I do not own this lens, but I do have the smaller 210mm version. If you want it for macro or close up it will work just fine. For infinity focus there are much more appropriate lenses in the 300mm focal length. But based on the 210mm version which almost covers 8x10 I suspect the 300mm version would cover. But the lens is designed for the range of 1/3 to 3x life sized. It's not going to be at it's best much outside that range.
