Hi David,
when you use DAC, do you lose image "real estate"? As far as I know DxO delivers around 96 % of the original image and Canon DPP only 92 %. And if, does it depend from the lens?
Best,
Johannes
Yes you are correct in assuming it will depend on the lens. Distortion is non existent in the longer lenses so real estate is 100%.
Obviously the HCD28 requires the most amount of correction. I post two images from the HCD28 so you can layer them in PhotoShop and see the difference.

This image has no distortion correction.

This image has the distortion correction.
