  The electromagnetic form factors provide important hints for the internal
structure of the nucleon and continue to be of major interest for
experimentalists. For an intermediate range of momentum transfers the form
factors can be calculated on the lattice. However, reliability of the results
is limited by systematic errors due to the required extrapolation to physical
quark masses. Chiral effective field theories predict a rather strong quark
mass dependence in a range which was yet unaccessible for lattice simulations.
We give an update on recent results from the QCDSF collaboration using gauge
configurations with Nf=2, non-perturbatively O(a)-improved Wilson fermions at
very small quark masses down to 340 MeV pion mass, where we start to probe the
relevant quark mass region.
