Nikon D70 + Tokina 12-24

Is this lens incompatible with the built in flash? I keep getting a
shadowy half moon at the bottom of the picture.

Additionally, having played around : this dark area only occurs with
the lens between 12 & 18 mm and only with flash. So not the lens
obstructing the light since then I'd get the dark area with the lens
fully extended at 24 mm?

Well the angle of view is wider at 12mm so more likely to include the area
in the lens' shadow. The 24mm view may not be wide enough to see the
shadow. The other problem is the D70 built in flash doesn't cover the
whole frame with a 12mm lens. Can't remember off hand what the limit is
but its not 12mm.

I stayed in the same position photographing the same object. If it was a
"shadow" wouldn't it be in same location in the real world?

If the shadow was at the top, I would say it is due to the lens shade. I do
not have any such problem with this lens on my D70.

I have determined its the built in flash between 12-18 mm.

Can you confirm that this does not happen to you?

Yes, it will not cover that wide an area. It is limited to 24 MM. In
addition it is too low on the camera and it is the shadow of the lens you
are seeing.

Probably, some wide-angle zoom lenses are. Did you remove the hood? How
close was the subject?

Your manual probably lists some of the Nikon lenses with which you'll
have issues. Is the Nikon 12-24 listed there?

Thanks to all.

It is the wide angle setting picking up the lens obstructing the flash.

As a newbie it never entered my mind to check built in flash
compatability : a lesson now well learnt. I'm also very surprised not to
have seen this mentioned din online Tokina reviews.

Will a Speedlight 800 be ok, since its considerably higher when shoed in?

An SB-800 would get rid of the shadow in the frame. As would an SB-600 or
just about any compatible external flash.
