Wow, quite the handle, and as I understand it, it is a macro lens. Now I think I understood crop factors, and as I understand it, this is actually a 90mm 35mm equivalent. Is that right? In other words, this lens would have approximately the same FOV as my Nikon 105 F2.8 micro(macro). Is that right? If it is why don't they just called it a 90mm?

Because the lens' focal length and magnification is still equivalent to 45mm. The lens is still a 45, it's the sensor that changes.
 
They don't call it a 90mm because it's a 45mm. A lens' focal length is independent of the field of view it achieves with a given sensor type. For all intents and purposes, just double the lens' focal length to get an idea of its equivalent FOV on full frame.
