The weak gravitational lensing effect is of increasing importance in cosmological studies, so it is a good point at which to examine w hat can be done with the effect which is beyond the obvious. In this talk I will discuss three such avenues of enquiry: (i) the prospect of using radio telescopes for weak lensing; (ii) the opportunity to use more detailed galaxy shape information in lensing; and (iii) the combination of lensing with other cosmological probes to constrain modifications to Einstein's theory of gravity.
