Guys...correct me if i am wrong. Gonna share what I understand from reading here n there so far. Take it with a pinch of salt as I might be wrong.
TST sells mainly water goods, whh means as good as no warranty at all in SG and HK. This is why they are able to press the price to such a low level. (approx 550+ range)
There might be more expensive HK "version" which comes with Sigma HK warranty ( approx 650+ range). This warranty is sort of honoured by Sigma SG and you can basically do stuff like free calibration etc).
Finally its full warranty by SG for those who are stucked here in SG and wanna test out their lens (approx 750)
