And your point?
I would assume most of the people buying these lenses are getting them for the long end. It is also way too soon to really comment about the optical qualities of the Pentax lens, isn't it? I know folks make up their minds quickly, but as of right now, I have seen a couple of decent photos, but a lot of photos that I would have probably deleted on import (if not before). But image quality is the question.
I would also say that as of right now, the biggest thing holding back Canon lenses is Canon bodies, which are fine as far as specs, but lag a bit with regard to sensor performance. I would definitely prefer a K3 or a D7200 to a 7D MK II as of right now for my style of shooting.
People who are interested in this lens will not be bothered by a little larger lens, as long as the image quality is there, nor will the lack of optical stabilization in the lens be a problem as long as the K3 II really is that much better than a K3 in the stabilization department. Finally, I would not compare the price of a brand new lens to that of a lens that has been out for a little while. Price on release is not necessarily the price that will be on the lens in six months and street prices are often a little below MSRP.
I hesitate to say anything else, as I really don't know what the performance of this lens will be like. I think it will be pretty good, at the least, but I certainly don't know enough either to pan it or, to give it accolades. Cautious optimism would be my point of view at this point.
