I expect Adobe to drop the full version of Lightroom 5.2 any day now. It’s been a full month since the Lightroom 5.2 release candidate was made available and preliminary support for the 70D was included.
Those of you looking to work on your Canon 70D raw files can do so with the release candidate. Or, if you have Aperture 3, Apple has already made full support for the 70D available in it.
Thank you for providing excellent information regarding digital imaging. I just want to point out that I test a Canon 70D yesterday with my SD card and my current Lightroom 5.0 reads both jpeg and RAW files just fine without update.
