What do DC EX and HSM mean?
What do DC EX and HSM mean? I found this lense:
http://cgi.ebay.com/Sigma-30mm-f-1-4-DC-EX-HSM-Lens-Nikon-Mount_W0QQitemZ180290379317QQcmdZViewItem?hash=item180290379317&_trkparms=39%3A1%7C66%3A2%7C65%3A15%7C240%3A1318&_trksid=p3286.c0.m14
on ebay. What do those abbreviations mean? Are they good, bad, or irrelevent?
DC = Digital Camera – optimnised for DSLRs with less than full frame sensors- for example APS-C sized sensors
EX – does not not really stand for anything, SIGMA use it to denote their premium lenses.
HSM – Hyper Sonic Motor- this is the fast and quiet autofocus motor built into the lens- each manufacturer has their own name for the same thing – such as Canon’s USM
