I'd never used DPP before, but yesterday I edited some 5Div food photographs with it... it is indeed a mess compared to Lightroom. In the middle of editing I noticed Lightroom was updated. I was ecstatic.
But I must say... Lightroom's decoding of these files is much softer than DPP. It's that heavy low-pass filter look seen in all the early samples. Meanwhile, my photos look much sharper in DPP. Then you turn on DLO and they get even sharper.
Lightroom also does not have a profile for Canon's new fine detail setting... which I'm loving for my food photography.
It's a bummer as I've been using Lightroom for years, but DPP's decoder looks so much better right now. There's no way I could edit 500 vacation photos in it, but my food photography creates only a few photos that need editing per shoot. So I'm going to stick with DPP (then Photoshop) for now.
Here's a photo of low-carb Strawberries & Cream Popsicles from my first shoot with the 5D iv.
