Somebody found out an explanation at Olimpus site saying that mentioned that the circle of confusion might be smaller (or different) on these "digital lens". I'm not sure this is the problem, because, IMHO the main issue is the angle at which the light hits the sensor at the edges... idealy a smaller angle would be better. This has do do with some kind of "retro-focus" geometry, I can't find a better way to describe it. In order to avoid a higher angle of incidence at the edges of the sensor the light has be "brought in" in a narrower angle, but still building the image size that you would expect from that lens focal distance. If the designers were playing with the circle of confusion, which I don't know if it is a parameter you can change without going into higher dimensional precision, and consequently higher costs, it would bring a significant change in the dept of field of that focal distance... those of you who already have these new "digital lens", do you see significant changes in the dept of field??? I think we are a bit in an era, like 20 or 30 years ago, when some wide angle lens were pointed out as "wierd" retro-focus!
