I just bought a 105 Micro f2.8 AF. I did not notice it was not a D lens when I bought it. How will this affect flash photography? Should I sell it and get an AF-D?

I think I have found the answer myself. I quote from Ken Rockwell.
"If you are buying used lenses on a budget you can get the earlier non-D versions cheaper, and if you are considering updating a non-D lens to D, don't bother unless you shoot a lot of fill-flash.
In fact, the instruction manual of the 105mm f/2.8D AF Micro-Nikkor cautions that the D feature of the lens can lead to the WRONG EXPOSURE unless you keep your flashes at the same distance from the subject as the film, which is a real obstacle to creativity."
I will be using mine to photograph gems and minerals in a light tent with multiple speedlights at different angles, so I do not anticipate any major issues.

I would presume the D measurement is only useful when the camera is metering for a speedlight on the camera (the built-in or one in the hot shoe). Once you add multiple external lights at unknown distances and firing from all angles, they must mess with the exposure more than the camera knowing the camera-to-subject distance. You must have to set a rig like that manually or by customizing the flash compensation on each light.

I use the pop up flash in commander "--" mode and the flashes in TTL. Hmmm, I see the problem. MF lens with no communication with my camera. I believe I will get better results in manual, and so will try that this weekend. I was not getting very good results, mostly underexposure. I am glad you brought that up. Thanks! I am so rusty I forgot to use manual mode. I have used it before, so its familiar to me.
I will also probably use my SB-900 in commander mode, with my sc-28 TTL cord on one of the little speedlight stands to move it off camera. I will use it pointed directly at the gem, the lens covered in bubble wrap to diffuse the light as another Nikonian suggested in the macro forum. I want better individual control of my speedlights.
This is a work in progress, and I'm sure the 105, even non-D, will make a huge difference in my photos.

D/G lenses do take camera to subject distance when calculating exposure. I guess a question that I have to ask you is how much flash work do you do with macro. I know I have done a little, off camera, using the old GN, distance, calculation...and then I bracket like crazy.
My Micro 105D is pretty good, and the only difference was the addition of the D-chip vs. the non-D version.
I remember a member did a test of the 50mm f/1.8 using both D and non-D versions using flash and no flash. (I think it was Dave Dosch...could be wrong, I'll need to check after lunch and will update.) Basically, there was a slight difference in the D with flash but the non-D were excellent, too; a testament to Nikon's flash technology.
Update: I found the thread here unfortunately, Dave is no longer an active member, and his images were not posted to Nikonian servers; they were linked in from his image repository (whatever that was). Sorry.
Personally, I wouldn't worry too much about it, unless you can get a great price on a D version.
Good luck and YMMV.
