Blurred photos in Lightroom when in Loupe mode

Hi, since I have purchased Canon 5D mkII i have some issues with lightroom 3.2. Photos seem to look blury when in loupe mode, but when I switch to develop mode and then back to Loupe - mostly they become OK, but not always... I tried dismiss previews, render them all and so on, but nothing helps.

Maybe someone experienced that? Photos from Canon 40D never did those issues...

But 5D mkII (RAW, the biggest ones) do... And sometimes even I cannot determine if photo is trash (out of focus), or simply good, but looking trash (since I haven't opened Develop module...).

Maybe this is because when I switch from Develop module to Library, the photo size increases a little bit?

Well, Lightroom by default doesn't render the highest quality image, in order to save time. One thing you can experiment with: take a folder of photos, select all (Ctl-A) then render 100% previews, either through right-clicking or through the menu system, although I'm not at my workstation with Lightroom. Open Help and search for "Preview" and after clicking through a few times you should get good info for working with previews.

If the 100% preview improves things you may be happier setting your preferences to render them automatically, but be aware that this will slow things down. I have my system set to render Standard previews and even that can be time consuming on a shoot with hundreds of photos.

As to why the 5D2 previews look inferior to the 40D photos, I'd imagine it's a simple problem of the high resolution 5D2 files being over-compressed for viewing the smaller previews, but I really don't want to try to hazard a technical guess here.

Thanks for the response. The problem is that `render Standart previews` renders them only the first time after photos are imported. And then it seems they stay the same unless you go to Develp module and go back, or zoom to 100% and zoom back...

I will echo what Bob A suggests. I had the same problem with Lightroom and switched my Standard preview to the same as my Screen width - problem solved. However I will say that the downside is that full size previews on a 2048px wide monitor ( which I also have) does take a bit of time to process after import, and do take up more HD space. So make sure you set the Auto Discard appropriately (I keep mine set at the 30day, as it is unlikely I will still be editing a photo after 30 days. and if so it is one offs, not a whole import.
