Canon has released a new iteration of the same old EF 28-90mm lens that’s been around forever. The Canon EF 28-90 f/4-5.6 III combines the same optical and electronics technology as the EF 28-90mm f/4-5.6 USM but is equipped with distance metering information. This feature provides compatibility with the E-TTL II flash system which takes the lens distance information into account during autoflash. (*yawn*) More info on Canon USA’s product page.
