For me, now that I have my DA 560 perhaps I should take an I Don’t care attitude
, and I know canon, like Sony (who abandoned Minolta shooters as soon as they got market share) will survive by going to the mirrorless body and abandon their users AGAIN (to my count this will be the third time)
But... it is a shame that Pentax cannot collaborate with either sigma or tamron or develop at least one or two lenses with this range of reach.
As to the comment that the 560 is not very good, fine it is not perfect, but as far as I can tell, the only issue really is the one stop vignetting center to corner, that can be fixed in post. Size, ok it could be smaller but having used it now for 6 months, most of which is 5km plus hikes, and 1-2 hour duration I have made thousands of shots, mostly of birds and the lens never fails to impress. The fact that I have never, after working out properly how to attach it to a tripod, have I ever mounted it again on a tripod is a statement to it’s use ability . The sharpness, especially on distant objects is excellent and focus is spot on.
To prove that point I managed to do a few hand held shots of the moons of jupiter. It should warrant at least a replacement
