From Our Engineers...
The B1DX-L assembly was designed to meet our high standards of functionality and aesthetics. It was an especially challenging design considering the rather wide positioning of the 1D X side ports.
Over the past year, Really Right Stuff has significantly increased its implementation of Finite Element Analysis software. FEA allows us to design structural components, like the B1DX-L upright section, for the best possible combination of weight and strength. In one of our more exhaustive analyses, the B1DX-L plate assembly performed better (in terms of body deflection under load) than some of our more current pro camera body L-plates. We are confident that users of the B1DX-L plate will not have to compromise their work to accommodate its new design, but rather will find that it simplifies and greatly enhances their work.
