Providing a large aperture wide-angle lens having high optical performance with sufficiently suppressed spherical aberration and sagittal coma flare, and an imaging apparatus using the lens. The lens including, in order from an object, a first lens group having positive refractive power, and a second lens group having positive refractive power, the second lens group being movable for focusing and including a 21 lens component having positive refractive power, a 22 lens component having negative refractive power, a 23 lens component having positive refractive power, and a 24 lens component having positive refractive power, and given conditions being satisfied.
