  The electromagnetic form factors of octet baryons are investigated with the
nonlocal chiral effective theory. The nonlocal interaction generates both the
regulator which makes the loop integral convergent and the $Q^2$ dependence of
form factors at tree level. Both octet and decuplet intermediate states are
included in the one loop calculation. The momentum dependence of baryon form
factors are studied up to 1 GeV$^2$ with the same number of parameters as for
the nucleon form factors. The obtained magnetic moments of all the baryon
octets as well as the radii are in good agreement with the experimental data
and/or lattice simulation.
