I own a 350D with a couple of lens, and also an S5, but the 350D sits at home while the latter accompanies me all of the time.
I'd love to take movie clips on most occasions - something which you cannot with a DSLR. And the movies from the S5 are good enough for home DVDs. I can even zoom optically during movie recordings, and something which you just cannot do even with a normal compact.
I'd recently went to Bangkok for a holiday trip - the zoom range, IS and video features are just fantastic. Of course, the IQ is not as fantastic - IMO, terrible noise even at ISO200, but the versatility of the S5 just makes up for it.
Now, how many people out there think the same way?
