I've taken a few test shots of clouds with my D70s and I notice that the
four corners of each photo is black. Why is this, is something wrong? The
D70s is only a week old.

Camera set to auto
Lens: 18-70 (pictures taken at 18mm)
iso 250
white balance A

polarizing filter Hoya 67mm PL-CIR
UV filter Hoya 67mm (uv0)

image quality
nef raw
jpeg fine
jpeg normal
jpeg basic
nef+jpeg

All five shots have blackening at all four corners

Your post implies that you are using BOTH the UV filter, AND the polarizing
filter together.
If so, then this would certainly lead to vignetting as you
describe...expecially at the wide end of your zoom.
If you're using a polarizer, you should mount it alone...NOT in addition to
the UV.
Use one or the other.
Not both at the same time.

With some longer lenses and extra thin filter mounts, you can get away with
mounting two, but the polarizer should do away with the need for the UV.
It's of no benefit...

Wide angles and multiple filters sound like a guaranteed recipe for
vignetting, which is what you're seeing. You can take the filters off, and
the problem will likely go away. If you really need both filters, you can
try a longer focal length, and/or a smaller aperture.

Try at a slightly longer focal length.
You may be getting some vignetting from the two filters; try with none
or just the polarizer. You shouldn't need the UV filter anyway.

So obvious, the answers to such a dumb question. Nice to know that when you
need an answer you just have to ask. Thankyou.

Next Question, I've read that many nikon lenses produced before 1977 are
compatible with the D70 body if a $35 conversion is used to avoid damage to
the body. Also, newer lenses (less than 25yrs old) work just fine with the
D70. Is this also true for the D70s and how can you tell how old a lense
is?

May be stupid remark, but this happened to me:

The hood was not mounted completely, I had to use lots of force to put it
into place. I was afraid of breaking some plastic the first time.

Old lenses have pins and will damage the body on the outside. This happens
also to newer analogue bodies.

Wrong lens, or defective lens. Cropping in post will take care of those
pictures you have already taken.

If it is vignetting which is exagerated by filters Nikon Capture 4 does
a great job of removing vignetting from 18mm focal length of the 18-70
Nikkor DX lens.

It is vignetting caused by using too many filters. Another contributing
cause is using filters which are too thick for wide angle shots. You don't
need the UV filter with a polarizer anyway.
Also, you need to buy a polarizer that is designed for use with wide angle
lenses.
