DPreview消息，适马刚刚正式发布了150-600跟18-300镜头。除此之外没有别的消息。除非适马会在三天内再开发布会，否则24 art跟14-24恐怕是等不到了……

Sigma has announced a new superzoom lens for APS-C format DSLRs. The 18-300mm F/3.5-6.3 DC Macro OS HSM takes its place in the company's 'Contemporary' linep, offering a focal range equivalent to 27-450mm. The new lens will be available next month for $579 in Sigma, Nikon, Canon Pentax and Sony mounts - the latter two will not feature OS optical image stabilization.

Sigma has announced a pair of new telezoom lenses. Both described as the '150-600mm F/5-6.3 DG OS HSM' one carries Sigma's 'Contemporary' branding and one is positioned in its 'Sport' lineup. The sports version is dust and splash-proof (only the mount is sealed on the 'C' version), and both lenses boast new versions of Sigma's 'OS' optical image stabilization system. Under the hood though, their construction is significantly different.
