It's an exercise in elegant engineering.
One of those plates is an entirely new assembly, not seen in any camera before. It therefore has development costs. The electromagnets contain expensive metal and need to be manufactured as separate assemblies and then constructed onto the plate. Then the sub-assemblies need to be joined toether. Elegant, indeed, and undoubtedly less mechanically complex than the aperture simulator mechanism. But much more complex in other ways and undoubtedly more expensive, at present, than a few pieces of stamped, painted steel. ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
