Weak gravitational lensing has the potential to select clusters independent of their baryon content, dynamical state, and star formation history. We present the first shear-selected sample of clusters, detected in early data from the Deep Lens Survey (DLS), a deep BVRz' imaging survey of 28 square degrees. Cluster redshifts are determined from photometric redshifts of members and from lensing tomography, and in some cases have been confirmed spectroscopically. DLS imaging data are also used to derive mass-to-light ratios, and upcoming Chandra and XMM time will yield X-ray luminosities and temperatures for a subsample of 8 clusters. Thus we can begin to address any baryon or luminous-matter bias which may be present in current optical and X-ray samples. When the DLS is complete, we expect to have a sample of 100 shear-selected clusters from z 0.2-1.
