I use a Sony NEX-5R, with Lightroom 5, on a Mac.
Bundled with the camera came two pieces of OEM software: Sony's Image Data Converter and Canon's Digital Photo Professional.
I had a quick look at the former, and it doesn't seem to do much that Lightroom can't. Is that impression correct, or am I missing significant capabilities by ignoring these and sticking with Lightroom?
In particular, I can't imagine Canon's software doing something unique for a Sony camera.
