If you have the Workflow understood first time, the processing is proceeding very swiftly. One must take the time to familiarize yourself with the many possibilities of the software in any case. Then, it makes a lot of fun. And a camera may not provide as good JPGs - Lightroom still capable, top it. Many correction possibilities make a post often superfluous in programs such as PS, PSE or GIMP. Whether remove red eyes, a history, a vignette or partial exposure compensation - Lightroom can.
The only real drawback in my view: Just a Oly users will miss the lens profile. It's almost all there, but just the optics of Olympus that are missing. That's why I deducted a star. Half would have been enough ... ;-)
I have added the fifth star. :-) The lens profiles are stuck at the M.Zuikos in the EXIF data and are therefore not displayed in LR.
