My primary reason for using Iridient Developer was to disable Olympus' built-in lens correction so I could recover more of the image at the edges. In my experience Iridient Developer did a good job on my Olympus files, but I didn't think it was noticeably better than what I could do in Lightroom. I am a longtime user of Iridient Developer. Lightroom and/or a pixel editor is still required with both O-Transformer and Developer, as there's no local adjustments or retouching tools in either version. It lacks many of the adjustments available in Developer, including cropping and exposure adjustments.

O-Transformer batch converts ORF files to DNG, applying a choice of two demosaicing algorithms, plus optional noise reduction, sharpening, lens correction and chromatic aberration removal. I guess they've had a lot of success with X-Transformer as they've now released similar "Transformer" versions for Olympus, Canon, Nikon and Sony. Developer is regarded as one of the best RAW converters for Fuji X-Trans files, and a while ago Iridient released a scaled down X-Transformer version limited to Fuji files for a third of the price of Developer, and which runs on both Mac and Windows (the full Developer version is Mac-only). Iridient Developer is the "full" version of the RAW converter that works for all RAW files from all cameras.
IRIDIENT DEVELOPER OR X TANSFORMER FOR MAC
It's available for Mac and Windows for USD $30. I just noticed that Iridient Digital has released a version of their RAW converter for Olympus ORF files: Iridient O-Transformer.
