Yep. At this point Sigma is going to be designing all its premium lenses with electronically controlled aperture. The change for each lens mount they support is minimal compared to designing complete mechanically operated aperture just for one manufacturer (one with small sales volume, at that). Although it isn't clear from the photos I've seen so far it certainly looks to me as if the new D-FA 50/1.4 has no diaphragm actuation lever. -- Mark Roberts - Photography & Multimedia www.robertstech.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
