> 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.

Fair enough. One has to wonder why there's still a mirror in there. :-)
My Sony lets the light hit the sensor, then puts the display in the
eyepiece. You don't have to screw around with a whole bunch of internal
mechanics, waiting for the mirror to get out of the way, trying to draw
fancy stuff on the viewfinder without having to do things screwy. :-) No
left-overs from mechanical days. Plus, you can do IR.
I'm still not sure how the thing autofocuses without interrupting the light.
I can only guess it's using a half-silvered mirror, and hence the
prohibition against linear polarizers.

You'll never get the same resolution with a monitor ;). For me for this
reason live view doesn't make much sense with a DSLR - although I have to
admit that beeing able to shoot movies with different lenses with the
Nikon D90 (and some Canon models) is very cool.

Your D90 can do this too, though the image is displayed on the back LCD
instead of in the viewfinder.

The main drawbacks of not having a mirror are that you cannot have a
through-the-lens optical viewfinder or phase-detect autofocus.

Actually, there are two mirrors. The big one is indeed semi-transparent.
Most of the light is reflected up towards the viewfinder and exposure
meter, and the rest goes to the smaller mirror which reflects the light
down towards the autofocus sensor. Linear polarisers can mess with
exposure because they can alter the proportion of light that reaches the
exposure sensor.

True. But then I can zoom in on bits while I'm lining up the shot to see if
it's in focus and such. My eyes aren't good enough to see that difference
anyway.
And, of course, if they splurged on an LCD with the same resolution as the
image sensor, it would be a bogus reason. (Of course, it would be silly to
do that.)

It would make a lot more sense if the LCD swiveled. I can't count the number
of pics I took with my Sony by holding it over the heads of the crowd.

Yep. Altho I find I don't watch the movies nearly as often as I watch the
photos, I *have* figured out how to get the D90 movies to play over the XBox
on the big-screen HDTV.

Yeah. The Sony I have does both, which is nice when it's bright out. And (as
I said) you can tip the LCD on the Sony so you can shoot from other angles.

Sure. I'm just not sure what the benefit of an optical viewfinder is over an
LCD viewfinder. The Sony seems to do a better job of autofocus, but then
I've had years to play with it and learn its quirks, so maybe phase-detect
is a better method.

More precisely, they'll screw up your half-silvered mirrors' reflections.
The linear polarizer is exactly messing with reflections off transparent
surfaces (i.e., prisms), which is exactly why you wear them when fishing or
driving in a car with glass windows that have reflections in them otherwise.
I didn't find the circular polarizer to have any noticable effect on my
photos, tho.

Resolution, colour fidelity, response time.

Phase-detect is generally faster, often much faster. Contrast-detect
autofocus, if implemented well, can be more accurate.
Also, contrast detect AF requires having the sensor powered up.

If you are aiming for the "deep-blue sky" look, you will want to point the
turn the polariser to match.
If you just want to see the polariser in action, look at an LCD through it
while slowly turning it.
