Search for RAW files by lens or even focal length

I'm trying to find all of the raw files that were taken with my EF 135mm f/2.8 SF lens to find a specific photo that I would like to process from a few years ago. There are tens of thousands of photos to go through.

Is there a software tool that would easily search by lens type or even just focal length?

Do I need to write a script to run exiftool on each file and let it recurse the folders for a few days and save the paths to the files?

Lightroom is capable of such a search...

If you are running Windows, Explorer can do it if you point it at a photo folder. In the Details view right-click on the details bar, select More and from a long list select such attributes as Exif-Lens, Canon-Lens or Jpg-Lens.

But as said above, after you have imported all your photos LR will search all of them.

Thanks for responding. Unfortunately I only have Windows XP Pro. It has many optional columns such as camera model, but not anything with the lens, or even the focal length. Also it only shows extra info for JPGs and Tiffs, not CR2 raw files. Windows search won't do it either.

I have Photoshop CS2 with Bridge but this version of Bridge won't search by EXIF tags unfortunately.

I don't have Lightroom but I'll look into seeing if there is a demo that I could use for this project and then remove after.

What are you using to process your Raw files? I'm checking out the Canon software and can't find anything there to help do a "filter by lens" the way Lightroom does.

Strange, I have XP Home and it does CR2s also, but maybe that is because an applet that I have for putting CR2 thumbnails and exif into Explorer gives it that ability also.

I use DxO Optics Pro for raw files. It doesn't have the ability to search this way. I've also tried Photoshop CS2 Bridge search, XnView search (almost works), Windows Explorer, Locate32, and Canons DPP and Zoombrowser. I just downloaded GIMP to see if it does it. It appears that ACDSee might and it isn't expensive.

I even loaded the current Canon RAW codec into windows but it doesn't seem to add any functionality to Windows. Microsoft used to have a RAW viewer for Windows available that added some things. I should look to see if that is still available.

I'm not at home now where I have a bookmark for that applet, if you are interested, but I posted about it last week so I should be able to find that post in a couple minutes.

Here it is:

Thanks, I'll give that a try.

You can use Bridge to find your files.
Using ExtendScript Toolkit you could run the following code, make sure you change the LensToFind first, a text file will be created on the desktop with the results.
I have just tried it with 10,000+ files and 80+folders deep and it took 10 seconds on my laptop.

#target bridge
function getLensInfo(){
var Loginfo = new File(Folder.desktop + "/Lens Found.txt");
Loginfo.open("w", "TEXT", "????");
$.os.search(/windows/i​)  != -1 ? Loginfo.lineFeed = 'windows'  : Loginfo.lineFeed = 'macintosh';
var folders =[];
var topLevel = Folder.selectDialog("P​lease select top level folder");	
folders = FindAllFolders(topLeve​l, folders);
folders.unshift(topLev​el);
//change lens info to suit
///////////////
var LenstoFind = "75.0-300.0 mm";
///////////////
for(var z in folders){
var fileList= Folder(folders[z]).get​Files(/\.(jpg|tif|psd|​crw|cr2|nef|dcr|erf|ra​f|orf|mrw|mos|srf|pef|​x3f|raw)$/i);
for(var a in fileList){
   if(!fileList[a] instanceof File) continue;
var Thumb = new Thumbnail( fileList[a] ); 
var md = Thumb.synchronousMetad​ata; 
app.synchronousMode = true; 
var Lens ='';
md.namespace = "http://ns.adobe.com/e​xif/1.0/aux/"; 
Lens =md.Lens; 
if(Lens == LenstoFind) Loginfo.writeln(decode​URI(fileList[a]));
        }
    }
Loginfo.close();
alert("All Files Processed");
}
function FindAllFolders( srcFolderStr, destArray) {
	var fileFolderArray = Folder( srcFolderStr ).getFiles();
	for ( var i = 0; i < fileFolderArray.length​; i++ ) {
		var fileFoldObj = fileFolderArray[I];
		if ( fileFoldObj instanceof File ) {			
		} else {
         destArray.push( Folder(fileFoldObj) );
		FindAllFolders( fileFoldObj.toString()​, destArray );
		}
	}
	return destArray;
}
getLensInfo();

Thanks,

I didn't know that Bridge was scriptable.

Yes Bridge is highly configurable via scripts and there is a lot you can do, for more info..

Thank you very much for that. I updated my ExtendScript version from 1.0.0 to 1.0.3 and then adjusted the script. This is working excellently. The only thing I can remember about the photos that I am looking for is that I took them with the EF 135mm f/2.8 SF lens. I don't remember when I took them, what they were named, or even which camera body.
