1. Tamron AF18-270mm F/3.5-6.3 Di II VC LD Aspherical [IF] MACRO (B
HKD 4170
2. Canon EF-S 18-200mm f/3.5-5.6 IS
HKD 4750
3. SIGMA 18-200mm F3.5-6.3 DC OS /HSM
HKD 3350

以上三支鏡都係我考慮的.當然錢銀有限,我心想選 SIGMA 但店萬X的人說 SIGMA 啲鏡有客反映 SIGMA 唔夠札實易壞.
Tamron 果支鏡有五年保養,但就對焦有點慢, 影像成像一般.
Canon 就當然貴啦 !!

以上三支鏡各位有冇用過比D意見呀!!

平野無好...
好野無平..
老生常談啦...
如自已不計較質素及2手價,
就無問題 o羅..
但如日後要升級換鏡就知道後悔 o羅..

sigma幾好，用得過。

同一環境下比較canon同sigma，肉睇好難睇倒有分別。

canon對焦快D，但sigma平好多。

Tamron AF18-270mm is good

所有天崖鏡成像都屬一般

只係200同270分別,天崖鏡多70差好遠

450D with Canon 18-200 F3.5-5.6 IS (my setup)
200.0mm (35mm equivalent: 323mm), f/5.6, 0.017 s (1/60), iso100


40D with Tamron 18-270 F3.5-6.3 VC (my friend's setup)
270.0mm (35mm equivalent: 437mm), f/6.3, 0.0040 s (1/250), iso400


Although not the same picture, but I would say both are equal, if not the sharpest.

But Canon at the far end at F5.6 should focus a bit faster. But Tamron at 200mm still has a max aperture of F5.6, it's only after that and up to 270mm that the max aperture is reduced to F6.3
