Wow, I just realized this. Using Canon Digital Photo Professional (DPP), you have to download profiles for each of your lenses. Go to the Lens tab of the Tool Palette when viewing a RAW file to do this. Once installed, try it out. Works very well. Here's a couple tests:
The scene:
5D3, 17-40L
100% crop (straightened), DLO OFF:
DLO ON:
I recommend viewing each image in its own browser tab/window and toggling back and forth.
Another scene:
5D2, 35L
100% crop, DLO OFF:
DLO ON:
But, it doubles the file size of your RAW file, and you have to manually apply it to each picture, so I will only be using this before printing enlargements.
This takes pixel peeping to a new level!

My recommendation is to only load those profiles you will use, and only apply DLO to selected files, worthy of the process.

Agreed, but I thought I basically said this...? Not sure why anyone would select and download profiles for lenses they don't have.
Interesting side note, the profiles for all my lenses except the 35L were around 20-25 MB. The profile for the 35L is 3.5 MB. Guess it must be almost perfect!

Yes, the RAW CR2 file will be anywhere from 1.8 to 2.3x in size when you've DLO'd the image. So from there, you make your JPEF or 8 or 16 bit TIFF and take the resultant image to wherever you want. But what a lot of people don't realize is that once you're done, you can go back and un-DLO the image by deselecting the little box in the dialog and then SAVE again, and the DLO stuff is removed from the RAW and the file size snaps right back to where it was beforehand.
I love DLO!
Look for Canon to expand the lens offerings. As a bonus, DPP has a decent HDR engine included in the newest DPP. Note, the "fixed" and latest version is 3.11.26 which is free from Canon if you already have Canon software mounted on your machine. The included DPP with the early 5D3's is flawed, so don't use that.

Kind of a tangent but have you compared DPP vs. LR for color? I tried LR a year ago and just recently and both times I liked the colors in DPP better. Seems like DLO gives me reason to not worry about the little extra sharpness in LR anymore.
By the way DLO works on your 50D files too.

The default for LR is to not write timestamps into the raw file. If you do a bunch of edits in LR you can see that the date/time on the raw file does not change.

I hear ya. DPP is too ingrained in my brain for me to switch.
However, I discovered you can do DLO in batch. You copy the recipe from one image and paste it to the rest. It takes a long time though, and you do it before converting to jpg.

Good to know; haven't tried that yet. And, YIKES! One had better know beforehand they have enough room on a drive to do a large batch, much less the time aspect. Not something I'd want to do to pre-process a time lapse sequence.

Hello all,
since buying my Canon EOS 600D/Rebel T3i I've been working quite a lot with DPP. However, I can't seem to get the Digital lens optimizer to work. I've got the standard short and long zoom lenses (EF-S f3.5-5.6 18-55mm IS II and EF-S f/4-5.6 55-250mm IS) and a macro lens (EF f/2.8 100mm Macro USM). When trying to use the Digital lens optimizer, the appropriate tab on the Tool palette in DPP consistently reads "Lens data not available" with images taken with any of these three lenses. When trying to download them, the lenses do not appear on the list of downloadable lens types. Am I doing something wrong here? Your help would be much appreciated.

The DLO supported lens and camera combinations are listed on the second page of this link:

No, I don't see your current lenses listed. (I doubt that the EF f/2.8 100mm Macro USM would benefit much since it's already very highly corrected).
For software with similar capabilities I can suggest DxO Optics Pro v7.5.5. (You should not need the "Elite" version.) While it costs to purchase Optics Pro it does support a much broader range of cameras and lenses.

The list of Canon lenses that they support for the Canon EOS 600D/Rebel T3i alone is 3 pages long, and I believe at least some of your lenses are supported.
