  We study the electromagnetic form factors of the lowest-lying singly heavy
baryons with spin 1/2 within the framework of the chiral quark-soliton model,
focusing on the comparison with recent lattice data. To compare the present
results quantitatively with the lattice data, it is essential to treat the pion
mass as a variable parameter, i.e., to employ the unphysical values of the pion
mass, which are used in lattice calculations. While the results with the
physical value of the pion mass fall off faster than those from the lattice
calculations as the momentum transfer increases, the extrapolated results with
larger pion masses get closer to the lattice data.
