First, film is a medium. Reala or NPH or Velvia 50 or Provia 100 will all have a particular and unique signature. Right now, we don't the luxury of installing different sensors and firmware into our digi cameras. Yes, there's digi post processing, but that's a whole different ball of wax.
Second, cameras are tools. Like many others, I haven't found a digital camera in one of my prefered form factors. Right now, we have P&S digicams and the DSLR. I have a Nikon D70, a prettty typical DSLR design.
But the DSLR it's not my prefered design. It's too large, does too much, lacks traditional controls and interfaces (cable release, PC socket, etc.)
I'd greatly prefer a FM3a-D with a full frame dedicated B&W sensor. The FM3a film counterpart is a wonderful camera. Sturdy, easy to load, small, nice VF with high magnification, and so on and so forth. Give me plenty of pixels to print high quality 11x17 and it's a camera I'd be happy to own for a decade or more.
Or, I'd greatly prefer a Leica DM or Zeise D-Ikon. Blah blah.
And while their at it, solve the sensor dust problem for us, so I don't have to worry about that. And put nice, high mag viewfinders on affordable digi bodies.
My point is that, while I do use my D70, it's bulky, has too many options, but still lacks many basic features, doesn't fit into a small satchel camera bag, and so on.
There are no affordable digi tools - yet - to match my Bessa R, 2 Leica M6TTL's, Nikon FM3a and the associated lenses. Or even my Rollei AFM35 P&S. Relatively small, sharp tools: lightweight, good viewfinders, simple and predictable meters, superb prime lens optics, produces a lovely 24x36 negative on the film of one's choice, and so on and so forth.
Hopefully, as the digital market matures, we'll see new digital camera designs apart from the digicam and the large DSLR design.
Until then, I'll continue to shoot film because the film shooting tools are better, IMHO.
