Currently I'm using Lightroom 4.4 and I do not plan to upgrade at the moment. But I want to buy the new EOS 70D.

Today I read that Lightroom 5.2 will support the EOS 70D raw-format. So what did this mean for me? Can Lightroom 4.4 work with EOS 70D or do I need to upgrade to 5.2?

Lightroom 4.4.1 is actually the most recent version of LR4, it was released a few days before the EOS 70D, so no it does not include support for it. It is possible they could update LR4 to support it but unlikely. –  dpollitt Sep 18 '13 at 12:44

Lightroom 4.4 will not support Canon EOS 70D raw files, no. You would need the latest Lightroom 5.2 for that - as you say.

However you do have the option to use the latest version (8.2) of Adobe's free DNG converter, which does support the 70D files, and will convert them to DNG "Digital Negative" files - which retain all the information of the raw files, but which is a more standardised "open" format, which Lightroom 4.4 will be able to import.

It's a bit of a faff -- but it's free, and will save you having to buy LR 5.2 (though there are other reasons why the upgrade is worth it - but that's conversation for another thread! ;) )

faff? Can you define? –  dpollitt Sep 18 '13 at 14:17
    
Thanks Mike for "Adobe's free DNG converter"-tipp. Under all conditions (quick workflow, new features) I consider to upgrade lightroom ... :-/. –  Micha Sep 19 '13 at 4:57

You just think that DNG retains all of the information of the RAW file, until you try to convert them back to .cr2 to open them with an application that can't read DNG. DNG strips all of the metadata that LR/ACR ignores, such as focus point selection in Canon files and CLS data in Nikon files. And you can't convert them back to .cr2 or .nef, so if Canon or Nikon comes up with a better processing application (i.e. Canon's Digital Lens Optimization that can mitigate the effects of diffraction) to leverage the proprietary parts of their RAW files your DNG files can't leverage that. –  Michael Clark Sep 19 '13 at 9:36

Although not required by the DNG standard, Adobe's DNG convertor also calculates black point and strips the data from the masked pixels so that it can't be recalculated later. The standard also allows for the 'correction' of defective/stuck pixels. But what if the identifying algorithm mistakes something like a star for a stuck pixel? It is gone forever.

You will need to upgrade. There are a number of bodges you can do, for example editing the .CR2 files so that they "pretend" to be (say) a 60D rather than a 70D, but then Lightroom will be applying the wrong optimizations and so you'll get lower quality results.

Thanks Philip for answer so quick :-). Editing CR2-File is interesting idea. I think lose optimizations an bringing a new step to my workflow isn´t the way I want to go. So I have to upgrade ... :-/ –  Micha Sep 19 '13 at 5:00
