Originally posted by dgaies I understand what you're saying, but I'm not sure I fully agree. Unless you want the smaller size and compactness of a bridge camera, the K-5 + 18-250 will give you superior IQ (IMO). Even if the long end of a bridge camera is a stop or two faster than the 18-250 at the long end, the difference in high ISO performance between the K-5 and the just about any bridge camera is a lot more than one or two stops. Plus, the DSLR + superzoom is generally going to be more respoinsive. The bridge camera is obviously going to be smaller, lighter and a lot less expensive than a K-5+18-250, but again, if you don't mind the size and already have the K-5, I think the 18-250 is a perfectly reasonable lens to buy for this purpose.
Not to hijack the thread and make it a DSLR + superzoom against a Bridge camera discussion, I think you will gind that the high ISO performance on the K5 while exceptional, grew out of the development of higher MP P&S/Bridge camera sensors.
I won't disagree the high ISO capabilities of the K5 are great, but the point I was making is that the bridge cameras do come with fine lenses, which are fast, compared to a super zoom, and it would be an interesting test to shoot a super zoom vs super tele.
But I think that the super tele has so many drawbacks, that it really won't do a K5 justice and for many applications a bridge camera is a very capable alternitive.
as for responsiveness and other capabilities such as flash etc, I agree a K5 wins hands down, but there is a place for a bridge camera, as a small light weight walk around as good in most daylight situations as a DSLR and super zoom
