My view on this...
My reservations to digital cameras is due mainly to three things - high initial setup cost, improving sensor technology, and size of sensor chip.
High cost. That's the biggie, I find. I have just witnessed a new photographer making his first (and very expensive) purchase in a Tandy and realising that it was not such a good buy afterall. I think he regrets it a little. I don't have that sort of money to fling around. Even if I did, I would be better off purchasing better optics.
Like Viewfinder has commented, 5MP maybe acceptable now, but down the line (in the space of 6 months or less) we can see better MP values in the digital cameras. Adopting the Murphy's Law (you know, that law about computer microprocessor getting faster within a few months), the situation for digital cameras (to me) is really unstable.
Size of sensor chip. I find the costs of premium optics to be quite prohibitive already. If I use my existing 28-135mm on a, say, Tandy, I will be getting a multipled focal length. That is probably good for longer focal lengths, but on the wideangle side, it will become hideously expensive. You may even have to consider purchasing extreme wideangle lenses to compensate the multipled effects.
Of course, anyone can argue that we can all troop down to a camera shop and do a MO of EOS1DS. Full sized chip (equal to 35mm so no worries about mulitpler effects) and great MP (11+MP). But who can really afford a EOS1DS (then again, I might be wrong)?
I'm not going to get into the argument about storage of images and negs and trannies (my wife and I bicker about it constantly), as others can make their explanations and comments better.
My only concession to digital photography is purchasing a Nikon Coolpix 5700 and using it in tandem with my film-based cameras. What do I do with it? I use the digicam to recce places that I want to shoot in film or tranny. I bring home the digipics and look at them in my laptop. I'll scrawl all over the images digitally and make notes for myself before I go out to take the pictures again.
It may seem a bit strange and exhausting, but I like it that way.
My two cents' worth. Dun flame hor. :rbounce:
