I looked at these super zooms in my search for an affordable long lens for bird shots,
setting price aside for the moment - Will these plastic extension tube super zooms ever realistically compete with a good DSLR prime?
I agree that the latest "compact" cameras are really good and competitive versus a DSLR at the shorter end and that M43 cams are good up to say under 200mm (I have an S95, G1 and EP-1) - and that small sensor technology is getting better and better.
I also have an M8 with good Leica and Zeiss glass and when I need a closer image I get very good results thru cropping, (god forbid to crop a Leica!), but isn't a crop just equivalent to all this digital zoom publicity that is now included with the usual super zoom specs.
For me, cameras are still "horses for course" for the enthusiastic AP and the Fuji X-S1 - "fit all super zoom from 24mm to 624mm then x2 up to 1248mm with an "Intelligent Digital Zoom" is just there to suck in the punters ........ OK I am sure that it produces results ........ but what results.
I like my S95 for most of what it does, the same goes for my M43 stuff and my M8 - but I will still keep my D300, (and upgrade), especially for use at the longer end and with Nikon zooms - (plus, now a Nikon prime or two when I decide I can afford them).
just my opinion - but, I still think that to get what you want you need to pay for it and getting a load of stuff in an "all signing and dancing" camera, which maybe a compromise on the IQ and the functionality that I want is not only a waste of money but also a waste of effort.
There is still a lot in the saying "buy good glass"
as I said IMHO
