Looking for a new zoom lens between 70-300mm f2.5 to 3.5 give or take but i need to know which other manufature make lens that fit canon and what do i look for on a lens that makes it compatible.
there is no lens with that wide of an aperture that goes to 300mm. you can get a sigma 70-200mm at a constant f/2.8 though. this is a very good lens and costs $759. thanks and hope it helps.
The Sigma 70-200mm 2.8 is my work horse lens!!
