If you believe that a Nikon D200 produces out of focus images then you
are just stupid or gullible.

So basically some lenses and an old flash are all that tie you
to Nikon. In other words, you are free to choose Canon, Nikon,
Pentax, Sony, etc.

Any and all dSLR will create very good images. The differences
between them in image quality (maybe excluding Sigma's Foveon
sensor cameras) is mostly in the very high ISO settings (ISO 800,
1600, 3200 ...) and even the worst ones are much better than high
sensitivity film.

So basically the question boils down to:
- what feels good in your hands (I, for example, need a battery
grip for my big hands for comfortable shooting)
- Which setup of buttons and menues are best for you?
- Do you want a second control wheel (I wouldn't dream of buying
a camera without one, now that I have experienced one with
that feature)?
- do you want/need an LCD like every analog camera used to have,
or is it OK to use the main monitor to see/change settings?
(Since I often shoot in very dark circumstances, the LCD with
it's gentle orange backlight is much more appealing and eats
less battery power, too)

Decide along these and similar lines.

Then go out and buy the *very* *best* *lenses* you can possibly
afford. Rob a bank, aeh, I mean, wait longer and buy only a
fast (and a steal for the price) 50mm fixed focal length lens,
if that's all you can afford.

As you can see by looking at the reviews at http://photozone.de,
lenses deliver less resolution than the sensors can resolve,
except for the center at usually f/4-f/8. No matter how good
the camera, your lens makes the image!

Do not buy cheap, cheap lenses degrade your expensive dSLR to a
4MPix or less camera.

> saw that the Cannon 5D totally blows away all of the Nikons, except

The 5D shows up problems even in very expensive and good lenses,
since it records the borders as well. On the other hand, the 5D
has less center resolution than most crop cameras (due to larger
pixel size and huge sensor size), so lenses that are not perfect
in the center may actually perform better on the 5D.

Well, if there is that much of a difference is it not stupid to have a
new D300 not being full frame when Nikon's major competitor has a
camera only a few hundred dollars more that is full frame?

Aren't we somewhat dependent on how well and how fast a camera
focuses? Unless we do it ourselves, whatever the camera does is what
we get. In the pictures of the bears, where the "hairs" in the 5D
pictures were in better focus, or maybe it was the extra megapixels)

There was a comparison picture shooting up into a tree. Ken says the
original picture was 44 inches. So was the piece he showed, just a
tiny piece of a large picture or was that the entire picture shrunk
down? As you can see I am very confused especially after Ken
recommends the D200 over the 5D unless you need very large pictures or
extreme wide angle lenses or you always use a tripod.

The Nikon D3 is $5,000. How can you compare that to a $2,200 camera?

Actually, this is important to me because I have an F5. What happens
to DX lenses on the F5?. Between new DX lenses not being great on the
F5, not being able to use the SB28 with the D200 or D300 and all my
lenses are AF not AF-S, am I gaining that much by staying with Nikon
or could I sell everything on Ebay and get used Canon compatilbe
accessories, if there are any for the 5D.

I get the feeling that Rockwell is doing the right thing but not
explaining it well enough for us not so expereinced.

the d300 competes with the 40d. it's a little more expensive, but it
also does a lot more, including 8fps and live view *with* autofocus.

the 5d is over two years old and will probably be replaced some time
next year but that's just rumour at this point.

because if he made the appropriate comparison, he couldn't claim canon
was perfect like he always does. the full frame d3 is up against the
1.3x crop 1d mark iii.

the reality is, both nikon and canon make excellent cameras and lenses.

they vignette, except some dx lenses *will* cover the full area at some
focal lengths. the d3 can switch into cropped dx mode, but since
there's 12 megapixels for the entire frame, only 5 will be used in crop
mode. still, the result is going to be very good, and much better than
say a 6 megapixel d40, d50 or d70.

of course, there's no requirement that you buy dx lenses; almost every
nikon lens made in the last 30 years will work.

sb-28 will work in auto mode with its built-in sensor. what it won't
do is ttl with a digital slr, and those use a pre-flash that some
people don't like, so you might even prefer using the sb-28.

they'll work fine on any nikon camera including the d300 and d3. only
with the d40/d40x will they not autofocus, although metering will still
work.

if you feel the 5d better fits your needs, you might consider
switching, but so far, i don't see a compelling reason. you already
own nikon lenses and a flash that will work.

Really? How do you work that one out?
With similar pixel density, I have little doubt that in crop mode, the
result will be very similar to 6mp APS-c sesnor dslrs.
