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.
I've tried both, and I personally much prefer my *ist D's viewfinder to any of my digicams' LCD previews.
But, if I could have a camera that was the same as my DSLR in every way except that instead of a mirror, pentaprism, and viewfinder it had a big LCD preview that looked just as good as my viewfinder (even with manual focusing) and had no lag, and had a collapsible bellows or something around the LCD to shield bright light, and if the shutter also had no more lag than the DSLR, and if it still had the same interchangeable lens mount, and the same sensor, and if because of the difference the camera was even smaller and lighter and less expensive, I just might be interested.
One advantage to this scenario that I don't think has been mentioned is that it would be like having mirror lockup (no mirror vibration) on every shot.
But I think it's going to be a long while before LCD technology is as good as all that, if it ever really gets there at all. In the meantime, I'll enjoy my DSLR (and my compact P&S when I don't want the DSLR's size and weight), and you can choose to settle for what you get from your C-8080's little Fisher-Price sensorette, even on your most important shots. And if what you get from your C-8080 is good enough for you and your customers, then that's all that really counts, right?
But if you're not sure whether you've made the right choice, be sure to bash and troll DSLR users at every opportunity, to help you feel better about your choice.
