have to agree with the old Sigmas having sub-par build and IQ than the signature Canons and Nikons. nakagamit na ko sometime in 2009-2010 and parang laruan lang ang feeling nya. but i did some checking lately and found out that they have moved to a new direction and are now producing high quality lenses that, as SLR Lounge editors have put it, are close to surpassing signature brands and have move on to compete with the likes of Zeiss.
im tempted to rent or borrow a 17-50mm f/2.8 OS for canon body. gusto ko try yung fixed aperture to justify my need for an all-rounder that can take shots in poorly lit locations.
sino ba naka sigma pa dyan? paki inggit naman ako haha
