I was looking for a longer lens for the D90, I have a 70-300mm VR lens, Nikkor just now.
I was told that I can't use some of the Nikon range lenses becuase the D90 is a F4.5 but I can't use anything like a F2.8 or F1.8, anything lower than F4.5 will not work on the D90............
But I read some posts on the forums and people advise others to get a Sigma F2.8 or whatever so if a Sigma can work, why can't Nikons or am I getting wrong meassages here?
I know there's something to do with the Pro cameras and then the mid range cameras and then the low end cameras.
Then you get someone telling you all Nikon lenses will fit and work fine with the D90, even the pro lenses. This gets cunfusing.
Thanks for any help in advance.
