For my early trials with the 90D, I used PictureCode/PhotoNinja as RAW converter (via .dng files produced by Photoshop). It processed the files very nicely and suppressed noise very well. I couldn't use my favourite DxO Photolab until PL3 came out. Unfortunately, the PRIME noise suppression leaves a horrible grainy noise that doesn't get suppressed by the Luminance slider when the Lens Sharpness tool, which is tailored to individual lenses, is used. Do others find this with their 90Ds and M6 IIs?
