I visited a camera exhibition show two days ago. When I walked to the Sigma area, I have chance to play some of the high-end lenses. What impressed me came from two new products which not yet released in Hong Kong market. They are 135-300mm f2.8 HSM and 80-400mm f4.5-5.6 with IS function. If the 80-400 is available for KAF mount, it would be the first IS lens used with Pentax AF camera. It would be great if the IS function is also valid for Pentax manual body. The 135-300 is very heavy but the focusing speed appeared reasonably fast with EOS body. The f2.8 constant aperture is great for such tele zoom but uses 90mm front filter (if memory correct).
Sigma now offers Pentax users some products which are not available in Pentax line (at least in near future). _____________________________________________________________ Weight Loss products, Herbal Viagra, and much more!http://www.VitaDepot.com _____________________________________________________________ Select your own custom email address for FREE!
