Thanks for the input/help. I can see that I do not want to leave any of my other lens behind.
I just kind of figured if I really needed to get better close ups using the 90mm, the pics are so nice and clear and sharp they are really good ones for cropping. Of course that can be said about the other lens also.
I do have time to save up some money to buy a straight 28 or 35mm . Then again, I think I will use what I have available.
In the meantime if any of you guys see a real good deal on one of the 28's or 35's that will work on a Nikon, let me know.

Thanks again,
Ken
