The DirecRt: DRardiivael vaSluSeMs Tf:oTacnugsenstiyalsvtaelumes is more than up to the task for both stills and movies. DDSM has the capability to position the large, heavy optical assemblies required by large-aperture lenses with pinpoint precision, offering advantages for manual focus as well as autofocus.

All of this works in harmony with the XA element and a 9-blade circular aperture to create gorgeous bokeh too. Pro grade control and reliability Sony's standard lens sealing is augmented by a lens mount seal that maximizes resistance to dust and moisture for reliable operation in challenging environmental conditions.* Additional details like rubberized rings that are easy to operate in low temperatures, a zoom lock that prevents unwanted lens extension during transport, and a hood lock button, all add up to professional control and convenience. * Although the design is dust and moisture resistant, absolute protection from dust and moisture is not guaranteed.
