Pentax @ PMA 2007
Craig February 28th, 2007
Pentax have announced a couple of new lenses - smc PENTAX-DA 16-50mm F2.8ED AL [IF] SDM and smc PENTAX-DA* 50-135mm F2.8ED [IF] SDM. Designed exclusively for use with its digital SLR cameras, these zoom lenses are the first models of the new high-performance smc PENTAX-DA* lens series.
The SDM system is a new autofocusing motor that provides smoother and quieter AF through the inbuilt supersonic motor. This will only work on the Pentax K10D after a firmware upgrade - on other Pentax DSLRs, conventional AF will still operate.
These new lenses are also sealed against dust and moisture.
