>>4339176>They were the chinkshit of the erafun fact, some of them still are, while the actual Chinese are advancing hugely.
made-in-Japan Sigma and Tamron lenses, at least the ones I've tried, all have much worse quality control than Chinese (TTArtisan), Korean (Samyang) and made-in-Thailand Nikon lenses I've bought. I have never had to exchange three different units of the same lens to get a "good sample" even with Chinese lenses.
Sigma lenses I've tried include the 50mm f1.4 EX DG HSM, the 150-500mm f5-6.3, the 12-24mm f4 Art and maybe a couple of others. Tamron lenses include one of the older 90mm Macro versions (the one with a snapping-ring AF/MF switch) and a 24-70mm f2.8 DI VC USD.
how Sigma boasts about its "famiry-owned made-in-japan quarity renses" and how Tamron maintains huge webpages about its so-called "craftsmanship" or "monodzukuri" with a straight face is beyond me.
