

Hi,
Thank you for the fast answer, When looking at the screen I have ALL selected and it tells me unknown lens.

Lens information and focal length (35mm) not showing up

I'm using a Canon 20D with several L lenses and I have yet to see any information show up in the Focal Length (35mm) field, or any of the lens information fields. I would think this would be a pretty common combination and I'm wondering if there is anything I can do to get this information.
For focal length, since it does know my camera type (i.e. 20D) can't they just multiply all the lens focal lengths by 1.6 my FOVCF?

the sensor size in the camera does not alter the focal length of the lens - it just results in an image with a different field of view to a different sensor size. Focal length is a characteristic of the lens and has nothing whatsoever to do with the camera body it is attached to.
The lens will always be a 28mm or 50mm etc so why would Aperture or any other software say it is a 45mm or 80mm lens? The image will not look the same as if you had taken it with an actual 45mm or 80mm lens, so it would be incorrect to show it as such...
Aperture should simply show the actual focal length for each image - we translate that to whatever is helpful for us to understand the results.

Sort by focal length

1. Metadata Browser: sort by focal length (using a cushioned range)
2. Ability to filter based on focal length: i.e. with 3 criteria lens, focal length, aperture it would be super simple to paint in presets for removing natural vignetting.

Ian,
The post in which I repeated your comment was not directed at you, the quote was used to re-iterate that it is accepted that the feature is currently not available, and that the search feature is very limited.
If you feel my post was directed at you, my apologies. If you reread the post, the only two times the word "you" was used was in the following way:
>"If you build it, they will come..." well, "If the information is there, you should be able to search, filter, or create smart collections by it."
The comment should have started with "With all due respect to the LR team..." because I hate harping on a subject, with anyone. However, this thread was initiated on July 10, 2007 and covers an issue that deserves to have been addressed by now.
After all, LR is a database program designed with photographers in mind. All databases work in the same way:
1. They provide a way to input/gather information
2. They store the information in fields, and
3. They allow you to obtain that information through reports, or other means, so you can use it constructively. LR gathers the focal length information separately from the lens information. Therefore, it should be easy to program it to allow you to filter/search/create collections on the information.

Smart Folders and Filtering based on Focal Length

Can we please be given the ability to create Smart Folders and be able to Filter images based on focal length?
Doing so based on Lens alone does not take into account that more and more people rely on zoom lenses. When you have 16-35, 27-70, 35-135 and 70-200 lenses, one could benefit from having the ability to search for images created in wide-angle, normal, zoom and tele-zoom ranges.
Providing this feature would be greatly appreciated.
Regards, JML

Thanks Colin, I will try it.
Sounds like it may work - however bit awkward solution in otherwise ergonomic LR environment :-(
I really do not understand why this value is not among the filtering metadata when LR recognizes it and shows it on every corner. Especially considering the fact LR is supposed to be full WF solution and certain development settings cannot be effectively applied without selecting images only with certain focal length values.
The very last feature I am missing on this SW designed to cover entire WF (since LR1) is the distortion/perspective control and ability to apply corrections based on lens/focal length used.
b Does anyone have an idea if Adobe plans to eventually implement this feature?
I do not want to be forced to use DxO which always means interruption of the WF and inevitably generated new files on disk.

LR Filters ADD custom filter for Focal Length

I use a Leica M8 and in it's metadate there is a field for focal length of the lens but not the lens name/type and in LR filters there is a filter for Lens but not for focal length.
Is there a way to add a custom entry in LR to filter images based on focal length?
Found a way with smart collections.
Thanks

Care to share how you did this?

