On film, or digital? I think film is much less grainy than digital. It does
much better in low light.

That's not the conventional wisdom. Good DSLR's have very little
graininess at ISO 800. Really good ones have little even at 1600 ISO.
I'm wondering if you're confused with long exposures leading to noise.
CCD's have some "inherent" noise that gets brighter the longer the
exposure (and always on the same spots from photo to photo). This was a
bigger problem for digital non-SLR's. The solution was to take _two_
exposures: One the "actual" exposure, and the other a totally dark one
(shutter doesn't open) of the same time. Then subtract the noise.
Most good digital cameras have a mode where it does all this for you.

No, it was a problem for cheap digital non-SLRs. For decent digital
non-SLRs, they solve it the same way.
And really, "SLR" is a misnomer at this point. The little cameras with the
LCD on the back and no viewfinder at all are "single-lens". I'm not sure
what the "reflex" part means, but all cameras nowadays have a single lens.

Yeah, exactly.
In any case, I've noticed more grain in the digital pictures than the film
pictures. Can't say why, other than the film pictures were all printed
before being scanned, so that might have something to do with it.

I know. What I meant was that the actual noise was worse in digital
non-SLR's (assuming you don't do frame subtraction on either). With some
good digital SLR's, you don't get too much noise for equivalent
exposures even if you disable dark frame subtraction.
As for higher ISO noise, I don't know from personal experience - I was
just repeating what I've read. I was not into photography when I had a
film camera, and probably all my film was ISO 100.

True enough. I don't think I ever shot more than a roll or two of 800.
Usually 200 or 100. Occasionally 25 if I wanted some really long exposures.

Ah, was about to ask if you considered the Canon before your purchase :-) I
just bought the Canon 450D, and for the same reason didn't need to consider
any comparison with Nikon unless I wanted to also buy a bagful of new
lenses!

> Just normal stuff. A 28-300 zoom,
I need a lens like that, ATM I have something like a 17-85 that I use most
of the time, then a 75-300 for telephoto stuff, it's sometimes annoying to
have to keep swapping.
> a 50mm,
I have the Canon 50mm F1.8 and it really is superb value for money,
especially in low light situations or when you need a massive background
blur. You need some ND filters to get the most out of it in bright sunlight
though.

It means there is a mirror in there.

That's one good reason for me to go for Nikon also. The other one is
ergonomic - most Canon SLR's have the trigger pointed more forward than
most of Nikon SLR's and that makes a whole different position for my
upper body, resulting in steadier position with Nikon than with Canon.

We did, actually, but we had to factor in having the lenses. Canon wasn't
*enough* better...

Oddly, the way the strap is connected to the Nikon, the camera tends to hang
at a 45-degree angle with any lens more than a couple inches long, leaving
the bottom edge to dig into your chest if you let it hang. I guess it's hard
to fix it, at least without putting (say) swivel mounts for the straps or
something.
