Hi everyone,

Im juz a beginner, and would like to ask if anyone can help...

I bought my Canon 600D twin lens kit, which including the 18-55mm and 55-250mm lenses. However im getting a bit annoyed by keep changing lens and thinking to get the all-in-one lens...

There are two which im considering at the moment but not sure which one should I get...

1st: Tamron 18-270mm IS lens, this one is a bit less expensive, however when i try it its making a bit of noise and not really fast in focusing etc... (compared to the 55-250mm canon lens im currently using, the canon one is really good, in term of zoom in/out, forcusing without any noise...)

2nd: Canon 18-200mm IS lens, I prefer this one coz it has "Canon" brand also it doesnt make noise like the Tamron lens, however it couldnt zoom far comparing to the Tamron.... and if im not wrong, Canon doesnt have any 18-250mm lens....

Really appreciated if anyone can give me some idea on this... cause i need to buy one soon before my holiday...

Thanks in advance everyone
