but remember a DSLR is not a refined tool - it is an advanced photographic tool, but it is not specialized for a specific use in the same way as say a sports car is specialized for speed.
So you get features for macro that studio shooters won't ever touch - video that the press will use - mirror lock up that sports photographers won't use....
the list goes on
*ps examples given are only rough - none are perfect of course*
True, but then most photographers don't know how to use their camera bodies to the fullest anyways. Especially with the custom functions now available on DSLR camera bodies. I would submitt that the basic features of an SLR or a DSLR are still features that a photographer would want to have available. They are not the same features that a cinemaphotographer would necessarly want to have for their work. Are their times when there might be a want for a crossover. Yes. Is it something that is wanted on a day to day basis by the majority of the serious users?
I would suggest however that the DSLR is a refined tool. Not as refined perhaps as the older SLR's but still refined. An SLR and the DSLR are designed to take still photographs. A movie camera and the modern digital camera are designed to take sequences of film or images. Their workings are quite different for their basic function.
Even though my old 8mm movie camera that the folks gave me had three different lenses on it that could be rotated allowing for more flexability, I never once thought for a minute that it would replace the 35mm production movie cameras. I was right, it never did.
While point and shoots will undoubtly improve in function and quality so will the DSLR's. They will coexist in the world of photography each having it's own distinct advantages and disadvantages.
