Hi folks,
Btw, if we buy tamron/canon lens from overseas and its on int'l warranty... Will the local svc centre actually support the warranty?
Exploring my options since it seems cheaper from overseas especially for tamron 
I certainly have a better idea now when selecting my next lens... Appreciate the tips and sharing...
Will ponder in the next couple of days. Hopfully to nail it down soon :D
Cheers!
Thanks for all the comments everyone....
I sort of shortlisted the 18-200/270mm for convenience and avoid having to bring 2 lenes during holidays. Understand will need to compromise on IQ at times....
Checked out the pictures and reviews on the website... Canon seems to have better...
I am planning to upgrade from my Canon 550 kit len (18-55).
I have narrow down between Canon 18-200 vs the new Tamron 18-270pzd. As it seems to have the range for holiday travel, landscape and family outings/indoor.
In terms of sharpness and IQ, which will be better?
And which has better...
