"It is important to be precise with language in order to understand and avoid misleading other readers. Here's how I suggest phrasing it: "Once the 300mm lens is mounted on the 450D, you would achieve an angle of view that is equivalent to a 480mm lens mounted on a full frame camera."


LOL,'six of one, half a dozen of the other', but I will keep this in mind, thank you. []


As for the Sigma 150-500, it does have stabilization, it is Sigma's version called Optical Stabilization.


Thanks for theopinions/suggestions everyone.
