Alan thanks for your response.

>Indoors, where the flash is the main light source, you should

I wondered about this. When I was getting preflash 2 days ago it was brighter and there was more of a need for fill flash.

Is there a setting to changes this in camera?
I am hoping that my load save settings blunder changed something. I accidentally loaded my wildlife U1 settings into the main camera but I thought I changed it back.

The image I presented was with pop camera flash. My external flash has a mode button which lets camera control it or puts it in manual. There is no specific setting to control TTL or TTL-BL.

Also for more info when I shoot with F stop below 5.6 and especially if iso is set at 200 the exposures are more correct.

Shouldn't I be able to manual expose at f-stop 10, iso 100 and shutter speed 200, especially with an external flash?

>An unrelated question; do you really need -18 AF Fine Tune for
>this lens?

I bought this lens used 3 days ago as I don't have a portrait zoom lens. I wanted the shallower depth of field of 2.8. After taking some portraits I thought images were soft and put it through a focus test and and found significant back focusing. Depending on focal length and distant to subject the AF fine tune needed to be -16 to -19. I thought -18 was a reasonable compromise.

Only 2 out of 5 of my other lenses "needed" fine tunining, but fine tuning was < 5 for these lenses so I don't think there is a serious focusing issue with the camera.

I have 2 weeks to return lens if I am not happy. I am in the process of making up my mind. I paid about $300 and the comparable new lens is well > $1000. Preliminarily I think I will keep lens and let camera correct focus. I'll see how today's shoot goes but now I will also have to be dealing with manual flash settings which I have no experience with. BTW the flash underexposure issue is not lens dependent as I tested this lens on D5000 and tested flash on D7000 with multiple other lenses.
