The nucleus 52Fe with (N=Z=26) has been investigated using intermediate-energy Coulomb excitation in inverse kinematics. A reduced transition probability of B(E2;01+→21+)=817(102)  e2  fm4 to the first excited 2+ state at 849.0(5) keV was deduced. The increase in excitation strength B(E2↑) with respect to the even-mass neighbor 54Fe  (B(E2↑)=620(50)  e2  fm4) agrees with shell-model expectations as the magic number N=28 is approached. This measurement completes the systematics of reduced transition strengths to the first excited 2+ state for the even-even N=Z nuclei up to mass A=56 .