Seeking method to change what is displayed in Filter-- Focal length

When in Bridge under the Filter tab-->Focal length what I have listed is 5mm, 5.8mm, 6mm, 6.2mm, 6.3mm, 6.5mm etc. etc. and the list goes on and on. The conclusion being that this list is way too lo0ng to serve as a good filter to me.
I sold all of my lenses 2 years ago and replaced them with one zoom lens (and at times a pocket camera also with a zoom). I couldn't care less if the photo was taken at 6mm or 6.2mm. To me they are just about the same thing. However, I would like it if it actually game me a range say 5mm-10mm; 10.1 mm-15mm etc. Now the filter makes sense to me being more manageable. Is there any way of making it so?
In other words I no longer want to see:
5.8mm,
6mm,
6.2mm,
6.3mm,
6.5mm
But would like instead to see:
5mm--10mm
10.1mm--15mm
15.1mm--20mm
Which are in increments of 5, BUT, increments of 10 would be fine as well or even better.
Thank you

Doesn't anyone like my question? :-(

Library Filter: Metadata Browser: Add Focal Length

Please add Focal length as an available Meta data to browse in the Library Filter.
Purpose:
I'm currently considering to buy a new zoom lens. To determine the best zoom range for the lens, I like to see which focal length I use most often by profiling my existing images.
The information is already available in the images exif data, it only needs to be exposed in the Lib Filter.

Lens Correction? Search by Focal Length?

Does Photos for Mac support lens correction of RAW files? Can you search or sort photos by focal length?

Can you search or sort photos by focal length?
In a manner of speaking. You can create a smart album with the following criteria:
Right now there's no capability for editing with a 3rd party editor from within Photos. Ask Apple to add that feature via http://www.apple.com/feedback/iphoto.html and http://www.apple.com/feedback/macosx.html since they don't have a feedback page for Photos as yet.

Feature Request - better croping, focus patterns,focal length selections?

Tool specific Keyboard shortcuts: It would be helpful to have popup clues about keyboard shortcuts. For example, when using the crop tool, it is not obvious that typing an "X" will change the crop tool from a portrait to landscape mode or repeatedly pressing "O" will cycle through a number of grids. (Thank you Matt!)
Crop at other than "Fit" setting: Other crop tool request - allow crop to work on image at settings other than "fit" I may be able to get a more accurate crop at 1:2, etc. Otherwise I have to crop an image roughly, make a virtual copy and then crop again. Is there a better way to do this?
Show Focus Points on request: If you shoot wildlife with a long lens, a slight error in focus can ruin the shot. I review my bad shots to determine patterns of error in focusing. It would be helpful to see the focus points that were used in Lightroom, (e.g. killer whales move differently than an egret....) I assume this is stored in the metadata. I'd love to be able to do this in Lightroom.
Add Focal Length to filterable metadata fields: It would help to be able to see the various focal lengths used during a shoot, just like you can look at apertures (i.e. select folder for shoot, turn on filters, select aperture in the metadata and wallah! you can see the distribution of apertures used during a shoot.) This reminds you to mix it up and/or helps with lens selection. Is there a way to do this now?
My apologies if these features are available and I just haven't found them yet.
-TAB, a lightroom fan
P.S. Thank you for the wonderful new features. I can't wait to convert my existing catalogs. I love the new import dialog. Now I can organize my backup copy in a logical fashion. When I'm in the field on a multi-day shoot, I don't want to risk reorganizing the backup. Now I don't need to. Enough has been said about noise reduction and better rendition. Thank you!!!

There is a corresponding idea at the feedback forum: http://feedback.photoshop.com/photoshop_family/topics/add_image_direction_in_map_module
Anyone who wants this feature should also vote over there...
BTW: +1
Edit: P.S. I think it is generally a better idea to post feature wishes in the feedback forum (or comment on existing ones there) because it's regularly monitored by Adobe employees, while that is not necessarily the case for the user-to-user-forum here.

How to shoot fixed focal length lenses?

Hi,
I wonder how I am supposed to best shoot fixed focal length lenses.
Currently I just shoot one set of 9 images, just because it is a fixed focal length lens and if I want it to be good, I shoot the same set again with different apertures.
But the documentation says: "For prime lenses, shoot at (1 × minimum focus distance) and (5 × minimum focus distance) focus distance positions with a fixed f/11 aperture."
My problem here is to understand how I am supposed to shoot with different focus distances while using a fixed focal length lens?
As far as I have understood until now, I have to put the test chart fully on the picture so it fills something about 1/2 to 1/3 of the picture, leaving room everywhere. I also input the type of chart I used in the software.
If I do this, then moving the camera to say 5 times the first distance makes the second set of picture agaisnt the rules since obviously the test chart will show only much to small.
If I do it the other way around (first 5x then 1x min) then the second set will only show fractions of the chart.
As added difficulty I wonder how to handle macro lenses... the minimum focus distance there usually allows for a 1:1 magnification. That would either require a test chart total size (!) of less than 1/2 an inch (fun printing) or you would only get to see a fraction of a test-chart-square.
So how do I do it?

