Sigma
today announced two new lenses designed specifically for digital SLR APS
sensor size. The 18 - 50 mm F3.5 - 5.6 DC and 55 - 200 mm F4.5 - 5.6 DC
lens can be made considerably smaller and lighter because they are designed
to produce an image circle specifically large enough for an APS size sensor
(all current digital SLRs except the Canon EOS-1D/1Ds and Kodak DCS-14n).
Both lenses are notably lighter and more compact than 35 mm equivalents.
Used on the Sigma SD9 or SD10 these new lenses would provide an equivalent
field of view of 30 - 85 mm and 93 - 340 mm respectively.
