A macro lens system includes, in this order from an object side: a positive first lens group; a negative second lens group; a positive third lens group; a positive fourth lens group; a positive fifth lens group; and a negative sixth lens group. The first lens group is constituted by three lenses. The second lens group, the fourth lens group, and the fifth lens group are independently moved in the direction of the optical axes thereof when focusing from an object at infinity to an object at a most proximate distance.

Macro lens system and imaging apparatus

An objective lens comprises a housing, an iris diaphragm and a plurality of lens groups. For focusing the objective lens while minimizing the variation of the image angle at least two lens groups are adapted to be moved relative to the housing. The one lens group is arranged in front of the iris diaphragm. The other lens group is arranged at least partially behind the iris diaphragm.
