this is patently a question asked by somebody who has not used one. having gone from a Canon A1 SLR in my early days throught the point and shoot digital to the very clever Nikon 995 and now to a D70 all I can say is that I have come back home. The ease of taking the photograph, the ability to see what I am taking - rather than squinting at some minute screen in the sunlight, the ability to actualy be at one with the camera and the photograph make me realise that if you want to take snaps use a P&S, if you want to take photographs then there is absolutley no choice but an SLR - just see how many professionals use any other medium and then ask yourself why
I understand the use of an SLR with film. It allows me to preview
the image without parallax, and it allows me to make best use of a
zoom lens etc. That's why I have used SLR's since 1968 (Nikon F,
then Nikon F100).
With my Olympus 8080 digital camera, though, the CCD chip
transmits the image in real time to a LCD for immediate preview of
the true image projected upon the chip. There is no parallax, etc.
My 8080 shows me exactly what I'm going to get if I press the
shutter release. What more would SLR optics do?
It seems to me that SLR optics only add cost and weight to the camera.
