It is also a powerful probe of the connec tion between the visible components of galaxies and galaxy clusters and the ir dark matter halos. The past few years have seen advances in weak lensing measurements with ongoing surveys such as the Dark Energy Survey (DES)\, t he KIlo-Degree Survey (KIDS)\, and the Hyper-SuprimeCam (HSC) Survey.\n\nIn this talk\, I will begin by describing the HSC survey\; HSC's powerful com bination of depth and image quality makes the HSC survey unique compared to other ongoing imaging surveys. I will then describe several lessons learne d from completed and ongoing lensing science analyses with the HSC survey W ide layer. Finally\, I will conclude with challenges that must be overcome in order to realize the scientific potential of even more powerful upcoming surveys\, with a particular focus on scientific preparation for the Rubin Observatory Legacy Survey of Space and Time (LSST) carried out within the L SST Dark Energy Science Collaboration (DESC).
