By studieng Sigma web sites, it seems this lens - unlike the latest version is NOT HSM Hyper Sonic Motor. Menaing focusing is run by the camera "screwdriver" only. Also it's not a DG lens - meaning - it's not especially designed for digital cameras. It seems that the "EX" means something like "exellent exterior" design.
According to the seller it's razor sharp, whcih is what I want. If I don't buy it I'll probaly get the new DG/HSM version, which is quite expensive. Or I may reconsider the SMC DA f/4 300mm, which is supposed to be superb - and accordingly expensive for a 4.0 lens. Regards Jens -- Treat others as you would like to be treated yourself.
