Using the CLAS detector system in Hall B at Jefferson Lab, we have done a high statistics measurement of the photoproduction of K^+Λ(1405) on a proton target. The reconstructed invariant mass in the three different Σπ decay modes has been measured, as well as the differential cross section. Our goal is to understand the nature of the Λ(1405), which has been a longstanding puzzle for decades. Its peculiar mass distribution is not well understood, and studies have shown that it may posess strong dynamical components, which could be extracted from our data. Various aspects of our analysis are discussed, and preliminary results are shown.
