Now they cover every lens I own.

I wonder if there is a way to make LR automatically select and apply the correct lens to every photo as it imports....

Been using LR about a year and never understood how to use this feature. Just updated to LR3 last night. Tips ?

Tips ?

You have to activate it in the lens corrections panel by checking a box. If the lens used for the image is in the database then it will activate. You can then disable it manually. Most positively notable on the DA Ltd 15mm & 21mm. It's almost like getting new & improved lenses.

This is more automated on RAW files (I haven't tested jpegs). If you import tiff or PSD images the tool is clueless about what lens is used even though the exif data is accurately displayed.

By checking the box the corrections will be automatically applied in the Develop module. That said, I don't recommend applying lens corrections until near the end of your workflow as it slows down LR significantly. LR 3 is already slower than earlier versions, and this compounds matters further unfortunately. Doesn't make it unusable, but when I import a couple thousand images, it does try my patience. On those large jobs, I'll defer lens corrections until the very end and simply paste the settings on everything relevant in grid view.

Still LR is the most efficient and best tool for post processing.

This sounds quite interesting, does anyone have before -> after examples, preferably with the 16-50mm f2.8?

Here is an example for the 16-50 f2.8 which shows the CA removal. It's a crop of a corner.
update: added another picture. Vignetting and distortion is also well corrected.

Wow, it's more noticable then I expected. Time to upgrade. Thanks for showing these examples.

Well, I remark the following:In the first "folder" of LR (in German called "Bibliothek") there is still no indication of some of my lens used, e.g. 60 - 250, in the camera metadata section.
In the "Develop" Module however this lens is presented in the lens correction module. What I am usure of, is, if this came with LR 3.3 update or if this is result of my lens import by the Adobe lens profile downloader.
Still find it irritationg that the lens is not shown in the camera metadata section of the "Bibliothek".

Don't have them at hand, but the corrections applied using the profile I made myself a few months ago are dramatic in terms of distortion, vignetting and CA. I assume the same for the new profile.

As a rule, I would recommend activating the corrections only for subject matter that would benefit from them. Of course, this is a personal choice. For architecture is a must, for the rest it depends... LR does indeed slow down because of these corrections, but the degree in which you will notice depends on the power of your hardware.

Fully agree here, it's like white balance - it's "precision" vs "accuracy", "perfect" vs "best", "scientific" vs "artistic"...

Was surprised to see that my DA 40 become supported after upgrade. Now if only DA 18-55 WR would actually show up as a lens with a name instead of "unknown lens" :ugh:

But they excluded [or didn't get to, due to extent of work] the lens that most needs correction.... the 12-24/4. :ugh:

On the other hand, Sigma 10-20mm is supported... get to your game pentax! 12-24 is a DA* without the * after all.

The algorithm for correction already exists in all cameras post K-7, so it shouldn't be that hard give that to adobe and correct all DA lenses.