No, I am not confunsing these terms. I thought of it exactly as you described, but that seems not in sync with reality or guidance given - for the following reasons:
1. I do actually own a 35mm macro lens with minimal focus distance which I want to create a profile for. Minimum focus distance is 13cm with magnification 1:1. The latter means that the picture is completely filled by any object that is as big as the sensor. --> The full test chart needs to be less than 2cm small.
In that regard your example of a 400mm lens is the easy thing because of the 12 feet distance. Anything is easy to shoot from 4m aways as you can use normal charts.
2. As I described the guide says that the chart should fill about 50% of the picture and you should use one chart. Even in your example obviously the size of the chart on the picture will vary in a real big way if you shoot the same chart with a 400mm lens from 12 feet and from 60 feet. I just wonder if that is what is correct or one should choose a different chart for each distance (I dont believe that).

Focal length in Metadata panel

I notice that in the metadata (Info) panel one can see the focal length used and below that, a blank field for the 35mm focal length. Is there any way to get Aperture to fill in that empty field with the 35mm equivalent to the lens's actual focal length?

Thanks for that. I did as you suggested, but my current libary has only recent images all from one camera, which doesn't produce RAW fles, the Ricoh CX4. I will go back to an earlier library where I have several cameras involved included two whose raw files are processed by Aperture, and i'll bet I'll see the 35mm equivalent.
Is there any way I can tell Aperture the formula for my CX4 lens such as that its minimum focal length of 4.9mm is equivalent to 28mm on a 35mm camera?
In any case, I am happy to know what you just told me, because I will be using Aperture to process images from two other cameras it does recognize. By 'recognize' I mean it will process their raw files.

IPhoto 6.0.5 Get info regards focal length of picture taken???

When I display a photo and want info on that photo I go to Photos, get info and focal length. A small number 7.19 mm seems to refer to a wide angle view while a larger number 28.81 mm refers to a telephoto view I think. If this is true what is the multipler that gives me the numbers that apply to a non-digital camera. 35 mm and 200 mm make more sense to me than 7.19 or 28.81 mm. If the numbers do not refer to this what do they mean and where can I find the 35, 200, 400mm numbers. Well, stupid me, just plugged some #s into the calculator and it appears that a 4.86 multipler works out to be 35 and 140 mm the G5's focal length. Now another question instead. Can I change in preferences somewhere a setting that will make that calculation and display the 35mm, 140mm numbers instead?

ef1:
Welcome to the Apple Discussions. No, the information is added to the image file by the camera and iPhoto just reads it. There's no way to recode iPhoto to add the multiplier. Just the nature of the beast. If you wanted to edit each file individually to change the number to reflect the value you want. There's an application that will let you edit those fields. It's called Reveal.
Otherwise, create a jpg with a table of converted focal lengths and include it in iPhoto for quick reference.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application, iPhoto dB file backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar

Getting images w/ different zoom/focal lengths to match up?

Hi! I recently shot some star trails the other day with a 20 second shutter speed. i ended up with around 150 pictures but when i went to blend them, the trails didn't match up! i later discovered that when i went outside to clean off the lens (which was every 10 mins) that i accidentally zoomed in a little each time i cleaned it (ranging from 11mm to 13.6mm). I put all the images into photoshop and blended the ones that were shot with the same focal length (i ended up with 5 layers)I was wondering if there was a way/feature or if you guys knew any tips or tricks that would crop the image and line it up to match the other trails for me automatically or help me crop the images to the right size. Thank you and any help is much appreciated!! (:

Do your images have any easily identifiable landmarks in the foreground - buildings, trees, etc.? If so, you could use the Measure tool, and figure the necessary scaling from there.

Will there be a lens focal length filter in LR3?
