Because my mom said I talk too loud?

Hey I can't help that, I was trained that way...

Yes, you talk too loud. The other part of the answer is that the
loudness is only part of what you learned at Mom's School of Spin.
The problem is that you do it so poorly that Rockwell gets a free
pass, since your own words damage your credibility. Perhaps you
should ask Mom for a refund. Or take a refresher course.

The D200 is 120 better than the D80.

Actually, no. It doesn't work that way. Cameras aren't compared
the same way that you'd compare print resolution. Your calculation
would have us believe that the D200 is 150% better than the D80
((200-80)/80) when in fact it is 525% better ((200^2-80^2) / 80^2).
So if the D80 is worth $1000, the D200 is a real bargain, since it's
clearly worth more than $5000.

But conversely, the D80 sensor is 3872x2592. The D200 sensor is
3872x2592. If you compare sensor sizes, you get 10036224/10036224, or
100%. Therefore, the D200 is 100% better than the D80.

That is 100% equal or 0% better.

I can't find in the specs from Nikon where it says the D80 has mirror lockup.
Also, both the D80 and the D200 sport a 10.2MP sensor 3872x2592 pixels. Seems
the same to me.



The D80 has no mirror lockup mode. What it does have is a fixed 0.4
second shutter delay which can be set when using the camera on a
telescope or microscope (according to the manual this is why they
provide the delay). The shutter opens 0.4 seconds after the mirror has
flipped up.

It also has 2, 5, 10 and 20 second options for a regular self-timer with
no mirror lockup.

Interesting theory, but the D200 is older, so the D80 is 100%
better, unless you have a workable conspiracy theory implicating
Nikon. I tend to think Nikon innocent, with the D80 being a major
advance for all photographers, since it's moving in the direction of
allowing DSLRs to produce in-camera the kind of intense azure that
you and so many other photographers prefer. Quelle cool tool!

So you're saying that it's not the D200's fault that I blue out the
highlights on that Seattle photo?

I think the sentance above says it all :-) "I" did it.

For comparison to see if you need the D200 over the D80, perhaps.
But
there are factual errors, such as the sensor being the same as the
D200 (it is not), no mirror lockup (it has it), etc.

Didn't he say that they both had mirror lockup, but the D80's was
more limited, being that it was really just for sensor cleaning?

While the D200 can hold the mirror up for an extended period, the
difference is merely a period of time. The purpose is to eliminate
mirror slap vibrations, and both do that exactly the same way.

I don't know what the D80 does, the D200 has 2 options, a 1/4 second
delay or a two-click option where the second shutter click fires the
shutter. 1/4 second might not help much for a long or macro lens swaying
on a tripod.

True mirror lockup means the mirror is locked up out of the way before
a lense is even attached so that a lense with a protruding rear
element does not get hit by the mirror when it moves, then stays up
AFTER the exposure so the mirror doesn't fall on the rear of a lense.

The D200 does not offer this option. I'm pretty sure the D80 doesn't either.

This isn't a big deal these days as most lenses don't protrude into
the mirror chamber.

The comment about the D80 is only for sensor cleaning is VERY
misleading. Also in the comparsion chart he says "no" for mirror
lockup, which is wrong since the D80 clearly does have the same delay
lockup as the D200.

Yes, which is bullsh!t.

I bet you wished you knew just what you are on about.
