Tokina 12-24mm Wide Angle Lens questions….?

So i just got the Tokina 12-24mm Wide Angle Digital lens for my new D80 Nikon camera. I bought it with a 77mm threaded circular UV filter to minimize glare. the lens comes with a Hood. Can i use the Filter which screws into the front while i have the hood attached? or do i need to remove the hood to use the lens? Also, the manual for the lens recommends i use an external flash like an sb-600 because it says the built in wont work effectively with this lens. Why?
I got the UV filter to protect the end of the lens itself, as well as to minimize glare and ghosting.

I own a Tokina 12-24mm. Good lens.

1) forget the UV filter. It actually will cause more ghosting and reflections, reducing contrast. Shoot without the filter and use the lens hood. Put the lens cap back on when you’re not shooting, to protect the lens.

2) the only filter I routinely recommend is a circular polarizer. However, the lens is so wide, that a circular polarizer’s effects at darkening skies are not so effective, except when the lens is zoomed in.

3) other filters are more specialized–like graduated neutral density filters–and are designed only to be used to create a specific effect, like holding back the brightness of the sky so you can get the foreground into the right exposure. They are not “leave on your lens” kinds of filters.

4) the best way to minimize glare and other issues: use a lens hood. Don’t shoot directly into light. Be aware of any light hitting the front of the lens from the side.

5) the external flash covers a wider area than the built-in flash, plus you’re likely to get a shadow from the lens itself into the picture with the built-in flash that you won’t get from a flash in the hotshoe.

6) Stopping down to f/8 or better will get you images without the chromatic aberration; shooting wide open will get you images with that purplish chromatic aberration in areas of high contrast (like branches against a light colored sky, for example).
