Hi Klaus

I read the article and info on the HR conversions wih interest. You say you do not recommend it to normal users. Why not? The increase in sharpness on my D300s seems fantastic. Are there disadvantages, beyond the price? Kidly Vieux Loup

Have a look at the Oly sample image:

In the middle portion of the image there's a roof top with some kind of fine rock gravel:

You can spot some funny colors in there (probably a demosaicing effect in conjunction with the excessive resolution).

In the maxmax samples you should also be able to find some moirees in the artificial test targets.

Often this is not disturbing but it can be a show-stopper - e.g. macro photography, bird feathers, hairs - things that are "stacked" and "straight".
