我用梗450D，現在想買支天涯鏡，但睇咗好多網上用家意見，sigme同tamron到各有各好處(c記18-200mm還新未有資料 )，所以想問下，我用450d會同邊支鏡最夾。

1.Sigma 18-200mm F3.5-6.3 DC OS
2.Tamron AF18-270mm F/3.5-6.3 Di II VC LD Aspherical [IF] MACRO (B
3.Canon EF-S 18-200mm f/3.5-5.6 IS

新手一問，謝謝各位！

Any C Hing can recommend?

no. 2 range 大，又有 macro，首選。

Bought my sigma 18-200mm OS 2nd hand for almost 6mths. Had at least 7k shots out of it.

I use nikon D40 but I was told that the Canon one is just as good.

the range is very good already, although Tamron can proved better, without any stabliser I'm not sure if that extra 70mm will be any good. It's about physically getting closer to the subject than zooming in from way out anyway.

Marco has a production of 1:3.9 and with mine I can actually get it focus closer than what it said in the manual =p

I think this sigma gives you the best bang for what you have to pay. The only few things that the nikon one is better, f5.6@200mm, the VR is better than OS (3 stops compared to 2 stops)

As for canon, they havent make any bad lenses with IS on them, I should think that the 18-200mm IS would be better if the price is within your budget.

Tamron 18-270都有VC (Vibration Compensation)

but 18-200mm is a range that has lass distortion over the 18-200mm+ range though
