@popo I don't know with certainty, but I think there's no AA filter involved in front of a Foveon sensor. I also have some detail pictures (the 50 mm of the little Merill goes as close as 0.226 meter) of textile or other structures which increase the danger of Moiré, but as each Foveon pixel (in that "older sensor, the new quattros are different) contains RGB, the don't need AA. Which I think, is the main factor for this kind of sharpness - no interpolation of 22% green, 63% blue and 71% red leading to this color
per pixel. They just don't need to merge the color values of 4 pixels to one.

 

I see it the same way, sometimes it appears overly sharp. And when it comes to fine texture, I'm always amazed about seeing a kind of "relief" (I just wanted to avoid the "3D" phrase, but I know what you mean). The prints of those pictures have a special quality. I try not to get used to it too much. The disadvantages of the concept can't be forgotten. But for a normal walk with no intentions in long teles… it's nice to have altogether 2 kg to carry, with a small tripod including the bag, two cameras in and the necessary spare batteries. It takes time and needs patience which is not always a bad thing.

 

See the little plane above the clouds? Bigger version And here's a gallery with some water and ice involved. 

 



 

In that gallery there was a little canyon, trees, plants, little animals like this 

 



 

Maybe it becomes a bit understandable why I'm defending Sigma and their cameras sometimes?  ^_^
