Here's an interesting snippet of news courtesy of our friend Yamada Kumio. Sigma will soon introduce a new AF 15-30mm F3.5-4.5 EX DG lens, this lens is of most interest to those users of digital SLR's because it will offer them zoom lens with a decent wide angle bottom and usable 'normal' telephoto. For example, this lens on a Canon EOS-D30 would provide an equiv. range of 24-48mm, on a Nikon D1x it provide an equiv. range of 22.5-45mm. The lens comes with the hood attached and access at the back of the lens for filters.
The lens should be on the market (at least in Japan) with Sigma AF, Nikon AF and Canon AF on August 1st 2001 and soon after for Minolta AF and Pentax AF.
