Tamron 28-75 is almost the same as my kit lens 18-55 m i right to say so?
Zoom lens. But Tamron give me better aperture value compare to kit lens hence slightly better then kit lens in portrait shot.
Ic, so lens with focal length 200mm or more = tele zoom?
go look at this website the table describing lens categories...
