The ε-Extender is a high performance extender, composed of 7 elements in 5 groups. Coma aberration is corrected by a special Takahashi design. Even when the focal length is enlarged 1.5 times, under optimum imaging conditions a star image equal to or better than the direct focus star image can be obtained. Across all models, optical performance is 2 microns or less (RMS-SPOT) in the center and up to 8 microns at the edge of a full frame sensor.
