I've now also installed on a late 2008 MacBook Pro running the same operating system OS X 10.7.3 . This has an *intermittent* problem. It *sometimes* sees CR2+JPEG from the Canon S90 when I try to import, but sometimes only just the .jpg file. Have rebooted, and restarted LR4, a number of times - still only see .jpg on the iMac.
I am having this same problem with LR4 with my Canon 5D cr2+jpeg files. It imported the jpeg files but doesn't see the cr2 files with import dialog. I am able to copy the files off the card by hand without problem.
I've been trying to reproduce this, and haven't been able to. When I have "Treat JPEG files next to raw files as separate photos" checked in preferences, I see both jpeg and raw files in import. One thing to check...
In the import dialog, select the folder (or card) containing the files you want to import. Select "All Photos" in the top toolbar (right under Copy as DNG/Copy/Move/Add). Do you see the raw and jpg files in that view? Are the raw files dimmed? If so, it means they are already imported into Lightroom.
I have been having a similar issue which I reported on the forum during beta testing but no one seemed to take it seriously. The weird thing with mine is that it will import almost all of the files in CR2 but when it gets to around 400 files it starts to do every second or third as a JPEG instead of RAW. I have tried different settings but they don't seem to make a difference - I have found the only solution is to import from the card using 3 and then import just the RAW files from the hard drive (I separate them in to separate folders before I do the LR4 import). I was really hoping that this would be fixed in the full release but it is exactly the same.
To add more wierdness... if I quit import and start it again it fixes the problem...
I've had it be pretty random as well. Import will only see the jpegs, quit and it may work. Some times it wont load a preview for some image. Nothing has changed for me except upgrading to LR4. If I load up LR3 and everything works as expected.
I thought I would add I am having trouble downloading CR2 files from my EOS 60D while teathered as well. They don't even appear in LR4. I'm still using the beta which is set to expire on the 31st. I'd sure like this feature to work before I consider buying the software.
One thing of note though, is my videos do appear in the import screen (no preview is available though).
As it stands, I have to import my pictures from my Cannon EOS utility, then manually add the library to lightroom 4.
I am finding that it is semi random. I put my CF card into the reader and click import it will only show jpegs. If I hit cancel and hit import again, it will show the CR2 files just fine some times. Just repeating this a few times lets me import the files. This is new for LR4 and definitely seems like a bug.
When a card is inserted in my Card Reader and "importation window" automatically imports files (option checked in preferences), some RAW files are forgotten.
The card must contain imperatively RAW+JPEG files ( same issue ! None problem with LR1, 2 and 3)
Having exactly the same issue with this when downloading from a Canon EOS 40D to a 2011 Macbook Pro with Mac OS X Lion 10.7.3, only bought Lightroom 4 today - such a disappointment!
Tried importing my Nikon D800 files into Lightroom 4.1RC yesterday. I shot Raw & jpeg. At first only the jpegs showed up in the import window, so I cancelled out of the window, ejected my card from the computer and then reinserted the card into my card reader. Went to import in Lightroom 4.1 and now both the jpegs and the raw showed up. I proceeded to import, but it took a long time, perhaps 15 minutes to import 40 images. Finally Lightroom 4.1 ejected my card and started to make previews. Three quarters of the way through the progress bar, it simply hung up. I was able to quit Lightroom without a force quit. Then I restarted and found all the previews had been rendered. Erratic behavior with import on Lightroom 4.1 on Mac 10.6.8. Never had this problem with Lightroom 3. Thanks, Larry
Just imported another 34 images from my D800 into Lightroom 4.1 RC and this is what happened:
In import window, all images were selected, even though I had "do not import suspected duplicates" checked. Only jpegs were shown even though I had shot jpegs and raw as in my previous post. I cancelled out of import window. Re opened import window, now jpegs and raws did show up and all the suspected duplicates were greyed out as they should be. Import time was 1 minute 9 secs. Preview creation time was 1 minute---all very normal behavior. I had 17 raw and 17 large fine jpegs.
Seems I have to open the import window once with incorrect behavior by Lightroom--->then re open import window a 2nd time for import to behave correctly.
Same problem I have seen, but the workaround I found was to change the default folder (memory card) to the same memory card DCIM folder (in case of Nikon).
In the drives available for import, at the bottom appears the card reader (same as in the top), just click on it, click on the DCIM folder and then jpg + raw appears
I saw Dominik say the problem persists after installing the Lightroom 4.1 RC build. Has anyone else tried the 4.1 build? I hear differing results in other forums, so wanted to check the results of the group here.
