Wide angles and flash can be a problem. The SB-50DX comes with a
diffuser panel to cover 14mm (Which will cover the 10-20mm at 10mm,
which is 15mm effective), not sure about the SB-80DX, although I can say
that without a diffuser panel it will not cover the entire frame at
10-13mm (Can't recall if it covers 24mm or 20mm).
The one caveat is that auto-zoom may not function correctly, especially
with older flashes, so you may need to manually zoom to the 35mm
equivalent of your focal length.
The DA 16-45 is ~24mm equivalent at the wide end, so most newer flashes
will cover the frame (The built-in flash on the D will not however, it
only covers to 27mm equivalent, or 18mm actual)

Hi Troops.
I recently picked up a new Sigma 10-20 for my Nikons. I have had little time to
test
anything, but i did
throw it on a camera for a minute yesterday afternoon and shot some indoor tests.
One thing i noticed is the outside part of the image is not as well lit as the
middle
portion. I s this an
inhernt problem with really wide angle lenses and flash(or difficult light) or is it the
flash with not
enough side coverage.
Flash used was the 80DX for those familiar with same.
I only viewd the files on the LCD screen, not on the computer yet. If this is
normal for
this type of lens,
how does one fix it to get an overall balance of light.
Sorry for what is probably a stuipd request for help. I'm just not used to
really wide
lenses and flash
etc. I have used the DA 16-45 at 16mm with flash and it seems to light up well enough, or
atleast
nothing bad that i can see.
I have until Saturday to return it if its not working properly.
