only inherited the 100mm ƒ/2.8 macro from Minolta, whose design originated in 1986. The lens is capable of a 1:1 reproduction ratio, with focusing features that make macro work much easier.
The lens was designed to cover the entire 35mm film frame, thus it has no problem working with APS-C sized ''subframe'' digital camera bodies. On these cameras, the lens will produce an effective field of view of 150mm.
