APO 70-200mm F2.8 II EX DG MACRO for Pentax and Sony HSM

Large aperture zoom lens with advanced optical performance

This large aperture zoom lens has improved optical performance and retains close-up ability with a minimum focusing distance of 100cm/39.4in. SLD （Special Low Dispersion） and ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting. The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling. It is possible to attach optional Sigma APO teleconverters.

Now this is a piece of good news lah. Sigma will do us proud and a wise step to take to intro this lens. As a third party lens provider, I salute you!! What do you know...this lens even comes with HSM ...High Speed Motor dude.... I think if couple with a 1.4x convertor should work out decent as well. Now Tamron is of course out of the list..

I do really like Sigma optics as it render pin sharp most of the time. Now with the HSM ( High Speed Motor ) , this is really really wonderful man. What's more? Inner focusing and zooming system like those of Tokina..ahahaha.. So time to safe and work harder!!
