Originally posted by pres589 Why would lenses that were "sharp enough" on 10, 12, or 16mpix become soft at 30 or 40mpix? Did users experience that when going from the 6mpix cameras to 20mpix or greater with lenses like the 16-45 or other similar era lenses? This is in no way saying that the 16-50 doesn't need an update...
I'm not saying that. What I do know is that, for instance, my DA 15 limited is pretty soft on the edges on 24 megapixel K3 sensor till I get to at least f8. Of course, it won't be worse on a 43 megapixel sensor, but it won't be better either. The same with the DA *16-50.
I think the DA *55 and DA 40 and DA 35 limited would all do better than that, but I think we all know that you reach a point of diminishing returns. You bump resolution a bunch but somehow you just don't get that much more detail. Maybe it is that the lens isn't up to the task, maybe you just can't hand hold that pixel density, or maybe there is something else going on that limits things, but what you get is a lot bigger file, but not so much more real resolution.
